I have a variable, let's call it MYVAR and I want to cut the string "-bar"

I can match/preserve strings at the end of variables, but I don't remember
how to cut them when I don't know what the first part of the variable
might look like.
I don't want to resort to sed unless I have to, but I thought there was a
procmail way to do this.
You're probably vaguely picturing the method I use to split an email
address to address vs. domain portion - possible because the @ in the
middle is known to not be a valid character within either half.
From my published sandbox:
# get the From: address as an address component ONLY (no comments)
:0 h
CLEANFROM=|formail -IReply-To: -rtzxTo:
# username portion
:0
* CLEANFROM ?? ^\/[^(_at_)]+
{
FROM_USER=$MATCH
}
# domain portion
:0
* CLEANFROM ?? @\/.*
{
FROM_DOMAIN=$MATCH
}

Alternatley, you may be thinking of the recipe within listname_id.rc, which
strips "-owner" from a listname. From that rcfile:
# The second and third conditions were found in posts from Bart Schaefer
# dated 2002-07-18 - these optimize this fallback recipe so that it
# doesn't require the use of a shell, pipe, and sed to eliminate the -owner
# suffix.
#
# first, get the owner address (if the sender follows that syntax)
# Grab everything up through the last hyphen
# Grab everything except that last hyphen
# This is optimized to be one recipe, since MATCH will assume the set value
# after each condition line, and if the FIRST condition matches, the two that
# follow it definatley should.
:0E
* ^Sender:[ ]*\/[-A-Z0-9_+]+-owner
* MATCH ?? ^^\/.+-
* MATCH ?? ^^\/([^-]|-[^-])+
{
LISTNAME=$MATCH
}

I suspect that latter recipe there may prove more appropriate to what
you're attempting than the first.
