I know **/*.ext expands to all files in all subdirectories matching *.ext, but what is a similar expansion that includes all such files in the
**/*.ext
*.ext
$ find . -type f
That will list all of the files in the current directory. You can then do some other command on the output using -exec
$find . -type f -exec grep "foo" {} \;
That will grep each file from the find for the string "foo".
