Note
These are notes taken from Luke Smith’s Video https://youtu.be/-dEuXTMzRKs
Installing a package**
sudo pacman -S emacs
To Updating database
sudo pacman -Syu
-S = sync package to remote repositories
-Sy = Just sync
-u = update a program
double checks sync and install updates
sudo pacman -Syyu
‘w’ flags download the updates in the background and will not install it.
sudo pacman -Syyuw
In debian based distros you get these apt-get update && apt-get upgrade
which is equivalent to these in arch
pacman -Sy && pacman -Su
but you can run this as one like this pacman -Syu
To search for programs in remote repositories
pacman -Ss emacs
To search for programs in local repositories
pacman -Qs emacs
Uninstalling packages
pacman -R vidir - Just remove the program
pacman -Rs vidir - To remove with dependancie
pacaman -Rn vidir - To remove with system config (not config (dotfiles))
# So the best way to uninstall is using
pacman -Rns vidir
# To remove package with all dependant packages [be cautious here]
pacman -Rsc vidir
# but if need to delete without removing dependant packages
pacman -Rdd vidir
Listing out programs
`pacman -Q` - List out all packages installed in system
`pacman -Qe` - List out user explicitely installed packages
`pacman -Qn` - List out programs installed from main repositories
`pacman -Qm` - List out programs installed from AUR
Extra Utilities
`pacman -Qdt` - No longer needed programs (orphaned packages)
Configuring /etc/pacman.conf
uncomment any flags you want to use by removing # hashtags
Color - Enable coloring
CheckSpace - Enable checkspacing
ILoveCandy - Enable pacman ascii animation
VerbosePackageList - Enable detailed information about package changes
IgnorePkg = libseccomp - To stop a program from being upgraded
sudo pacman -Syu --ignore=vlc - To ignore temporarily
HoldPkg = Glibc - To hold a package to install
To downgrad any packages
`pacman -U /var/cache/pacman/pkg/package-old_version.pkg.tar.type`
-U is for installing from local file
You can change mirrorlist from here
`/etc/pacman.d/mirrorlist`
Cleaning Up
When you update packages to newer version older version of packages are still there.
SO if you want to clear out all these older packages from caches do this.
df -h - to check disk size
pacman -Sc - To clear caches
WARNING: You upcan remove pacman caches with this command sudo pacman -Sc but
it also clear the caches of your installed packages which are needed when
package update doesnt work and you have to downgrade until the issue is fixed.
Thats not a big disaster because you can easily downgrade a package using Arch repo.
But be careful before you use this. And DO NOT use this oftenly. ONLY once in a year or so.
