Implementing dry-run in bash scripts
- by Andrei Serdeliuc
How would one implement a dry-run option in a bash script?
I can think of either wrapping every single command in an if and echoing out the command instead of running it if the script is running with dry-run.
Another way would be to define a function and then passing each command call through that function.
Something like:
function _run () {
if [[ "$DRY_RUN" ]]; then
echo $@
else
$@
fi
}
`_run mv /tmp/file /tmp/file2`
`DRY_RUN=true _run mv /tmp/file /tmp/file2`
Is this just wrong and there is a much better way of doing it?
