perl special character

OFC_EDM — Tue, 15 Apr 2008 10:19:38 GMT

I'm trying to find the line
#DISABLETIME=48 (or any 2 digit value)

and replace with

DISABLETIME=60 (note: now uncommented)

My command is
perl -pi.old -e 's/\b\\#DISABLETIME=\d\d\b/DISABLETIME=60/' filename

Where I've tried escaping the # character. Also tried various forms of quoting etc. but without success.

What's wrong with my command?

Cheers

Hi:

Make the boundry (\b) and optional match:

# perl -pi.old -e 's/\b?\#DISABLETIME=\d\d\b/DISABLETIME=60/' filename

Regards!

Not sure I understand why that works...but it does.

Thanks James

(who also provided the original code as a solution for me in a different thread!! :)
