Hi,
The following will show the xyz variable inherited from the
environment. Is there a way only show variables (global, or both
global or local if in a function) defined in the current script?
Thanks.
$ cat main1.sh
#!/usr/bin/env bash
# vim: set noexpandtab tabstop=2:
compgen -v
$ xyz=abc ./main1.sh |tail -n 1
xyz

Regards,
Peng
