Question - how to use tar to compress multiple top level folders recursively into discrete zip files

Does it matter, the tar process is tar?

But osx is likely where this would be run from.

Then the "simple way" with some semi-obvious assumptions...

for i in $(ls); do tar -czvf $i.tgz $i; done

OS does not, shell does.

Assuming BASH for launching tar...

Then the "complex way"...
for i in compress compress1 compress2; do tar -czvf $i.tgz $i; done

That I think would require me to fill out the tar command on a forever ongoing process. Hoping to be able to just target the --- folder root for.

Or another way....

for i in $(ls -r | grep compress); do tar -czvf $i.tgz $i; done

Should be easy to do, you just have to define what makes the target folder obviously the target and write the bit in the $() to return that and away you go.

Because I was going to write a cmd for loop for you if it were Win, and I was going to pass if it were *nix.

Well of the --- folder never changes, but the content beneath it does, that would be what I would target.

I'm trying to resolve our user base breaking our backups by have file paths longer than 255 characters, which the simplest way I can think of is to just compress everything in --- folder.

It's the shell, not the OS, that determines the looping structure. PowerShell on Linux is the same as on Windows. Bash on Windows is the same as on Linux.

I don't follow your - - - naming scheme. Can you explain differently?

Yeah the spacing didn't copy over from mobile.

Essentially it's

Root folder

sub folder
- child folder
different sub folder from root
- child folder

Okay so this is the next annoyance with this, I am getting the entire parent folder up until the target folder in the compressed file.

IE: compressed-folder.tar contains

Share Name
- Sub-Parent-Folder
  - Next-Level-Parent-Folder
    - Target-Folder
      . . . . all of the files and sub-folders

Anyway to have tar just target the Target-Folder that is on an SMB share, compress that specifically (and it's children to a single file) so I can then move that compressed file without all of the overhead folder structure?

DustinB3403

I suppose I could mount each and every Target-Folder but that seems completely counter intuitive and a massive effort. . .

Why not specify /path/to/targetfolder/

I'm not following what you mean.

How I'm currently doing this is tar -zcvf Compressed.zip /Volumes/Parent/Child/Target-folder/

Edit:

And I get everything in the path /Volumes/Parent/Child/Target-folder/ so the compressed file, when decompressed is /Volumes/Parent/Child/Target-Folder/some-stuff

What I want is just Target-Folder and it's contents, not the parent folder path.

Supposedly tar -C /Volumes/Parent/Child/Target-folder -cvf Compressed.zip SelectedDirectory works. . . let me test that.

Okay so that does work, just is a pain in the rear to have to do manually.
