set -u captures error/warning

[ORESoftware]

I have a bash script that calls set -u

I got this error in my terminal

bash: rvm_bash_nounset: unbound variable

not sure if this is expected or not, but if not, maybe look up set -u, I just started playing with it so, just experimenting here. my script had nothing to do with RVM.

The error happened when RVM was sourced by the shell, so common path methinks...

set -u
This option causes the bash shell to treat unset variables as an error and exit immediately. This brings us much closer to the behavior of higher-level languages.

@ORESoftware, something in your script ended up calling rvm_bash_nounset. Try adding set -x to your script to print out line by line script execution. This may help pinpoint your issue.
