I have a string test.cgi@action=<action-name>
<action-name> can be any string
I would like to replace the above string with <action-name>.html
Can any one please let me know how I can proceed with this using a Perl script?

can you clarify what you would like to replace with .html ? the entire string or just .cgi ?manku– manku2011-07-01 10:04:41 +00:00Commented Jul 1, 2011 at 10:04

Given the data you've shown us, it's hard to see why: $string .= '.html'; isn't the answer :-)Dave Cross– Dave Cross2011-07-01 12:28:45 +00:00Commented Jul 1, 2011 at 12:28

Thanks for your suggestion. I will try this out...if I extend this to all the files within a directory...how ca I implement this?...i.e replace all the files with names test.cgi@action=<action-name> as <action-name>.html??

So you're trying to rename a bunch of files? That's really not related to the question you asked originally, but you can do that with the
rename command. For example: rename 's/^test\.cgi\@action=(.*)$/$1.html/' test.cgi*progster
Yes, I'm looking for both issues. Btw, rename command seems not to work. I have a file test.cgi@action=manager and i'm expecting to get renamed to manager.html, but it doesn't work. Can you please let me know how to resolve this?. or how i can debug this.

I tried with following code, but this doesn't replace the string : my $string = 'test.cgi@action=xxxxxxxxxxxxxxxx test.cgi@action=aaaaaayyyyyyyyyyytest.cgi@action='; $string =~ s/test\.cgi@action=(.*)/$1.html/; print $string;

What result are you expecting when your string contians multiples of these address-like substrings?
