Finding

$ grep -rnw 'directory' -e "pattern"

-r is recursive, -n is line number and -w stands match the whole word. Along with these, --exclude or --include parameter could be used for efficient searching. Something like below:

$ grep --include={*.c,*.h} -rnw 'directory' -e "pattern"

This will only search through the files which have .c or .h extensions. Similarly a sample use of --exclude:

$ grep --exclude=*.o -rnw 'directory' -e "pattern"

Above will exclude searching all the files ending with .o extension.

Some options

• i stands for upper/lower case (optional in your case)
• ...
