create script in /usr/bin called pacclean?

xaer0knight · 2011-05-15 04:32:00

#!/bin/bash

su -c 'pacman -Qdt'
su -c 'pacman -Scc && pacman-optimize'
yaourt -Syua

this script was created to show
1) To list all packages no longer required as dependencies (orphans) (pacman -Qdt)
2) Clean the package cache of packages that are not currently installed (/var/cache/pacman/pkg) and removes all packages from the cache. (pacman -Scc)
3) Improving database access speeds reduces the time taken in database-related tasks, e.g. searching packages and resolving package dependencies. (pacman-optimize)
4) You can update your system including AUR packages (yaourt -Syua)

I think this is a good script i think, but is there a way to streamline it by not entering my password over 3 times? this script i created in /usr/bin and called it pacclean which i made it executable.

Do you really need a password for 'pacman -Qdt'? There are other ways to run pacman w/o entering the password e.g. visudo + NOPASSWD.
'pacman -Scc' will remove all packages from the cache, not only those that aren't installed - point 2 is not clear about this.

I think you still need to 'chmod +x pacclean' to make it executable. You placed it in a folder that's in your $PATH, so you can call it from every folder, just like cp, mv etc.

Why not just create an alias

alias paclean='sudo pacman -Qdt && sudo pacman -Sc && sudo pacman-optimize'

And as karol mentioned, note the difference between -Sc and -Scc

It would be nice to have a way of acting on the output of 'pacman -Qdt' before 'sudo pacman -Sc' :-)

I have a script that has much the same concept as this one, but much longer. I'm sure I posted it in this forum before, but as it's changed a little recently, I'll repost here. It may give someone some ideas for how they'd like to wrap pacman themselves, or some coding style thoughts. I install this in /usr/local/sbin/pu and add that same path to sudoers with NOPASSWD set. Note that you don't have to run it with sudo yourself, as it will detect if you are not root and re-run itself in sudo for you if not. Note that this will produce a large amount of noise output on the first run, as the saved state data (/var/lib/pu) won't be populated yet, and so all the comparisons from last run to now will run as if everything in the world is brand new.

Since this script calls yaourt, it seems worthwhile to point out that yaourt -Qdt prints the output of pacman -Qdt and then offers to remove the listed packages, should the user wish to do so. I just use aliases for these:

alias pacor='yaourt -Qdt' # List (and remove) orphaned packages
alias paccl='yaourt -Sc' # Clean unused packages from PacMan cache
alias pacem='yaourt -Scc' # Empty PacMan cache

I don't like the idea of completely automating something that digs around my system, or eliminates something I just might need later.

thanks guys for all your help. ill try em all

this works well with Yapan (Yet Another Package mAnager Notifier.)
Note: This work well with Yapan but the only issue is that su -c 'pacman-optimize' command in your /usr/paclean will ask for your password.

1. Make a file called /usr/paclean

 #sudo nano /usr/paclean

Add the following code to /usr/paclean:

 #!/bin/bash

yaourt -Qdt
yaourt -Scc
yaourt -Syua
su -c 'pacman-optimize'

2. The make /usr/paclean executable by

sudo chmod +x /usr/paclean

3. Install Yapan (Yet Another Package mAnager Notifier.) In your terminal program type:

 #yaourt -S yapan

4. In Yapan's settings, under the Package Manger Tab, change the following :
Synchronize: yaourt -Syy --aur --dbpath /tmp/yapan/ &> /dev/null
List package to update: yaourt -Qqu --aur --dbpath /tmp/yapan/
Update: /usr/paclean --dbpath /tmp/yapan/
