Re: Best way to write in Perl

hello fellow monk,

yes there is a facility in perl to modify a file (i.e. to do inline replacement)

 perl -pi -e 's/MONK/SAINT/ig' abc.txt

The above file will replace all the instances of MONK to SAINT in the file abc.txt

hope it helps,

Blessings,
a perl Monk

I think you forgot to create a backup of the file. I tried: `perl -pi -e 's/MONK/SAINT/ig abc.txt` [download] and get: `Can't do inplace edit without backup.` [download] If you change that to: `perl -pib -e 's/MONK/SAINT/ig' abc.txt` [download] Then it works ;) Smoothie, smoothie, hundre prosent naturlig!

Actually, just specifying -i will work on most platforms. Cf perldiag : `Can’t do inplace edit without backup (F) You’re on a system such as MS-DOS that gets confused if + you try reading from a deleted (but still opened) file. You have t +o say "-i.bak", or some such.` [download]	[reply] [d/l]
