Hi
I have a 350 MB file in unix and want to replace all the occurences of "+0100]" with "+0000]".
It could be easily achieved with a perl script, but unfortunately i don't know much of that.

i need some perl script which does that or anything else which serves the purpose.
something like

perl script.pl oldfilename.txt <oldstring> <newstring> > newfilename.txt

thanks
Khem

You can do that with this one-liner, just paste the line below into the command line, change file.txt to correct filename.
Original file will be renamed to e.g. file.txt.bak

perl -i.bak -pe 's/\+0100\]/+0000]/' file.txt
