How can I embed that into an UNIX Korn shell script? Can't you `sprintf` to a variable, comma-munge it, and then print that? `$x = sprintf "%02d\/%02d\/%04d\ %02d\:%02d", $MM +1 , $DD , $YY + 1900 +, $hh, $mm; $x =~ s/(\d)(?=(\d{3})+(\D\|$))/$1\,/g; print $x;` [download] You could lose the interim variable on the way to print, but it's easier to follow as above. -QM -- Quantum Mechanics: The dreams stuff is made of	[reply] [d/l] [select]

Clarification, as I'm just starting with Perl, how do a write that perl syntax into a korn shell command line executable. By way of example, the ${NUM} value is passed in, and the "perl -e" and/or "perl -e and printf" syntax will print it with comma separators. NUM="1234567890" echo "${NUM} should print with comma separators" perl -e ????????????????	[reply]

I don't know what the ksh quoting differences might be, so assuming something rational... Use `@ARGV`. If you have quoting problems, use `qq//` and `q//` inside the one-liner, and single quotes around the one-liner: `> BLAH=$(perl -e 'for (@ARGV){s/(\d)(?=(\d{3})+(\D\|$))/$1\,/g;print qq +/$_\n/}' 12345678 876543210) 12,345,678 876,543,210 > echo $BLAH 12,345,678 876,543,210` [download] Note that this form will take multiple values, commafy them, and output them one per line. If you expect more than integers, see the other answers with decimals and other weirdness on how to change the regex. -QM -- Quantum Mechanics: The dreams stuff is made of	[reply] [d/l] [select]

I'm not a ksh user, but this script seems to work for me. === `cat ~/.local/bin/commafy #!/usr/bin/perl -nl $_ =~ s/(\d)(?=(\d{3})+(\D\|$))/$1\,/g; print;` [download] === My usage (to find out that a recent nix build used 18 GB of space): `$ find /nix/store -cmin -150 \| perl -nle '$sum+=-s "$_";END{print $sum +}' \| commafy 18,025,136,505` [download] 2018-12-16 Athanasius added code and paragraph tags	[reply] [d/l] [select]
