Escaping shell characters

[George Moschovitis]

Hello everyone,

I have a small question:

I would like to use backtick (`) to execute a command line
program:

Is there a method in the standard ruby distribution that
allows me to escape a string for the command line shell?

for examle escape strings like this:

`my_programm --password=qw;2332;3`

should become

`my_programm --password=qw\;2332\;3`

Btw I need this method to be compatible with Windows too. I can
implement my own method of course, but I was wondering if there
is something available in ste standard libraries.

thanks in advance,
George.

If you don't need the output you could use system:

system "your_program", '--password=qw;2332;3'

You might as well use popen although that has some pecularities on Windows
systems.
