install — skill0

Install software any way the system allows. All x-cmd channels (x eget, x env use, x pixi) install into $HOME — no sudo, no system pollution. Only system package managers (x apt, x brew, …) touch the OS and may need sudo.

Choose a channel

Channel	Best for
x install	Recommended. One front door — lists every method for a tool, picks the best
x eget	Latest binaries straight from upstream repos (GitHub / Codeberg releases)
x env use	Runtimes & tools hosted by x-cmd (wraps x pkg use)
x pixi	conda / pixi-ecosystem packages
x apt/brew/dnf/pacman	System package managers (may need sudo)

Prerequisites

x-cmd provides every channel above:

eval "$(curl https://get.x-cmd.com)"

x install — the recommended front door

Every tool ships several install paths; x install auto-picks the best one. All forms below are non-interactive (agent / CI safe):

x install bun                            # install — auto-picks the best method
x install --printinfo ripgrep            # list every install method first (read-only)
x install --withtool brew jq             # force a manager; or prefix form: brew/jq
x install --sys bun                      # system package manager only
x install --printcmd bun vim             # preview the command, don't run
x install --env                          # platform / arch / distro probe
x install --available-tool --installed   # which package managers exist here

Discover what's installable

x install --ls emits a TSV of every indexed tool — grep / awk it offline:

x install --ls --tsv | head -1                  # header
x install --ls --tsv | grep -i json             # search by keyword
x install --ls --tsv | awk -F'\t' '$3=="Rust"'  # filter by language
x install --search http                         # aggregate search across registries

TSV columns: name category lang source desc_cn desc_en binlist rule other.

Change mirrors (faster downloads)

Redirect a slow system package manager to a faster / local mirror. Each has mirror ls (list options) and mirror set <code> (apply, non-interactive):

x brew mirror ls          # list: official, ali, tuna, bfsu, ustc, sjtu, ...
x brew mirror set tuna    # apply Tsinghua mirror
x apt mirror set tuna     # same shape on Debian / Ubuntu (also dnf, pacman)

Requires the target package manager to be installed.
