7-Zip command-line switch

Question

Is there a 7-Zip command-line switch that prevents the filenames from echoing to the screen as they are added to the archive?

Answer 1

If it doesn't have one, you can still redirect the output using > into a file, then deleting the file afterwards. If you are on *nix, you can redirect into /dev/null.

Edit

In MS-DOS and cmd.exe you can redirect into NUL, instead of a file. Thanks to agnul for this hint.

Answer 2

Not built in, but if you add

<7z command here> 2>&1 NUL

to the end of your command-line, it will redirect all the output into the null device and stops it echoing to the screen. This is the MS-DOS equivalent of

2>&1 /dev/null

in Linux and Unix systems.

Answer 3

AFAIK, there is not a switch for that, but you could hide the output redirecting it to a file, for example (DOS batch):

7z.exe ... normal parameters > DumpFile.txt

This way all the output ends in DumpFile.txt and not on the screen.
