Re^2: How to Remove Commas ?

ramlight,

Thanks for your post! I'm having the best success with your suggestion, some others caused perl to crash. :(

I pasted the snippet into my script ...

# while not eof
# =============
while ($line = <INPUT>) {

($date, $time, $ampm, $filesize, $filename) = split(" ", $line);

# remove commas from $filesize string
# ===================================
$filesize =~ s/,//;
[download]

and it successfully removed the first comma. (below)

Results from gnome-terminal:

The first comma was removed from each number. Now I'm off to perldoc.perl.org to see how I can remove the remaining commas.

Thanks ... Allen.

Have another read of the answer roboticus gave you, paying particular attention to the 'g' flag of the substitution. Cheers, JohnGG	[reply]

The first comma was removed from each number. The `s///` operator by default removes only the first match. So: `my $var = "foobarfoobaz"; $var =~ s/foo//; say $var; # says "barfoobaz"` [download] There are various flags you can include to alter its default behaviour though. One of the most useful is the "g" (global) flag... `my $var = "foobarfoobaz"; $var =~ s/foo//g; say $var; # says "barbaz"` [download] Note that the slashes may be replaced with other characters, so you could equally write: `my $var = "foobarfoobaz"; $var =~ s@foo@@g; say $var; # says "barbaz"` [download] Or even: `my $var = "foobarfoobaz"; $var =~ s{foo}{}g; say $var; # says "barbaz"` [download] ... which some people might find more readable. Though note that there are a handful of characters (hash, question mark and single quote spring to mind) that trigger special behaviours here (perlop has more details). `perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'`	[reply] [d/l] [select]
