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...
So you'd have to try something like
perl -ane " $total += $F[9]; END {print $total} " sem.log

Hi,
Use " (double quotes) instead of single quotes.
perl -ane "$total += $F9; END {print $total}" sem.log
Update: Ah, PodMaster has already posted the answer.
