Customizing Grep

Here’s a script that I wrote to help me find things at work.

#!/bin/bash


if [ ! -n "$1" ]

then

  echo "Usage: `basename $0` pattern [optional args to grep]"

  echo "e.g. grepit findme -i"

  echo

  exit 1

fi

if [ ! -n "$2" ] then grep -r --exclude='*.log' "$1" * | grep -v '/.svn/' else grep -r "$2" --exclude='*.log' "$1" * | grep -v '/.svn/' fi

Basically I just got tired of always specifying the recursive option to grep and having to exclude svn and log files (because they were redundant or took too long to search). I also found that sometimes I wanted to add additional arguments (like -i for ignoring case or -n for line numbers). So now when I change a function in one file and want to find every place that function was used I simply do a

grepit function_name

P.S. Let me know if you know a good way to strip leading whitespace from the results.
