In https://wiki.archlinux.org/title/pacman#Querying_package_databases, there’s this:
Sometimes,
-s
’s builtin ERE (Extended Regular Expressions) can cause a lot of unwanted results, so it has to be limited to match the package name only; not the description nor any other field:
$ pacman -Ss '^vim-'
Running pacman -Ss '^vim-'
returns a lot of hits but …
pacman -Ss '^tor-'
gives 0 hits
whereas pacman -Ss '^tor'
gives 5 hits including simply community/tor
. Shouldn’t community/tor
also have been found with pacman -Ss '^tor-'
?
I’m even more confused by the output of pacman -Ss '^qt-'
(lines numbered for ease of reference):
~ $ pacman -Ss '^qt-' | nl
1 extra/kdsoap 2.0.0-1
2 Qt-based client-side and server-side SOAP component
3 extra/kwayland 5.89.0-1 (kf5)
4 Qt-style Client and Server library wrapper for the Wayland libraries
5 extra/libaccounts-qt 1.16-3
6 Qt-based client library for accessing the online accounts database
7 extra/qt-gstreamer 1.2.0-4
8 Qt bindings for GStreamer
9 community/ksnip 1.9.2-1 [installed]
10 Qt-based screenshot tool that provides many annotation features
11 community/python-qtconsole 5.2.1-2
12 Qt-based console for Jupyter with support for rich media output
13 community/qjournalctl 0.6.3-2
14 Qt-based graphical user interface for the journalctl command
15 community/qt5-gsettings 1.3.0-1 (liri)
16 Qt-style wrapper for GSettings
17 community/sigdigger 0.1.0-2
18 Qt-based digital signal analyzer, using Suscan core and Sigutils DSP library
~ $
The names in lines 1, 3, 9, 17 (and 13 if one doesn’t allow fuzzy search) don’t have qt
in them.
So I’m getting the impression that flanking a string with ^
and -
doesn’t always work to yield results in which the string is in the name. Am I wrong?
