Search and Replace across multiple files

- 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)

Alternatives

There are 3 alternatives - vote for the best!

Know a better way?

If you can do better, submit your command here.

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
