Search and Replace across multiple files

grep -lr -e '<oldword>' * | xargs sed -i 's/<oldword>/<newword>/g'
- grep for the word in a files, use recursion (to find files in sub directories), and list only file matches -| xargs passes the results from the grep command to sed -sed -i uses a regular expression (regex) to evaluate the change: s (search) / search word / target word / g (global replace)

What Others Think

If you are using grep's -r switch, thus running a recursive search, you can specify the present working directory name instead of the glob * in order to search for all files. That will also search for dot files and will be more efficient. i.e. grep -lr -e '<oldword>' . instead of grep -lr -e '<oldword>' *

Also I'd recommend -s -I grep options to skip read access errors and binary files
