Psst. Open beta.
Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:
- » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
- » If you wish to use your user account, you will probably need to reset your password.
Terminal - Commands tagged pacman - 7 results
Alternative1 (grep support):
pacman -Ss python | paste - - | grep --color=always -e '/python' | less -R
Alternative2 (eye-candy, no grep):
pacman --color=always -Ss "python" | paste - - | less -R
in ~/.bashrc:
pkg-grep() { pacman -Ss "$1" | paste - - | grep --color=always -e "${2:-$1}" | less -R ; }
pkg-search() { pacman --color=always -Ss "python" | paste - - | less -R; }
In this example I am returning all the files in /usr/bin that weren't put there by pacman, so that they can be moved to /usr/local/bin where they (most likely) belong.
-Qdt Lists dependencies/packages which are no longer required by any packages
-q Output only package name (not the version number)
-R Remove package(s)
Rest is self-explanatory.
I just started out with Arch - so if there is any better/standard method to achieve the same - please suggest.
This, like the other commands listed here, displays installed arch packages. Unlike the other ones this also displays the short description so you can see what that package does without having to go to google. It also shows the largest packages on top. You can optionally pipe this through head to display an arbitrary number of the largest packages installed (e.g. ... | head -30 # for the largest 30 packages installed)
M is size in megabytes, man expac to see other sizes
%m is install size
%k is download size
This one-liner will output installed packages sorted by size in Kilobytes.
