lha return codes

[orange]

what does "lha failed returncode 20" and similar mean?

[orange]

lha fails on some archives only, executing script, with code 10 or 20.
seems that 20 happens when filename contains nonstandard-ASCII char. but what is 10?
strangely, with error 10, it fails only in script.
thanks.

10 is a script failure.  The codes are not clearly defined in the manual.  Do you have a manual?  Can you list the script here?

its very simple, albeit long, script:
"

makedir RAM:lhat
lha x -a -r -e -x -M -m -n -q  "PC:lha/dir1/archive1.LHA" RAM:lhat/
lha a -a -r -e -x -M -n -q -z  "PC:lha_out/dir1/archive1.LHA" RAM:lhat/
delete  RAM:#? ALL FORCE QUIET

...
"
er, didn't know there was difference between cli and shell, think this is from cli.

edit: it seems there's a problem in filename. it says "Unable to open output file". is there a way to use utf-8 in cli?

I'm trying to unarchive each .lha and then repack it in .lha but with zero compression. Later I can pack them all again with 7z, for eg., to achieve (much) higher compression ratio. I've written a perl script that creates this script for every .lha. Because some archives are inside archives, I've done this recursively to second level. But there's a lot of filenames with nonASCII.

10 and 20 mean nothing. They are just standard AmigaDOS return codes for error resp. failure. You have to read the error messages Lha prints out. Don't use >nil: or similar to hide the messages if you need them.

Thanks Thomas.

After doing some tests, I think the aminet archive could be reduced in size to less than 50% with this method.
