Do something in all first level subdirectories linux command shell

That doesn't get all subdirectories. I assume you mean for the '*' to be replaced with something else.

If you really want all subdirectories replace the '*' with a call to 'find':

for dir in `find . -type d`; do echo $dir ; done;

Hi @jacaetevha,

In what situations it won't work? I ran the command:
for dir in *; do echo $dir ; done;
Without replace anything and it printed all first level subdirectories in macosx.

1) Your command echos files, as well as directories.
2) Your command doesn't deal with recursive subdirectories.

Perhaps you didn't intend for #2 above. If that's the case just add a -maxdepth argument to the find command:

for dir in `find . -type d -maxdepth 1`; do echo $dir ; done;

@jacaetevha I got your point
