If using RAR on Ubuntu or Centos, this is the command for compressing a single folder (with subfolders inside), or is the command for compressing all folders inside a directory in a single archive:
rar a -m0 -r name.rar
where
-m0 is level of compression
-r recursive mode
But if I want to compress each folder? Which commands to use?
I want preserve the directory tree on compressing each folder.
I tried also this command,
for folder in */; do echo rar a -m0 -r "${folder%/}.rar" "$folder"; done
but it gave me no action, but in terminal appears so:
user@hppro ~
$ ls -l
total 3
drwxr-xr-x+ 1 user None 0 Aug 2 03:17 abcd_dir
drwxr-xr-x+ 1 user None 0 Aug 2 03:18 defgh_dir
-rwx------ 1 user None 86 Dec 24 2020 blahfile
user@hppro ~
$ for folder in */; do echo rar a -m0 -r "${folder%/}.rar" "$folder"; done
rar a -m0 -r abcd_dir.rar abcd_dir/
rar a -m0 -r defgh_dir.rar defgh_dir/
user@hppro ~
$
The parameter substitution ${folder%/} serves to strip out the "/" at the end of the folder name. But this code does not work.

P.S: I use Centos or Ubuntu not Windows.
