dpkg -V

will look at all installed packages and report any missing or modified files. You can use this to build a list of missing binaries; dpkg -S will then allow you to determine which packages provide these binaries, and then

apt reinstall ...

will allow you to reinstall all the packages which aren’t complete.

This should do the trick:

dpkg -S $(dpkg -V | awk '/\/bin\// { print $2 }' | sort -u) |
awk -F: '{ print $1 }' |
sort -u |
xargs sudo apt reinstall

If you don’t want to check the changes before confirming them, add -y to the apt command (... apt reinstall -y).
