Command to make a script running from every subdir

BudiKusasi · 07-10-2022, 09:51 PM

How is the find command (or else if better) to let us run a script from, i.e. relative to, every subdir under, and including, current working directory ?

illustratio e.g. script is

Code:

grep 'foo' *

Code:

find . -type d -exec sh -c 'cd {}; grep foo *' \;

Note that you have to execute a shell in order to expand the "*" in the target directories. Without that, the find command will just pass a literal "*" to the grep (or whatever) command, which will just complain that it can't find any file named "*".

I originally had a much more complex example using "-execdir", but found things were much simpler without it.

Not sure I follow but you can use -R option in grep to recurse subdirs

I believe grep was just an example, not the actual intended command.

Run the command 'recursively'.

Within the shell script filenames should be in quotes, and exit the cd status should matter.

Code:

find . -type d -exec sh -c 'cd "{}" && grep foo *' \

Code:

find . -type d -exec sh -c 'cd "{}" && pwd' \;

Portable (all find versions) is

Code:

find . -type d -exec sh -c 'cd "$0" && pwd' {} \;

or

Code:

find . -type d -exec sh -c 'cd "$1" && pwd' chdir.sh {} \;

Trying to modify this to be a coherent question:

How can the find command run a script against all of the found results?

All I have here is about the same with rknichols said in post #2, in fact that's my daily use of find.
As cited, you can run a script using the -exec argument.

Does that solve what you're trying to do? If not, maybe a more clear question?

Code:

grep -R foo

Your example should probably have used a different command.
