Without doing stdout redirection. Is it possible to have a silent run of 7za?

Can you mark the correct answer? – ceztko Apr 02 '20 at 16:18

Yes that is possible.
Just add -y -bsp0 -bso0 to your command line. Those switches will disable progress, output reporting & assume yes answer to any possible questions, while still showing you any errors (which is perfect for cron usage).
Example:
7za a result.tar.7z -y -bsp0 -bso0 example.tar
From 7za --help
:
-bs{o|e|p}{0|1|2} : set output stream for output/error/progress line
-y : assume Yes on all queries
Tested to work on 7z version: 16.02.
Note, that version 9.20 bundled with some older OS (you can check your version by running 7za i
) doesn't support that feature. You can download latest statically linked binaries at the official website.

Looking at the output of 7za --help
, I don't think so.
Is there any particular reason why you don't want to just do 7za a archive.7z files > /dev/null
?

5@pavium True, but since there doesn't seem to be an option to run 7za in quiet mode, it looks like the best option available. – developmentalinsanity Jan 31 '10 at 12:16
Side note: xz
compressor uses the same algorithm 7Zip does (LZMA) but in a way similar to gzip
or bzip2
making it compatible with standard UNIX tools.
You can compress a file:
$ xz file.ext $ ls file* file.ext.xz
Or use it to compress a directory with tar
:
$ tar cJf dir.tar.xz dir/ $ ls -d dir* dir dir.tar.xz

Maybe you can wrap 7za in a script, so that the place that calls it doesn't need the redirection?
