Loop through directory and run a command

Question

I want to run the following command

./mc cp --recursive local//first/second remote//first/second

I want to loop through local//first and find all directories and run ./mc cp for each directories

How can I do this?

It's not important , I just want to run a command in a loop can you help me to iterate over directory and run the command multiple time? — A.A

Why don't you just do a cp --recursive //first remote//first? The whole point of recursive is that it goes recursively through all intries below the starting directory. No need ot write a loop then. — user1934428

You can use find tool to do such thing

find . -type d -exec echo {} \;

your command would something be like

find . -type d -exec ./mc cp --recursive "local/{}" "remote/{}" \;

If local//first only contains directories, this should work for you:

./mc cp -r local//first/* remote//first

For a general case you can also use find to list all directories:

find local//first -type d

Then do whatever with this list using -exec or pipe it into xargs:

find local//first -type d -path "local//first/*" -prune -exec ./mc cp --recursive {} remote//first \;

Read more in documentation (find, xargs).
