To see what Perl uses,

$ perl -le'use Config; print $Config{sh}' /bin/sh

But note that on many systems, /bin/sh is bash.

$ /bin/sh -c 'echo $SHELL' /bin/bash

If you want to use an alternate shell,

sub backticks_mysh { open(my $pipe, '-|', '/bin/mysh', '-c', $_[0]) or return; local $/ = wantarray ? $/ : undef; <$pipe> }

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 How to display code and escape characters are good places to start.
