Query regarding grep!!

[bhavya sg]

Hi,

I saw in PEP4 of python 2.5 that grep module has gone
obsolete in perl 2.5. But I am not able to find an
alternative for that.My doubt is "are the other forms
of grep like egrep and ggrep be used instead"?

cheers,
Spurthi

Of course you can always use grep as an external process (if the OS has
it). For example:

-------------------------------------------------------------------
In [1]: import subprocess

In [2]: out=subprocess.Popen( 'grep -i blah ./tmp/*',
stdout=subprocess.PIPE, shell=True ).communicate()[0]

In [3]: out
Out[3]: './tmp/ex.tex:Blah blah blah...\n'
