how to get the output of a grep command to a file inside a shell script
hi,

i wat to get the output of a grep command in a file. but when i am trying out the same grep command in the unix prompt its working fine.. i am getting the output properly.. but when i am writing the same command inside my shell script , its just creating a new output file with no contents inside.
