need help with creating loop and tar file

[marcmcconnell]

I have a question about a loop that I need to create.

I have about 15 directories each containing about 2000-4000 files. I have to create a loop that creates a tar file containing a maximum of 1000 files.

For example directory DIRA contains 2456 files. The loop would create DIRA1.tar containing files 1-1000 in the directory. DIRA2.tar would contain files 1001-2000. DIRA3.tar would contain files files 2001-2456. This would have to happen for all 15 directories (DIRB, DIRC etc..)

I obviously need some sort of a counter and maybe a while loop. Bit of a newbie with loops. Any ideas?

Hi

Bit of a newbie with loops.

No problem. You can help yourself without a proper counter.

-T, --files-from=F
get names to extract or create from file F

[ul]
[li]you list the files in temporary files ( with [tt]ls -1 > listfilename[/tt] )[/li]
[li]split it to to 1000 line chunks ( with [tt]split -l 1000 listfilename[/tt] )[/li]
[li]create archive for the content of each chunk file ( with [tt]tar -c -T chunkfilename archivefilename[/tt] )[/li]
[/ul]
