What's the difference between apt-get and updatedb commands in terminal

[adam20]

Not quite sure what the difference is between the 2

[Jonathan Precise]

apt-get

installs/upgrades packages.

updatedb

updates the slocate database.

[Elfy]

apt-get is the package handler - used to install packages

the updatedb command updates the database used by locate

They are completely different things

[Elfy]

...

updatedb

just updates a list of the programs that can be run by program-name instead of /path/to/program-name.

No - it does more than that

locate will find more than just program names.

Check out updatedb.conf

cat /etc/updatedb.conf

You'll see there it keeps much more in the database, in my case I mount all my multimedia in /mnt mountpoints - I can use locate on those files too.

updatedb

updates the slocate database.

Jon, on my Lubuntu 13.04, `man` say that /var/lib/mlocate/mlocate.db is the database.
BTW, very nice apt-get tutorial
