Windows sigcheck equivalent in Linux
Checks installed files against package checksums.
sigcheck
debsums -s
sudo rpm -Va
sudo pacman -Qkk
Overview
What this command does
On Windows, "sigcheck" is used to verify installed package files. On Linux, the closest practical mapping shown here is "debsums -s". Checks installed files against package checksums. This reference is grouped under Security & Permissions → Integrity.
Windows → Linux context
What changes when you use this on Linux?
Equivalent task, different tool
Windows sigcheck maps to debsums for this task. Treat this as a workflow mapping rather than a character-for-character syntax translation.
Distribution details matter
The Debian/Ubuntu, Fedora and Arch rows are not identical. Use the row for your distribution instead of changing only the package-manager name in an example.
Elevated privilege appears in this workflow
At least one example uses sudo. Confirm the target path, device, service or package before running the elevated form; do not add sudo simply to bypass an unexplained permission error.
For the broader concept behind this mapping, read Linux permissions for Windows users.
