Recursive Sed Against Files that Match a Directory Pattern

Is there an easy way to use

which contained the following text:


I could run the following:

sed -i -e 's/foo/bar/g' somedir/example.txt

Resulting in the text of the file being:


Is there a way to specify a directory pattern like:


Which would recursively update any
file under the

If you have bash version 4, run

shopt -s globstar
sed -i -e 's/foo/bar/g' somedir/**/example.txt

If you have an earlier version bash or just a POSIX shell, then run:

find somedir -type f -name 'example.txt' -exec sed -i -e 's/foo/bar/g' {} +

For OSX:

find somedir -type f -name 'example.txt' -exec sed -i '' -e 's/foo/bar/g' {} +


From man bash (version 4+):

If set, the pattern ** used in a pathname expansion context will match all files and zero or more directories and subdirectories. If the pattern is followed by a /, only directories and subdirectories match.
