= Gerrit Code Review - Command Line Tools

== Client

Client commands and hooks can be downloaded via scp, wget or curl
from Gerrit's daemon, and then executed on the client system.

To download a client command or hook, use scp or an http client:

----
$ scp -p -P 29418 john.doe@review.example.com:bin/gerrit-cherry-pick ~/bin/
$ scp -p -P 29418 john.doe@review.example.com:hooks/commit-msg .git/hooks/

$ curl -Lo ~/bin/gerrit-cherry-pick http://review.example.com/tools/bin/gerrit-cherry-pick
$ curl -Lo .git/hooks/commit-msg http://review.example.com/tools/hooks/commit-msg

[[client_commands]]
=== Commands

link:cmd-cherry-pick.html[gerrit-cherry-pick]::
	Download and cherry-pick one or more changes (commits).

[[client_hooks]]
=== Hooks

Client hooks can be installed into a local Git repository, improving
the developer experience when working with a Gerrit Code Review
server.

link:cmd-hook-commit-msg.html[commit-msg]::
	Automatically generate `Change-Id:` tags in commit messages.


== Server

Aside from the standard Git server side actions, Gerrit supports
several other commands over its internal SSH daemon.  As Gerrit does
not provide an interactive shell, the commands must be triggered
from an ssh client, for example:

----
  $ ssh -p 29418 review.example.com gerrit ls-projects
----

see link:user-upload.html#test_ssh[Testing Your SSH Connection].

[[trace]]
=== Trace

For executing SSH commands tracing can be enabled by setting the
`--trace` and `--trace-id <trace-id>` options. It is recommended to use
the ID of the issue that is being investigated as trace ID.

----
  $ ssh -p 29418 review.example.com gerrit create-project --trace --trace-id issue/123 foo/bar
----

It is also possible to omit the trace ID and get a unique trace ID
generated.

----
  $ ssh -p 29418 review.example.com gerrit create-project --trace foo/bar
----

Enabling tracing results in additional logs with debug information that
are written to the `error_log`. All logs that correspond to the traced
request are associated with the trace ID. The trace ID is printed to
the stderr command output:

----
  TRACE_ID: 1534174322774-7edf2a7b
----

Given the trace ID an administrator can find the corresponding logs and
investigate issues more easily.
