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

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.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
