Help with regular expression
Hi All,

Need some help with a regular expression that I cant seem to work on. Say there is the following text -

Input
We all (need some) help some day (ps: when it rains) and I need to save some hay now.
During the rainy season (ps: when it might rain heavily) Seattle gets drenched but not (all of pacific) northwest.
one of the best things that could (ps: happen) with any one is winning a lottery(1 atlas)

Output
We all (need some) help some day and I need to save some hay now.
During the rainy season Seattle gets drenched but not (all of pacific) northwest.
one of the best things that could with any one is winning a lottery(1 atlas)



I only want to eliminate anything in parenthesis as long as it starts with ps:

here is what i did

Opera $cat text | sed 's/(ps:*.*)//g'

We all (need some) help some day and I need to save some hay now.
During the rainy season northwest.
one of the best things that could

...as you can see that is not working when there is any parenthesis after where it finds the ps:.

Please help.

Thanks
Manohar.
