Subject: How to compare for control codes in a string
X-Mailer: MH-E 8.6+git; GNU Mailutils 3.16; Emacs 29.1
--------
I want to see if the 1st character in a string is a formfeed and then remove it.
I use the following script to check it
if [[ $line[1] == '\f' ]] # Check if the 1st character is a formfeed
then tmpline=${line[@]:1} # strip the ^f off
fi
but it's not working. How should it be checked?
Thank you.
