To include a report on the archive's integrity (checking for errors) while listing, use the test command: 7z t shaving.7z > shaving_integrity_report.txt 2. Full Technical Details
: 7z l shaving.7z > shaving_report.txt
This command creates a file named shaving_report.txt that includes: : The compression algorithm used (e.g., LZMA2).
💡 : If you are using a Linux-based system, you can discard standard messages and only report errors to a separate file by using 7z l shaving.7z 1> report.txt 2> errors.txt . Does 7z compress better than zip? - Microsoft Community Hub

: The final uncompressed size versus the archive size.
