Yes but having a problem on how to use sys.argv to check every argument against a set of options. I'm just starting playing in python as I would need to use arithmetic computations which are messy to do using csh.

The arguments passed will be something like this:

Code:
python myscript.py -FDRW1=file1 -FDRW2=file2- 		@page { size: 8.5in 11in; margin: 0.79in } 		P { margin-bottom: 0.08in } 	-->

I get each arguments e.g. -FDRW1=file1 and seperate the two things on either side of '='.

Have got something like this coded in a csh script. Need to do something similar.

Code:
  set narg = $#argv
  while ($iarg < $narg)

    MATH iarg = $iarg + 1
    set arg = $argv[$iarg]
    set opt = ` echo $arg | awk 'BEGIN { FS="=" } { print $1 }' `
    set par = ` echo $arg | awk 'BEGIN { FS="=" } { print $2 }' `

# Change options to upper case.
# Use tr "[A-Z]" "[a-z]" to change from upper to lower case)
    set opt = ` echo $opt | tr "[a-z]" "[A-Z]" `
    echo "opt = $opt"

    switch ($opt)
    case "-FDRW1":
        set Afdrw1 = $par
        set fdrw1 = `echo $Afdrw1 | awk 'BEGIN {FS=".log"} {print $1}'`
        set nxz = `echo $fdrw1 | awk 'BEGIN{FS="-"} {print $NF}'`
        set optfdrw1 = 1
        set optfdrw = 1
        breaksw
    case "-FDRW2":
        set Afdrw2 = $par
        set fdrw2 = `echo $Afdrw2 | awk 'BEGIN {FS=".log"} {print $1}'`
        set optfdrw2 = 1
        set optfdrw = 1
        breaksw
   default:
      set Aerr = $arg
      set ierr = 1
      breaksw
    endsw

  end   # while

idle

IDLE(1) 						      General Commands Manual							   IDLE(1)

NAME

       IDLE - An Integrated DeveLopment Environment for Python

SYNTAX

       idle [ -dins ] [ -t title ] [ file ...]

       idle [ -dins ] [ -t title ] ( -c cmd | -r file ) [ arg ...]

       idle [ -dins ] [ -t title ] - [ arg ...]

DESCRIPTION

       This  manual page documents briefly the idle command.  This manual page was written for Debian because the original program does not have a
       manual page.  For more information, refer to IDLE's help menu.

       IDLE is an Integrated DeveLopment Environment for Python. IDLE is based on Tkinter, Python's bindings to the Tk widget  set.  Features  are
       100%  pure  Python, multi-windows with multiple undo and Python colorizing, a Python shell window subclass, a debugger. IDLE is cross-plat-
       form, i.e. it works on all platforms where Tk is installed.

OPTIONS

       -h     Print this help message and exit.

       -n     Run IDLE without a subprocess (see Help/IDLE Help for details).

       The following options will override the IDLE 'settings' configuration:

       -e     Open an edit window.

       -i     Open a shell window.

       The following options imply -i and will open a shell:

       -c cmd Run the command in a shell, or

       -r file
	      Run script from file.

       -d     Enable the debugger.

       -s     Run $IDLESTARTUP or $PYTHONSTARTUP before anything else.

       -t title
	      Set title of shell window.

       A default edit window will be bypassed when -c, -r, or - are used.

       [arg]* and [file]* are passed to the command (-c) or script (-r) in sys.argv[1:].

EXAMPLES

       idle   Open an edit window or shell depending on IDLE's configuration.

       idle foo.py foobar.py
	      Edit the files, also open a shell if configured to start with shell.

       idle -est "Baz" foo.py
	      Run $IDLESTARTUP or $PYTHONSTARTUP, edit foo.py, and open a shell window with the title "Baz".

       idle -c "import sys; print sys.argv" "foo"
	      Open a shell window and run the command, passing "-c" in sys.argv[0] and "foo" in sys.argv[1].

       idle -d -s -r foo.py "Hello World"
	      Open a shell window, run a startup script, enable the debugger, and run foo.py, passing "foo.py" in sys.argv[0] and "Hello World" in
	      sys.argv[1].

       echo "import sys; print sys.argv" | idle - "foobar"
	      Open a shell window, run the script piped in, passing '' in sys.argv[0] and "foobar" in sys.argv[1].
