+.Sh NAME
+.Nm kill
+.Nd terminate or signal a process
+.Sh SYNOPSIS
+.Nm
+.Op Fl s Ar signal_name
+.Ar pid
+\&...
+.Nm
+.Fl l
+.Op Ar signal_number
+.Nm
+.Fl signal_name
+.Ar pid
+\&...
+.Nm
+.Fl signal_number
+.Ar pid
+\&...
+.Sh DESCRIPTION
+The
+.Nm
+utility sends a signal to the process(es) specified
+by the pid operand(s).
+.Pp
+Only the super-user may send signals to other users' processes.
+.Pp
+The options are as follows:
+.Pp
+.Bl -tag -width Ds
+.It Fl s Ar signal_name
+A symbolic signal name specifying the signal to be sent instead of the
+default
+.Dv TERM .
+.It Fl l Op Ar signal_number
+If no operand is given, list the signal names; otherwise, write
+the signal name corresponding to
+.Ar signal_number
+provided.
+.It Fl signal_name
+A symbolic signal name specifying the signal to be sent instead of the
+default
+.Dv TERM .
+.It Fl signal_number
+A non-negative decimal integer, specifying the signal to be sent instead
+of the default
+.Dv TERM .
+.El
+.Pp
+The following pids have special meanings:
+.Bl -tag -width Ds -compact
+.It -1
+If superuser, broadcast the signal to all processes; otherwise broadcast
+to all processes belonging to the user.
+.It 0
+Broadcast the signal to all processes in the current process group
+belonging to the user.
+.El
+.Pp
+Some of the more commonly used signals:
+.Bl -tag -width Ds -compact
+.It 1
+HUP (hang up)
+.It 2
+INT (interrupt)
+.It 3
+QUIT (quit)
+.It 6
+ABRT (abort)
+.It 9
+KILL (non-catchable, non-ignorable kill)
+.It 14
+ALRM (alarm clock)
+.It 15
+TERM (software termination signal)
+.El
+.Pp
+.Nm
+is a built-in to
+.Xr csh  1  ;
+it allows job specifiers of the form ``%...'' as arguments
+so process id's are not as often used as
+.Nm
+arguments.
+See
+.Xr csh  1
+for details.
+.Sh SEE ALSO
+.Xr csh 1 ,
+.Xr pgrep 1 ,
+.Xr pkill 1 ,
+.Xr ps 1 ,
+.Xr kill 2 ,
+.Xr sigaction 2 ,
+.Xr signal 7
+.Sh STANDARDS
+The
+.Nm
+function is expected to be
+.St -p1003.2
+compatible.
+.Sh HISTORY
+A
+.Nm
+command appeared in
+.At v6 .

+.Sh NAME
+.Nm printf
+.Nd formatted output
+.Sh SYNOPSIS
+.Nm
+.Ar format
+.Op Ar arguments  ...
+.Sh DESCRIPTION
+.Nm
+formats and prints its arguments, after the first, under control
+of the
+.Ar format  .
+The
+.Ar format
+is a character string which contains three types of objects: plain characters,
+which are simply copied to standard output, character escape sequences which
+are converted and copied to the standard output, and format specifications,
+each of which causes printing of the next successive
+.Ar argument  .
+.Pp
+The
+.Ar arguments
+after the first are treated as strings if the corresponding format is
+either
+.Cm b ,
+.Cm B ,
+.Cm c ,
+or
+.Cm s ;
+otherwise it is evaluated as a C constant, with the following extensions:
+.Pp
+.Bl -bullet -offset indent -compact
+.It
+A leading plus or minus sign is allowed.
+.It
+If the leading character is a single or double quote, the value is the
+.Tn ASCII
+code of the next character.
+.El
+.Pp
+The format string is reused as often as necessary to satisfy the
+.Ar arguments  .
+Any extra format specifications are evaluated with zero or the null
+string.
+.Pp
+Character escape sequences are in backslash notation as defined in
+.St -ansiC .
+The characters and their meanings are as follows:
+.Bl -tag -width Ds -offset indent
+.It Cm \ee
+Write an
+.Aq escape
+character.
+.It Cm \ea
+Write a
+.Aq bell
+character.
+.It Cm \eb
+Write a
+.Aq backspace
+character.
+.It Cm \ef
+Write a
+.Aq form-feed
+character.
+.It Cm \en
+Write a
+.Aq new-line
+character.
+.It Cm \er
+Write a
+.Aq carriage return
+character.
+.It Cm \et
+Write a
+.Aq tab
+character.
+.It Cm \ev
+Write a
+.Aq vertical tab
+character.
+.It Cm \e\'
+Write a
+.Aq single quote
+character.
+.It Cm \e"
+Write a
+.Aq double quote
+character.
+.It Cm \e\e
+Write a backslash character.
+.It Cm \e Ns Ar num
+Write an 8\-bit character whose
+.Tn ASCII
+value is the 1\-, 2\-, or 3\-digit octal number
+.Ar num .
+.It Cm \ex Ns Ar xx
+Write an 8\-bit character whose
+.Tn ASCII
+value is the 1\- or 2\-digit hexadecimal number
+.Ar xx .
+.El
+.Pp
+Each format specification is introduced by the percent character
+.Pq Dq \&% .
+The remainder of the format specification includes,
+in the following order:
+.Bl -tag -width Ds
+.It Zero or more of the following flags :
+.Bl -tag -width Ds
+.It Cm #
+A
+.Sq #
+character specifying that the value should be printed in an
+.Dq alternative form .
+For
+.Cm b ,
+.Cm c ,
+.Cm d ,
+and
+.Cm s
+formats, this option has no effect.
+For the
+.Cm o
+format the precision of the number is increased to force the first
+character of the output string to a zero.
+For the
+.Cm x
+.Pq Cm X
+format, a non-zero result has the string
+.Li 0x
+.Pq Li 0X
+prepended to it.
+For
+.Cm e ,
+.Cm E ,
+.Cm f ,
+.Cm g ,
+and
+.Cm G
+formats, the result will always contain a decimal point, even if no
+digits follow the point (normally, a decimal point only appears in the
+results of those formats if a digit follows the decimal point).
+For
+.Cm g

+.Pp
+A field width or precision may be
+.Sq Cm \&*
+instead of a digit string.
+In this case an
+.Ar argument
+supplies the field width or precision.
+.Pp
+The format characters and their meanings are:
+.Bl -tag -width Fl
+.It Cm diouXx
+The
+.Ar argument
+is printed as a signed decimal (d or i), unsigned octal, unsigned decimal,
+or unsigned hexadecimal (X or x), respectively.
+.It Cm f
+The
+.Ar argument
+is printed in the style
+.Sm off
+.Pf [\-]ddd Cm \&. No ddd
+.Sm on
+where the number of d's
+after the decimal point is equal to the precision specification for

+If the precision is missing, 6 digits are given; if the precision
+is explicitly 0, no digits and no decimal point are printed.
+.It Cm eE
+The
+.Ar argument
+is printed in the style
+.Sm off
+.Pf [\-]d Cm \&. No ddd Cm e No \\*(Pmdd
+.Sm on
+where there
+is one digit before the decimal point and the number after is equal to
+the precision specification for the argument; when the precision is
+missing, 6 digits are produced.
+An upper-case E is used for an
+.Sq E
+format.
+.It Cm gG
+The
+.Ar argument
+is printed in style
+.Cm f
+or in style
+.Cm e
+.Pq Cm E
+whichever gives full precision in minimum space.
+.It Cm b
+Characters from the string
+.Ar argument
+are printed with backslash-escape sequences expanded.
+.br
+The following additional backslash-escape sequences are supported:
+.Bl -tag -width Ds
+.It Cm \ec
+Causes
+.Nm
+to ignore any remaining characters in the string operand containing it,
+any remaining string operands, and any additional characters in
+the format operand.
+.It Cm \e0 Ns Ar num
+Write an 8\-bit character whose
+.Tn ASCII
+value is the 1\-, 2\-, or 3\-digit
+octal number
+.Ar num .
+.It Cm \e^ Ns Ar c
+Write the control character
+.Ar c .
+Generates characters `\e000' through `\e037`, and `\e177' (from `\e^?').
+.It Cm \eM\- Ns Ar c
+Write the character
+.Ar c
+with the 8th bit set.
+Generates characters `\e241' through `\e376`.
+.It Cm \eM^ Ns Ar c
+Write the control character
+.Ar c
+with the 8th bit set.
+Generates characters `\e000' through `\e037`, and `\e177' (from `\eM^?').
+.El
+.It Cm B
+Characters from the string
+.Ar argument
+are printed with unprintable characters backslash-escaped using the
+.Sm off
+.Pf ` Cm \e Ar c No ',
+.Pf ` Cm \e^ Ar c No ',
+.Pf ` Cm \eM\- Ar c No '
+or
+.Pf ` Cm \eM^ Ar c No ',
+.Sm on
+formats described above.
+.It Cm c
+The first character of
+.Ar argument
+is printed.
+.It Cm s
+Characters from the string
+.Ar argument
+are printed until the end is reached or until the number of characters
+indicated by the precision specification is reached; if the
+precision is omitted, all characters in the string are printed.
+.It Cm \&%
+Print a `%'; no argument is used.
+.El
+.Pp
+In no case does a non-existent or small field width cause truncation of
+a field; padding takes place only if the specified field width exceeds
+the actual width.
+.Sh EXIT STATUS
+.Nm
+exits 0 on success, 1 on failure.
+.Sh SEE ALSO
+.Xr echo 1 ,
+.Xr printf 3 ,
+.Xr vis 3 ,
+.Xr printf 9
+.Sh STANDARDS
+The
+.Nm
+utility conforms to
+.St -p1003.1-2001 .
+.Pp
+Support for the floating point formats and `*' as a field width and precision
+are optional in POSIX.
+.Pp
+The behaviour of the %B format and the \e', \e", \exxx, \ee and
+\e[M][\-|^]c escape sequences are undefined in POSIX.
+.Sh BUGS
+Since the floating point numbers are translated from
+.Tn ASCII
+to floating-point and
+then back again, floating-point precision may be lost.
+.Pp
+Hexadecimal character constants are restricted to, and should be specified
+as, two character constants.
+This is contrary to the ISO C standard but
+does guarantee detection of the end of the constant.

+.Sh NAME
+.Nm test ,
+.Nm \&[
+.Nd condition evaluation utility
+.Sh SYNOPSIS
+.Nm test
+.Ar expression
+.Nm \&[
+.Ar expression Cm ]
+.Sh DESCRIPTION
+The
+.Nm test
+utility evaluates the expression and, if it evaluates
+to true, returns a zero (true) exit status; otherwise
+it returns 1 (false).
+If there is no expression, test also
+returns 1 (false).
+.Pp
+All operators and flags are separate arguments to the
+.Nm test
+utility.
+.Pp
+The following primaries are used to construct expression:
+.Bl -tag -width Ar
+.It Fl b Ar file
+True if
+.Ar file
+exists and is a block special
+file.
+.It Fl c Ar file
+True if
+.Ar file
+exists and is a character
+special file.
+.It Fl d Ar file
+True if
+.Ar file
+exists and is a directory.
+.It Fl e Ar file
+True if
+.Ar file
+exists (regardless of type).
+.It Fl f Ar file
+True if
+.Ar file
+exists and is a regular file.
+.It Fl g Ar file
+True if
+.Ar file
+exists and its set group ID flag
+is set.
+.It Fl h Ar file
+True if
+.Ar file
+exists and is a symbolic link.
+.It Fl k Ar file
+True if
+.Ar file
+exists and its sticky bit is set.
+.It Fl n Ar string
+True if the length of
+.Ar string
+is nonzero.
+.It Fl p Ar file
+True if
+.Ar file
+is a named pipe
+.Po Tn FIFO Pc .
+.It Fl r Ar file
+True if
+.Ar file
+exists and is readable.
+.It Fl s Ar file
+True if
+.Ar file
+exists and has a size greater
+than zero.
+.It Fl t Ar file_descriptor
+True if the file whose file descriptor number
+is
+.Ar file_descriptor
+is open and is associated with a terminal.
+.It Fl u Ar file
+True if
+.Ar file
+exists and its set user ID flag
+is set.
+.It Fl w Ar file
+True if
+.Ar file
+exists and is writable.
+True
+indicates only that the write flag is on.
+The file is not writable on a read-only file
+system even if this test indicates true.
+.It Fl x Ar file
+True if
+.Ar file
+exists and is executable.
+True
+indicates only that the execute flag is on.
+If
+.Ar file
+is a directory, true indicates that
+.Ar file
+can be searched.
+.It Fl z Ar string
+True if the length of
+.Ar string
+is zero.
+.It Fl L Ar file
+True if
+.Ar file
+exists and is a symbolic link.
+This operator is retained for compatibility with previous versions of
+this program.
+Do not rely on its existence; use
+.Fl h
+instead.
+.It Fl O Ar file
+True if
+.Ar file
+exists and its owner matches the effective user id of this process.
+.It Fl G Ar file
+True if
+.Ar file
+exists and its group matches the effective group id of this process.
+.It Fl S Ar file
+True if
+.Ar file
+exists and is a socket.
+.It Ar file1 Fl nt Ar file2
+True if
+.Ar file1
+exists and is newer than
+.Ar file2 .
+.It Ar file1 Fl ot Ar file2
+True if
+.Ar file1
+exists and is older than
+.Ar file2 .
+.It Ar file1 Fl ef Ar file2
+True if
+.Ar file1
+and
+.Ar file2
+exist and refer to the same file.
+.It Ar string
+True if
+.Ar string
+is not the null
+string.
+.It Ar \&s\&1 Cm \&= Ar \&s\&2
+True if the strings
+.Ar \&s\&1
+and
+.Ar \&s\&2
+are identical.
+.It Ar \&s\&1 Cm \&!= Ar \&s\&2
+True if the strings
+.Ar \&s\&1
+and
+.Ar \&s\&2
+are not identical.
+.It Ar \&s\&1 Cm \&\*[Lt] Ar \&s\&2
+True if string
+.Ar \&s\&1
+comes before
+.Ar \&s\&2
+based on the ASCII value of their characters.
+.It Ar \&s\&1 Cm \&\*[Gt] Ar \&s\&2
+True if string
+.Ar \&s\&1
+comes after
+.Ar \&s\&2
+based on the ASCII value of their characters.
+.It Ar \&n\&1 Fl \&eq Ar \&n\&2
+True if the integers
+.Ar \&n\&1
+and
+.Ar \&n\&2
+are algebraically
+equal.
+.It Ar \&n\&1 Fl \&ne Ar \&n\&2
+True if the integers
+.Ar \&n\&1
+and
+.Ar \&n\&2
+are not
+algebraically equal.
+.It Ar \&n\&1 Fl \&gt Ar \&n\&2
+True if the integer
+.Ar \&n\&1
+is algebraically
+greater than the integer
+.Ar \&n\&2 .
+.It Ar \&n\&1 Fl \&ge Ar \&n\&2
+True if the integer
+.Ar \&n\&1
+is algebraically
+greater than or equal to the integer
+.Ar \&n\&2 .
+.It Ar \&n\&1 Fl \&lt Ar \&n\&2
+True if the integer
+.Ar \&n\&1
+is algebraically less
+than the integer
+.Ar \&n\&2 .
+.It Ar \&n\&1 Fl \&le Ar \&n\&2
+True if the integer
+.Ar \&n\&1
+is algebraically less
+than or equal to the integer
+.Ar \&n\&2 .
+.El
+.Pp
+These primaries can be combined with the following operators:
+.Bl -tag -width Ar
+.It Cm \&! Ar expression
+True if
+.Ar expression
+is false.
+.It Ar expression1 Fl a Ar expression2
+True if both
+.Ar expression1
+and
+.Ar expression2
+are true.
+.It Ar expression1 Fl o Ar expression2
+True if either
+.Ar expression1
+or
+.Ar expression2
+are true.
+.It Cm \&( Ns Ar expression Ns Cm \&)
+True if expression is true.
+.El
+.Pp
+The
+.Fl a
+operator has higher precedence than the
+.Fl o
+operator.
+.Sh GRAMMAR AMBIGUITY
+The
+.Nm test
+grammar is inherently ambiguous.
+In order to assure a degree of consistency, the cases described in
+.St -p1003.2
+section 4.62.4,
+are evaluated consistently according to the rules specified in the
+standards document.
+All other cases are subject to the ambiguity in the command semantics.
+.Sh EXIT STATUS
+The
+.Nm test
+utility exits with one of the following values:
+.Bl -tag -width Ds
+.It 0
+expression evaluated to true.
+.It 1
+expression evaluated to false or expression was
+missing.
+.It \*[Gt]1
+An error occurred.
+.El
+.Sh STANDARDS
+The
+.Nm test
+utility implements a superset of the
+.St -p1003.2
+specification.
