how to run commandline perl on windows

[aodukoya]

Thanks that worked perfectly

Janitor note:- Original content follows:

I have a file sem.log on a Windows box and I have already installed perl, but when I try to run the following which is perfectly valid on Unix, on the window dos prompt I get an error...

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

I get the following error:

Can't find string terminator "'" anywhere before EOF at -e line 1.

Is there a valid way of running commandline perl on windows without having to create a file.

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.
