search-replace.sh

This script takes an input file which is a list of text replacements and applies those replacements to all files in the current directory.

Usage: bash search-replace.sh renames.txt

where each line of renames.txt is of the form renames mysearchtext to myreplacetext.

Caution: if renames.txt is in the current directory then this script will act on that file and make it useless for future invocations.
