How to Get 7-Zip Hash Command Output on One Line?

[raywood]

I am using 7-Zip in Linux, but will be happy to get clues from the comparable Windows command.

I have a file named 1310. To hash that file, I enter this;

7zz h -scrcblake2sp /path-to-file/1310

That gives me a boatload of material, like this:

Everything is Ok*

All I want is the one line that mentions the file's name, size, and hash. It's the one that looks like this:

e1e24f94859d2373f43edb4ffab9dadfe1c677f6a68b258af0ae9807cb74eb13 525465333 1310

To get that one line of output per file, is there some 7-zip option that I am overlooking?

I could use the Linux findstr command to pull out that one line, if I were doing this only for file no. 1310; but in fact I expect to do it, at times, for long lists of files, sometimes for all files in a folder or drive. My Linux scripting abilities are not remotely at the level to know how to use the filename as a variable in a loop.

Suggestions?

Very helpful. Thank you.

Is there a way to include timestamp (i.e., each file's modification date and time) in the output?

Timestamps in that list are not implemented.
