So I was lazy, like all good sysadmins…I wanted to put in an option to say “yes or no” in a bash script.
I started with a simple
if..then..elif..else statement, then I started googling around and found multiple ways to do it.
I ran the script a couple times, it worked like a charm, but without thinking about it I put
y instead of the suggested
yes and it
exit 1ed me. Do’h!
I continued googling around and then remembered the
I created this:
#!/bin/bash read -p "yes or no: " RESPONSE case "$RESPONSE" in yes|y|Yes|Y) echo "blah is yes" ;; no|n|No|N) echo "blah is no" ;; *) echo "You need to say yes or no, start over!" exit 1 ;; esac
Now you are probably wondering why I even bothered posting this. Honestly, I spent way too much time on this and I figured I’ll find myself looking for this again 6+ months down the line.
Hopefully this post will save you some time in the future.
