Issue
Whenever I try to use RVM on Ubuntu or one of it's derivatives, I get the following error:
grep: invalid option -- 'p'
Usage: grep [OPTION]... PATTERN [FILE]...
Try 'grep --help' for more information.
I checked type grep, and got
grep is /bin/grep.
So grep is not aliased.
Is this a known bug in RVM? If not, what else could be causing this behavior?
EDIT: This occurs when I source ~/.bash_profile. I've gone and reproduced the behavior when I run just the RVM related part.
Solution
Remove the ps='ps ...' from your config, like .bashrc, or execute unalias ps and then run your RVM command.
