Lha commandline to skip .git subdirectory

thyslo · 10 September 2023, 13:58

I often use lha to back up a directory like

Code:

Lha -zerax a DH2:Backup-projectdir-2023-09-10.lha DH1:projects/projectdir

However, the problem is when the project directory contains a .git subdirectory. Because the .git subdirectory is large, the LHA takes a long time.

I don't need the .git directory in the backup file.

So, is there any command line option for lha to omit the .git subdirectory?

For quick adding files you can use the option -Qq.

For excluding file you can try "pattern matching" (see lha.guide) or maybe use a file list (-i) instead. I tried '~(.git)' but it works not as expected (no files added but directories will).

Thank you!

Too bad, '~(.git)' isn't working as it would be the natural solution for the problem.

So I maybe will choose a pragmatic solution: I do my lha backups anyway with a script 'dirupdate.rexx' that I wrote myself. I think I'll modify this script to temporarily move the .git directory to parent before lha runs, and then move it back afterwards (using the Rename command). I think, that'll do the trick.

It was the first time I tried pattern matching with LHA. So there might be a way that it works. Maybe someone knows. As already mentioned you can also use a file list (-i) as a source for LHA as an alternative. AmigaOS should be able to create such a list with its LIST command but any other tool (or OS) can be used too. Or your ARexx script perhaps?

Usually, thomas knows such things or the LHA author if you want to ask. At least I would before going the workaround way.

Perhaps the messages in this thread will help!

And indeed using a file list which also was shown in the two lines

Code:

list dh0:~(dirname2) lformat="*"%P%N*"" > T:backuplist.txt
lha -r -a -e -iT:backuplist.txt a dh1:archive.lha

from the other thread help me to achieve what I was looking for:-)

Thank you
