sankarramanv,
It seems for me that this task does not need both python AND shell. Only
python does it, as well as only shell.
Of course, there can be some restrictions let you use both. (the real world
is filled up with such troublesome matters !)
If you *really* need to use `lgrep`, try `-f` opt

I need to escape only the square brackets in above variable since its not
grepping without escaping the brackets.

You're putting this
Hi,
You don't need a regexp for this, the "replace" method on a string
will do what you want:
>>> s = 'this is a [string'
>>> print(s.replace('[', '\\['))
this is a \[string

Hi,
I have a requirement.
cmd="cat |grep -c 'if [ -t 1 ]; then mesg n 2>/dev/null; fi'"
I need to escape only the square brackets in above variable since its not
grepping without escaping the brackets.
Please help.
Thanks.

Hello,

Thank you Paul.
Since the only thing i'm doing is extracting this fields, and have no
plans to include other stuff, a regexp is fine. However i will take
into account 'pyparsing' when i need to do more complex parsing.
As you can see in the example i send, i was trying to get info from a
glade fi
Thank you, i have read this but somehow a missed it when the issue
arose.

As Peter Otten has already mentioned, this is the difference between the re

The thing is i should expected to have to put caret explicitly to tell
the regexp to match at the start of the line, something like:
r'^'
however python regexp is taking care of that for me. This is not a
desired behaviour for what i know about regexp, but maybe i'm missing
something.

Neat! I didn't realize that re.sub could take a function as an
argument. Thanks.

Hi Folks,
I'm trying to strip C/C++ style comments (/* ... */ or // ) from
source code using Python regexps.
If I don't have to worry about comments embedded in strings, it seems
pretty straightforward (this is what I'm using now):

In your case it may be simpler to just split the string into groups.

Thanks very much for that, I didn't even consider the option of it

On my machine the program finishes in 30 seconds. (it's a 1.5GHz machine)
If the 'parm' group is removed, or if the buffer is shortened, the time
is reduced considerably.
There are "pathological cases" for regular expressions which can take
quite a long time. In the case of your expression, it's

I have a string which I wish to match using RE, however when I run my
comparison (using the match method) on my machine it never returns,
using the CPU fully.
The code is (very simply):
--
import re
buffer = r"#1 1 550 111 SYNC_PEER RES
syncpeers=(id=54325432;add=10."
23 matches
