Strawberry Perl regular expression, Windows 7 [duplicate]

Question

I'm trying to execute a simple search and replace at the command line.

I have a file called Test1.txt. The contents are "How are you doing today?"

At the command line, I have navigated to the folder in which the text file resides: C:\perl.

Here are the commands I've issued and the results/messages I'm getting:

perl -pi.bak -e 's/doing/feeling/g' Test1.txt

This creates the backup, but no observable change is made to Test1.txt even though it appears the file was modified as far as Windows explorer is concerned.

perl -pi.bak -e "BEGIN{@ARGV=<Test1.txt>} s/doing/feeling/g"

This makes the change and creates the backup, but I get the message:

-i used with no filenames on the command line, reading from STDIN

Is there a way to use -i with filenames on the command line? I found the BEGIN syntax elsewhere as the way to do it in Windows, but is there no other way to do it without getting this message?

Answer 1

I am not sure why, but using double quote instead of single makes it work.

perl -pi.bak -e "s/doing/feeling/g" Test1.txt
