Default for the $COLUMNS

[bas081]

Some shells don't have the COLUMNS defined in certain cases.

This makes fold error: fold: invalid number of columns: ‘’

A sane default would be appreciated. Either really big or a standard width 80.

Simply changing $COLUMNS -> ${COLUMNS:-80} would be an improvement.

I have the same error when run 'chatgpt -p "Text"' or 'echo "Text" | chatgpt'.

I like the idea of this project but it does not cover my use-cases that well. I wrote something much simpler in bash that works for me. Maybe it helps this project or others: https://gist.github.com/bas080/2268473a12af12320d366b9dce7a0f6a

@BalurPoco Solved it by using at the start export COLUMNS=80
