Useful Commands I'll Probably Forget

16 Jul 2025•1 min read

I regularly use the command line, and yet I'm googling unfamiliar commands more often than not... So I decided to keep them all in one place here.

Storage utilities

du -hd <depth> [target] | sort -h - get sorted disk usage (to see where space is being used the most) \

Archive

tar xvzf <archive.tar.gz> - unarchive .tar.gz

-x --extract = extract files from an archive
-v, --verbose = verbosely list files processed
-z, --gzip = gzipped files eg. for tar.gz packages
-f, --file ARCHIVE = use archive file or device ARCHIVE

VoidLinux

xbps-query -Rs <package> - query all packages
xbps-query -s <package> - query installed packages
sudo ln -s /etc/sv/<service> /var/service/ - enable service
sudo vkpurge rm all - remove unused kernel modules to free space
