Perl: replace character in file


Hello,

I've read all the topics on this problem, the solution works, but not for my specific problem.

I want to replace a dot by a comma in a .txt file

This should be possible by doing this on the command line:

/usr/bin/perl -p -i.bak -e "s/./,/g" *.txt

This returns the *.txt file full with comma's (and a .bak backup file), it replaced every character with a comma.

If I do this:

/usr/bin/perl -p -i.bak -e "s/i/,/g" *.txt

then it works fine and it replaces every 'i' with a comma.

So it seems it does work with every character, except dots


It might be a noobisch question, but can somebody help me to fix this?

But do you understand? The '.' means match any character, so if you want to match the literal '.', you have to escape it with a \.

Yes, I understand now, figured that . means every character. Didn't know about the '\' escape
