paccache: Set the number of package versions to keep.
$ paccache -rk ${num_versions}
try on your machine
The command "paccache -rk ${num_versions}" is used in the Arch Linux-based operating system to manage the package cache.
Here's a breakdown of each element:
- "paccache" is the name of the command utility used to manage the package cache.
- The "-rk" option is used to remove packages that are no longer installed and are older than the currently installed version. It stands for "remove" and "keep."
- "${num_versions}" is a variable that represents the number of versions that should be kept for each package. It is replaced with an actual number when the command is executed.
When this command is executed, it will remove all old versions of installed packages, leaving behind the specified number of most recent versions. This helps to free up disk space by deleting unnecessary package files while still keeping the most recent versions in the cache.
