parsing command line args

[badarisj]

folks,

when i give a command-line of:
/tmp/test.pl -arg1 -arg2 -arg3 'value with spaces'
to unix-shell, my perl script has access to the command-line arguments
in the following neat array:

0 ARRAY(0x12b06c)
0 '-arg1'
1 '-arg2'
2 '-arg3'
3 'value with spaces'

now if i have a string for the command-line:

$cmd_str = "/tmp/test.pl -arg1 -arg2 -arg3 'value with spaces'" ;

any ideas on parsing the $cmd_str into a @ARGV array i have shown
above?

thanks,
-badari

I'm not quite sure what you intended to mean by this line: for a start,
@ARGV certainly doesn't have two 'element 0's.

0 '-arg1'
1 '-arg2'
2 '-arg3'
3 'value with spaces'

now if i have a string for the command-line:

$cmd_str = "/tmp/test.pl -arg1 -arg2 -arg3 'value with spaces'" ;

The Text:arseWords module will do this for you. I was fairly sure this
was in the FAQ, but a couple of reasonable searches didn't find it, so
I'm not terribly surprised you didn't either .

That's what caused me to not attempt an answer when I saw it.

perldoc -q split

How can I split a [character] delimited string except when inside [character]?

hi ben,

that was ouput from my perl debugger. sorry for confusing you.

perfect. just tested it and it works. The Text:arseWords module
has the routine 'shellwords' which mentions that it emulates
parsing of the command-line by many unix shells ( which is exactly
what i was looking for).

thanks,
