[SOLVED] How to use sed (or another Bash command) to replace a word or phrase with text logo and with strings?

Issue

I have a script that I want to use to replace a small text with a larger one

This is what I was testing:

I want to make the text:

exit 0

be replaced by this:

for dev in `ls /dev | egrep "^[sh]d[[:alpha:]][[:digit:]]+$"`; do umount "/dev/"$dev &>/dev/null ; gio mount -u /media/*/* ; gio mount -u /media/$USER/* ; done
exit 0

Solution

One potential solution using 'pipe' as a delimiter and escaping some special characters:

sed 's|exit 0|ls /dev \|egrep "^[sh]d[[:alpha:]][[:digit:]]+$"|'

# Example
echo "some text; exit 0; more text" | sed 's|exit 0|ls /dev \|egrep "^[sh]d[[:alpha:]][[:digit:]]+$"|'
some text; ls /dev |egrep "^[sh]d[[:alpha:]][[:digit:]]+$"; more text
