Command-interpreters on non-Unix systems have rather different ideas on quoting than Unix shells. You'll need to learn the special characters in your command-interpreter ("*", "\" and """ are common) and how to protect whitespace and these characters to run one-liners (see -e below).

On some systems, you may have to change single-quotes to double ones, which you must *not* do on Unix or Plan 9 systems. You might also have to change a single % to a %%.

For example:

        # Unix
        perl -e 'print "Hello world\n"'

        # MS-DOS, etc.
        perl -e "print \"Hello world\n\""

        # Macintosh
        print "Hello world\n"
         (then Run "Myscript" or Shift-Command-R)

        # VMS
        perl -e "print ""Hello world\n"""

The problem is that none of this is reliable...

perl -ane " $total += $F[9]; END {print $total} " sem.log
