Thanks for all your answers!
I settled for the simplest of them all, by single quoting the shell
variables:
> perl -wne 'if (/'$FILENAME'/) { s/\d{4}-\d{2}-\d{2}/'$UPDATED'/;print;

The reason I use bash here and not only good old perl is that the bash
script is much bigger
Hi!
I have a problem with variables when using command-line perl in a bash
script. The script should update a date (in 2003-10-10 form) if the

Hi People,
I have a silly little list-parsing problem that I can't get my head
