echo " -g string [REQUIRED] search string for grep"
echo " -f regex [REQUIRED] filemask for search "
echo " [-d directory] path to search [defaults to . ] "

echo "EXAMPLES: "
echo " fif -g \"hello\" -f \"(?i)^.*\.bas+$\" "
echo " searches all files maching the mask '*.bas' in the "
echo " current working directory for the string 'hello'. "
echo " "
echo " fif -g \"len\" -f \"(?i)^.*\.py+$\" -d /home/gmgauthier/Projects/code/python -v"
echo " searches all files maching the mask '*.py' in the "
echo " 'src/package' directory, for the string '.alen' "

echo "NOTES: "
echo " - something similar can be done with a single grep. "
echo " eg: 'grep -rnw ~/Projects/code/python/passwdtools -e '.*\.length.*'"
echo " However, the raw grep doesn't give you the "
echo " ability to choose which files to scan. "
echo ""
echo " - grep takes a simple search string "
echo " - the filemask can be either ERE or PCRE regex "
echo " - all searches are recursive "
