Install · jaytail

jaytail is one executable with no runtime and no dependencies. The same download serves customers and anyone answering a jaytail ticket; a license is installed separately.

Linux and macOS

curl -fsSL https://jaytail.dev/install | sh

The installer needs no administrator rights and no terminal, so it also works inside a one-line command on a server. It reads the current version, the archive address and its SHA-256 from https://jaytail.dev/latest.json, downloads the archive from GitHub, verifies the checksum and installs:

What	Where
`jaytail`	`~/.local/bin` (override with `JAYTAIL_INSTALL_DIR`)
`jtail`, `jt`	the same directory, as links, unless another program already has the name
man page	`~/.local/share/man/man1/jaytail.1` (override with `JAYTAIL_MAN_DIR`)
bash, zsh, fish completion	under `~/.local/share` (zsh: add `~/.local/share/zsh/site-functions` to `fpath`)
license notices	`~/.local/share/doc/jaytail`

If ~/.local/bin is not on your PATH, the installer says so. Right after installing, run ~/.local/bin/jaytail or open a new terminal.

Windows

In PowerShell:

irm https://jaytail.dev/install.ps1 | iex

This installs into %LOCALAPPDATA%\Programs\jaytail (override with JAYTAIL_INSTALL_DIR), adds that directory to your user PATH, and creates jtail.cmd and jt.cmd unless the names are taken. Options need the script-block form:

& ([scriptblock]::Create((irm https://jaytail.dev/install.ps1))) -Minimal -NoPath -Completions

-Minimal installs the Minimal build, -NoPath leaves PATH alone, -Completions adds tab completion to your PowerShell profile.

Manual download

The download page lists every archive with its SHA-256. Check it before unpacking:

echo "<sha256>  jaytail-<version>-<target>.tar.gz" | sha256sum -c     # macOS: shasum -a 256 -c
tar -xzf jaytail-<version>-<target>.tar.gz
./jaytail-<version>-<target>/jaytail version

Each archive contains jaytail (jaytail.exe on Windows), the man page jaytail.1, shell completion scripts, README.md, LICENSE and THIRD-PARTY-LICENSES.md. Put the executable anywhere on your PATH.

Minimal build

The Minimal build is the same viewer without any network code: it cannot take part in transfers (send, receive, request). It is meant for environments where networking tools are not allowed. Install it with curl -fsSL https://jaytail.dev/install | sh -s -- --minimal, or with -Minimal on Windows. Every license works in both builds.

Updating

Run the installer again. It replaces the executable and keeps your licenses.

Uninstalling

Linux and macOS, with the default locations:

rm -f ~/.local/bin/jaytail ~/.local/bin/jtail ~/.local/bin/jt
rm -f ~/.local/share/man/man1/jaytail.1 ~/.local/share/man/man1/jtail.1 ~/.local/share/man/man1/jt.1
rm -rf ~/.local/share/doc/jaytail

Completion scripts are in ~/.local/share/bash-completion/completions, ~/.local/share/zsh/site-functions and ~/.local/share/fish/vendor_completions.d. On Windows, delete %LOCALAPPDATA%\Programs\jaytail and remove it from your user PATH. Licenses and jaytail's own state are kept in the directories listed under Licenses and activation; delete them too if you want nothing left.
