A simply retry tool in plain POSIX sh.
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 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
