Anyone fancy giving me some scripting help?

I have a Linux machine where I have a lot of folders within a folder and I need to make a tar.gz of each of the subfolders and then delete the original subfolder Something like
Code:
Folder
    Sub1
       File1
       File2
       .
       .
       FileN
    Sub2
       File1
       File2
       .
       .
       FileN


After the script I end up with
Code:
Folder
    Sub1.tar.gz
    Sub2.tar.gz


Eventually, I'll probably tar.gz the resulting files as well, ending up with only one file.
I tried yesterday to select all the folders, right-clicking and selecting Create archive. After it had run for about 16 hours, it had done about 2/3 of the selected folders. Seems it will tar.gz one folder, add it to the finished result, tar.gz the next folder, untar the result before adding the second folder. As the tar-file grows, it will take longer and longer time to add one folder. When I stopped it, the resulting file was 12Gb and 178k files...

I think this script will be quite simple, butI'm not very adept at scripting... smile

How about this?

Code:

#!/bin/sh

for subdir in *
do
        if [ -d "$subdir" ]
        then
                tar cvfz  "$subdir".tar.gz "$subdir"/*
                #rm -r "$subdir"
        fi
done


(commented out the rm -r - only uncomment when you are sure everything works the way you want!)

Thanks, Julf.

That worked. I removed the verbose output from tar and added a line above it instead (echo "Archiving $subdir"). It got a bit old watching 170k+ lines scroll across the screen... smile

Ah, yes, should have removed that after testing...

Note that the script is not very robust - it is a typical 2-minute off-the-cuff thing...

Still, it worked for what I needed.

It looks more robust than what I'd have suggested:
Quote:

find . -maxdepth 1 -type d | xargs -I% tar --remove-files cf %.tgz %/*

gzipping a tar file that contains only other gzipped files is going to gain you very little beyond using up some CPU time.

You'll probably actually lose a miniscule amount of hard drive space due to the overhead of the zipping program, but you will have a cleaner-looking directory tree.

To some of us OCD types, that is worthwhile. smile

You won't have a cleaner tree by doing the extra gzip. You can just have the top level file be a tar file, rather than a gziped tar file.

(you don't really have the equivalent of a tar file in the Windows world, a tar file is kind of like a zip file but with no compression)

I may not gain anything by gzipping the resulting files, but it's easier to just select all the files and select Create archive than to do the commands in the shell. I don't really have much problems using the shell, but my collegues on the opposite crew aren't very Linux-savvy.

Can you not just do a tarred but not zipped archive via the same route ?

If you mean using the file browser? Don't know. Maybe by changing the extension when inputting the file name, but it works this way as well. That's good enough for me... smile
