Subject: System calls with ` in parameters

Hi All,

I am trying to add functionality to an interesting script.  The part
that is tripping me up is that I have to make a system call to echo, and
feed several parameters.  One of the parameters occasionally includes
the ` character.

Because of this, the syntax of:

`echo "#{someVar}" | ./some-script.py > "#{outputFile}"`

is breaking when #{someVar} contains the tick `.  This causes the
command to fail because it executes up to the tick ` in someVar and not
to the end as intended.

I have also tried using the system() command as follows:

system("echo \"#{someVar}\" | ./some-script.py > \"#{outputFile}\"")

But this fails when there is a tick ` in #{someVar} as well.

Any help would be appreciated.

Thanks,
Gerad
