A simply retry tool in plain POSIX sh.
## How to use
Simply call
```
retry $cmd
```
to execute `$cmd` and on failure retry multiple times with some waiting time
between calls. Multiple command line parameters exist to tweak execution.
It is possible to specify no waiting time if desired:
```
retry -s 0 $cmd
```
If it is necessary to specify command line parameters to `$cmd` separate the
arguments with `--` like this:
```
retry -- $cmd --my-argument -X 3
```
Often it is desired to command the execution with a timeout. This can be done
with the `timeout` command from [GNU
coreutils](https://www.gnu.org/software/coreutils/) already present on many
systems. Either use with a global timeout:
```
timeout 10 retry $cmd
```
to execute `$cmd` with retrying but only wait up to 10s in total. Or with a
timeout per execution:
```
retry -- timeout 10 $cmd
```
