Will try to fix the more-info issue later

[reinhart1010]

Hello! I've noticed something unusual when checking this PR:

• The page pages.id/common/clang.md is outdated, based on the command contents itself.
• The page pages.id/common/g++.md is outdated, based on number of commands.

Is this intended? If so, just ignore this comment. Otherwise, please double-check the commits.

If you fix this, the PR is good to go

Done
