Is there a way reverse of what mkdir -p option does?
I Use Ubuntu 18.04, 19.10
using #!/bin/bash
script how to remove the directories if they are empty from far end and stop at the directory having any file/files.
say.. I have created multiple directories with the below command
mkdir -p $HOME/.local/my/sub/directories/1/2/3
lateron during the time I have created lot of files in all directories starting from the directory "my to 1/2/3".
After some time I have deleted all the files in the directories "my", "directories", "1", "2", "3". Note that directory sub
is having some files..
mkdir -p
option will see if there are parent directories in the command mkdir -p $HOME/.local/my/sub/directories/1/2/3
and its safe.
Question: like above is there any command to see if the directories are empty and delete from far end and stop at directory sub
I mean $HOME/.local/my/sub
The reversal of the mkdir -p
command would be rmdir -p
. rmdir -p
will remove the folder structure up till the folder is not empty. You should be able to use rmdir
instead of mkdir
on your command:
rmdir -p $HOME/.local/my/sub/directories/1/2/3
You can also specify wildcards like if your $HOME/.local/my/sub/
contained like directories1
, directories2
and directories3
for example, it could be done as:
rmdir -p $HOME/.local/my/sub/directories*/1/2/3
or
rmdir -p $HOME/.local/my/sub/*/1/2/3
If any folder as it is removing them contains data or another folder you will receive an error message that the directory is not empty and stops.
rmdir: failed to remove directory '/home/user/.local/my/sub': Directory not empty
Hope this helps!
There are two ways I'd attempt this. The easy method is as follows:
# Command to return only empty directories in the current directory:
find . -type d -empty -print
Now on my version of Ubuntu, I can simply perform the following:
# Find empty files, and delete them:
find . -type d -empty -delete
Otherwise, you can create some script with a logic to count files in a directory, and delete them. Here is a starting point for counting files in sub-directories:
#!/bin/bash
for i in */ .*/ ; do
echo -n $i": " ;
(find "$i" -type f | wc -l) ;
done
