sample

gup updates binaries installed with go install, running the updates in parallel instead of one at a time.

gup also manages the tools under $GOPATH/bin ($GOBIN): list and check what is installed, remove binaries, export/import the set to reproduce the same tool set on another machine, and migrate them into a different $GOBIN. Runs on Windows, macOS, and Linux.

If you are using oh-my-zsh, then gup has an alias set up. The alias is gup - git pull --rebase. Therefore, please make sure that the oh-my-zsh alias is disabled (e.g. $ \gup update).

Supported OS (unit testing with GitHub Actions)

  • Linux
  • Mac
  • Windows

How to install

gup is already available via winget, mise, and nix in addition to go install and Homebrew.

Use "go install"

If you do not have the Go development environment installed on your system, please install it from the official website.

go install github.com/nao1215/gup@latest

Use homebrew

brew install nao1215/gup

Use winget (Windows)

winget install --id nao1215.gup

Use mise-en-place

mise use -g gup@latest

Use nix (Nix profile)

nix profile install nixpkgs#gogup

Install from Package or Binary

The release page contains packages in .deb, .rpm, and .apk formats. gup command uses the go command internally, so the golang installation is required.

Verifying release integrity

Every release ships supply-chain metadata so you can verify what you download:

  • Signed checksums — checksums.txt is signed with cosign (keyless), producing checksums.txt.sig and checksums.txt.pem.
  • SBOM — an SPDX Software Bill of Materials is attached to each release archive.
  • Build provenance — SLSA build provenance is attested via GitHub OIDC.

Verify the signed checksums (then check your archive against checksums.txt):

cosign verify-blob \
  --certificate checksums.txt.pem \
  --signature checksums.txt.sig \
  --certificate-identity-regexp 'https://github.com/nao1215/gup/\.github/workflows/release\.yml@refs/tags/.*' \
  --certificate-oidc-issuer 'https://token.actions.githubusercontent.com' \
  checksums.txt
sha256sum --check --ignore-missing checksums.txt

Verify the build provenance of a downloaded artifact with the GitHub CLI:

gh attestation verify gup_<version>_<os>_<arch>.tar.gz --repo nao1215/gup

How to use

Check the gup version

Print the version with either the version subcommand or the top-level --version/-V flag.

$ gup --version
$ gup version

Update all binaries

gup update updates every binary under $GOBIN, in parallel.

update

Update the specified binary

If you want to update only the specified binaries, you specify multiple command names separated by space.

$ gup update subaru gup ubume
update binary under $GOPATH/bin or $GOBIN
[1/3] github.com/nao1215/gup (v0.7.0 to v0.7.1, go1.20.1 to go1.22.4)
[2/3] github.com/nao1215/subaru (Already up-to-date: v1.0.2 / go1.22.4)
[3/3] github.com/nao1215/ubume/cmd/ubume (Already up-to-date: v1.4.1 / go1.22.4)

Exclude binaries during gup update

If you don't want to update some binaries simply specify binaries which should not be updated separated using ',' without spaces as a delimiter. Also works in combination with --dry-run

$ gup update --exclude=gopls,golangci-lint    //--exclude or -e, this example will exclude 'gopls' and 'golangci-lint'

Update binaries with @main, @master, or @latest

If you want to control update source per binary, use the following options:

  • --main (-m): update by @main (fallback to @master)
  • --master: update by @master
  • --latest: update by @latest

The selected channel is saved to gup.json and reused by future gup update runs.

$ gup update --main=gup,lazygit --master=sqly --latest=air

List up command name with package path and version under $GOPATH/bin

list subcommand print command information under $GOPATH/bin or $GOBIN. The output information is the command name, package path, and command version. list

Remove the specified binary

If you want to remove a command under $GOPATH/bin or $GOBIN, use the remove subcommand. The remove subcommand asks if you want to remove it before removing it.

$ gup remove subaru gal ubume
gup:CHECK: remove /home/nao/.go/bin/subaru? [Y/n] Y
removed /home/nao/.go/bin/subaru
gup:CHECK: remove /home/nao/.go/bin/gal? [Y/n] n
cancel removal /home/nao/.go/bin/gal
gup:CHECK: remove /home/nao/.go/bin/ubume? [Y/n] Y
removed /home/nao/.go/bin/ubume

If you want to force the removal, use the --force option.

$ gup remove --force gal
removed /home/nao/.go/bin/gal

In non-interactive execution (when stdin is not a TTY, e.g. CI or a pipe), gup remove no longer blocks waiting for confirmation. It fails fast with a clear message; pass --force to remove without confirmation.

Check if the binary is the latest version

If you want to know if the binary is the latest version, use the check subcommand. check subcommand checks if the binary is the latest version and displays the name of the binary that needs to be updated.

$ gup check
check binary under $GOPATH/bin or $GOBIN
[ 1/33] github.com/cheat/cheat (Already up-to-date: v0.0.0-20211009161301-12ffa4cb5c87 / go1.22.4)
[ 2/33] fyne.io/fyne/v2 (current: v2.1.3, latest: v2.1.4 / current: go1.20.2, installed: go1.22.4)
   :
[33/33] github.com/nao1215/ubume (Already up-to-date: v1.5.0 / go1.22.4)

If you want to update binaries, the following command.
           $ gup update fyne_demo gup mimixbox

Like other subcommands, you can only check the specified binaries.

$ gup check lazygit mimixbox
check binary under $GOPATH/bin or $GOBIN
[1/2] github.com/jesseduffield/lazygit (Already up-to-date: v0.32.2 / go1.22.4)
[2/2] github.com/nao1215/mimixbox (current: v0.32.1, latest: v0.33.2 / go1.22.4)

If you want to update binaries, the following command.
           $ gup update mimixbox

Quiet output for large tool sets

check and update print every binary by default, which is noisy when you have many tools installed. Pass --quiet (-q) to suppress the up-to-date lines and show only the binaries that were updated (or have an update available) plus failures, followed by a one-line summary. Errors are always written to STDERR, so they stay visible. When --json is also given, --quiet is ignored and the full JSON array is printed.

$ gup update --quiet
github.com/nao1215/gup (v0.7.0 to v0.7.1)
gup: 1 updated, 8 up-to-date, 0 failed

$ gup check -q
github.com/nao1215/gup (current: v0.7.0, latest: v0.7.1 / go1.22.4)

If you want to update binaries, run the following command.
           $ gup update gup
gup: 1 update available, 8 up-to-date, 0 failed

Machine-readable JSON output (for scripting / CI)

list, check, and update accept --json, printing a JSON array instead of the human-readable output (which stays the default).

$ gup check --json
[
  {
    "name": "gup",
    "import_path": "github.com/nao1215/gup",
    "module_path": "github.com/nao1215/gup",
    "channel": "latest",
    "current_version": "v1.0.0",
    "latest_version": "v1.1.0",
    "current_go_version": "go1.22.4",
    "installed_go_version": "go1.22.4",
    "status": "update-available"
  }
]

Each element has these fields: name, import_path, module_path, channel (latest/main/master), current_version, latest_version (empty for list), current_go_version, installed_go_version, status, and error (omitted when absent). status is installed (list), up-to-date, update-available (check), updated (update), or error.

The array is always valid JSON, including partial failures (those packages get "status": "error"; error detail also goes to STDERR so STDOUT stays pure JSON). Exit codes are unchanged—check reporting update-available still exits 0.

Export／Import subcommand

Use export/import when you want to install the same Go binaries across multiple systems. gup.json stores import path, binary version, and update channel (latest / main / master). import installs the exact version written in the file.

{
  "schema_version": 1,
  "packages": [
    {
      "name": "gal",
      "import_path": "github.com/nao1215/gal/cmd/gal",
      "version": "v1.1.1",
      "channel": "latest"
    },
    {
      "name": "posixer",
      "import_path": "github.com/nao1215/posixer",
      "version": "v0.1.0",
      "channel": "main"
    }
  ]
}

By default:

  • gup export writes to $XDG_CONFIG_HOME/gup/gup.json
  • gup import auto-detects config path in this order:
    1. $XDG_CONFIG_HOME/gup/gup.json (if exists)
    2. ./gup.json (if exists)

You can always override the path with --file.

※ Environments A (e.g. ubuntu)
$ gup export
Export /home/nao/.config/gup/gup.json

※ Environments B (e.g. debian)
$ gup import

export can print config content to STDOUT by --output. import can read a specific file by --file.

※ Environments A (e.g. ubuntu)
$ gup export --output > gup.json

※ Environments B (e.g. debian)
$ gup import --file=gup.json

Migrate binaries to a new $GOBIN

gup migrate BEFORE_PATH AFTER_PATH [BINARY...]

gup migrate reinstalls the Go binaries under BEFORE_PATH into AFTER_PATH, using the exact import path@version recorded in each binary's build info (it never silently upgrades to @latest). Internally it just sets GOBIN to AFTER_PATH and runs the normal go install path, so the binaries are rebuilt with the Go toolchain currently in use.

Why this is useful (e.g. with mise)

When you manage Go with mise, updating Go can change the real path of $GOBIN per Go version. As a result, tools you installed under the previous $GOBIN are no longer visible to the new Go. gup migrate lets you reinstall the same Go tool set from the old $GOBIN into the new one:

# Reinstall every go-install tool from the old GOBIN into the new GOBIN
$ gup migrate ~/.local/share/mise/installs/go/1.24.0/bin ~/.local/share/mise/installs/go/1.25.0/bin

# Migrate only specific binaries
$ gup migrate /old/gobin /new/gobin gopls air

migrate is add-only:

  • It never deletes or cleans up files in AFTER_PATH.
  • Binaries that already exist in AFTER_PATH are skipped by default. Use --force to reinstall over them.
  • AFTER_PATH is created automatically when it does not exist.
  • BEFORE_PATH and AFTER_PATH must be different directories.

Binaries whose import path or version cannot be resolved, and development builds (devel / (devel)), are skipped instead of being upgraded, so local or non-reproducible builds are never broken.

Supported flags: --dry-run (-n), --notify (-N), --jobs (-j), --force.

Generate man-pages (for linux, mac)

man subcommand generates man-pages under /usr/share/man/man1.

$ sudo gup man
Generate /usr/share/man/man1/gup-bug-report.1.gz
Generate /usr/share/man/man1/gup-check.1.gz
Generate /usr/share/man/man1/gup-completion.1.gz
Generate /usr/share/man/man1/gup-export.1.gz
Generate /usr/share/man/man1/gup-import.1.gz
Generate /usr/share/man/man1/gup-list.1.gz
Generate /usr/share/man/man1/gup-man.1.gz
Generate /usr/share/man/man1/gup-migrate.1.gz
Generate /usr/share/man/man1/gup-remove.1.gz
Generate /usr/share/man/man1/gup-update.1.gz
Generate /usr/share/man/man1/gup-version.1.gz
Generate /usr/share/man/man1/gup.1.gz

Generate shell completion file (for bash, zsh, fish, PowerShell)

completion prints completion scripts to STDOUT when you pass a shell name. To install completion files into your user environment for bash/fish/zsh, use --install. For PowerShell, redirect the output to a .ps1 file and source it from your profile.

$ gup completion bash > gup.bash
$ gup completion zsh > _gup
$ gup completion fish > gup.fish
$ gup completion powershell > gup.ps1

# Install files automatically to default user paths
$ gup completion --install

Desktop notification

If you use gup with --notify option, gup command notify you on your desktop whether the update was successful or unsuccessful after the update was finished.

$ gup update --notify

success warning

Disable colorized output

gup colorizes its output by default. To turn colors off, pass --no-color or set the NO_COLOR environment variable to a non-empty value (following the NO_COLOR convention). This is useful when piping output, in CI logs, or with NO_COLOR set globally.

$ gup update --no-color
$ NO_COLOR=1 gup update

Benchmark

gup runs updates in parallel, so it finishes faster than tools that update binaries one at a time. Updating 9 binaries that each had a newer version available:

Tool Strategy Time
gup update parallel 0.7s
go-global-update sequential 2.9s
go install loop sequential 2.9s

Measured on AMD Ryzen AI Max+ 395 (32 cores) / 64 GB RAM / Ubuntu 26.04 / go 1.26.4, median of 5 runs with a warm Go module cache. Times depend on each binary's build time and your CPU.
