grep problem

Hi

I would like to know wheather there is anyway to pass a variable to grep argument like this

grep "$myvar" $myfile

i would put this in a function and then call this function by setting different values to myvar and myfile.

is this possible at all.

regards
Hrishy

Yeah, give it a shot, let us know if you have any problems with it! I'm pretty sure what you're describing will work - I have written similar scripts in the past.

you could try it. but from what i recall. by default grep will take 2 arguemnts. and if the argument is part of the metacharter set it ie your "$" will make the next charters a variable.

First: try without any quotes. if that does not work try w/ single quotes around each variable.

also makesure you echo your variable befor the grep statement (just for testing) to make sure you are passing information to the variable.
