Re^2: IO::Handles ... any good?

Quite a bit beyond me but... wow, I will use as a shell alias - thanks.
Here's my effort at decoding your line :

perl <br>
-i    #edit in place
.bak  #but make a new file
-p    # read every line from default arg
e     # excecute code from command line
'     #code for the default while loop
$_    # default variable, each line of file
.     # and
=     # equal to
"     #start printing this literally
\n    #new line
"     #finish literal printing
'     # end/start next loop

`perl -i # edit in place .bak # rename original file by appending .bak to filename; print to n +ew file with original name -p # use a while loop to read each file; print each line (is stored + in $_) which you have read (and modified) e # excecute code from command line ' # start of code to be executed (for the default while loop) $_ # default variable, each line of file .= # append the following to yourself ($_) and assign it to you "\n" # string to be appended ' # end of code` [download] `$_ .= "\n";` is the shorter form of `$_ = $_ . "\n";` Check perlrun and look for the explanation for option `-i`. They have some examples there. `-p` should be explained in more details, too.	[reply] [d/l] [select]

`-p` should be explained in more details, too. `-p` is nicely explained using Deparse. `>perl -MO=Deparse -pe"body()" LINE: while (defined($_ = <ARGV>)) { body(); } continue { die "-p destination: $!\n" unless print $_; } -e syntax OK` [download]	[reply] [d/l] [select]
