Question How to egrep multiple pattern
Hi everyone
i want to write a script to grep multiple pattern from all the file from a dir.

for example I want to get all the record number from XML file who's last name is asd, smith, dfrt,gokul,and sinha.
I tried

Code:
egrep('sinha'|'gokul'|'asd')

but it is not working

also i tried saving all the pattern to a file and then
Code:
grep-f pattern_file ads/dsds/dsds/dsd/actualfile

I might be doing something wrong but not able to figure it out.
Thanks
