Reset Grep options GREP_OPTIONS shell variable


I was working through a grep tutorial and it had me do this:
export GREP_OPTIONS=’–color=auto’ GREP_COLOR=‘100;8’

How does one reset this change?


It appears that closing terminal and restarting it has reset itself. Would be nice to know how to revert the changes though…

Try unset command that unsets values and attributes of shell variables and functions:


For more info type:

help unset

or see my FAQ “How to undefine and unset a bash environment variable on Linux or Unix”.

Awesome! thinks for the info.
