# pacman --sync
> Arch Linux package manager utility.
> More information: <https://man.archlinux.org/man/pacman.8>.
- Install a new package:
`sudo pacman --sync {{package_name}}`
- Synchronize and update all packages (add `--downloadonly` to download the packages and not update them):
`sudo pacman --sync --refresh --sysupgrade`
- Update all packages and install a new one without prompting:
`sudo pacman --sync --refresh --sysupgrade --noconfirm {{package_name}}`
- Search the package database for a regular expression or keyword:
`pacman --sync --search "{{search_pattern}}"`
- Display information about a package:
`pacman --sync --info {{package_name}}`
- Overwrite conflicting files during a package update:
`sudo pacman --sync --refresh --sysupgrade --overwrite {{path/to/file}}`
- Synchronize and update all packages, but ignore a specific package (can be used more than once):
`sudo pacman --sync --refresh --sysupgrade --ignore {{package_name}}`
- Remove not installed packages and unused repositories from the cache (use two `--clean` flags to clean all packages):
`sudo pacman --sync --clean`
