Extracting a 7-Zip file "silently" - command line option

I just came across this when searching for the same, but I solved it myself! Assuming the command is processed with Windows / DOS, a simpler solution is to change your command to:

7z.exe -o some_dir x some_archive.7z > nul

That is, direct the output to a null file rather than the screen.

Or you could pipe the output to the DOS "find" command to only output specific data, that is,

7z.exe -o some_dir x some_archive.7z | FIND "ing archive"

This would just result in the following output.

Creating archive some_archive.7z

or

Updating archive some_archive.7z**

---

My final solution was to change the command to

... some_archive.7z | FIND /V "ing  "

Note double space after 'ing'. This resulted in the following output.

Updating some_archive.7z


Everything is Ok

This removes the individual file processing, but produces a summary of the overall operation, regardless of the operation type.

One possibility would be to spawn the child process with popen, so its output will come back to the parent to be processed/displayed (if desired) or else completely ignored (create your popen object with stdout=PIPE and stderr=PIPE to be able to retrieve the output from the child).
