| .SH DETAILS |
| .PP |
| Executes the same shell command in each project. |
| .PP |
| The \fB\-r\fR option allows running the command only on projects matching regex or |
| wildcard expression. |
| .PP |
| By default, projects are processed non\-interactively in parallel. If you want to |
| run interactive commands, make sure to pass \fB\-\-interactive\fR to force \fB\-\-jobs\fR 1. |
| While the processing order of projects is not guaranteed, the order of project |
| output is stable. |
| .PP |
| Output Formatting |
| .PP |
| The \fB\-p\fR option causes 'repo forall' to bind pipes to the command's stdin, stdout |
| and stderr streams, and pipe all output into a continuous stream that is |
| displayed in a single pager session. Project headings are inserted before the |
| output of each command is displayed. If the command produces no output in a |
| project, no heading is displayed. |
| .PP |
| The formatting convention used by \fB\-p\fR is very suitable for some types of |
| searching, e.g. `repo forall \fB\-p\fR \fB\-c\fR git log \fB\-SFoo\fR` will print all commits that |
| add or remove references to Foo. |
| .PP |
| The \fB\-v\fR option causes 'repo forall' to display stderr messages if a command |
| produces output only on stderr. Normally the \fB\-p\fR option causes command output to |
| be suppressed until the command produces at least one byte of output on stdout. |
| .PP |
| Environment |
| .PP |
| pwd is the project's working directory. If the current client is a mirror |
| client, then pwd is the Git repository. |
| .PP |
| REPO_PROJECT is set to the unique name of the project. |
| .PP |
| REPO_PATH is the path relative the the root of the client. |
| .PP |
| REPO_REMOTE is the name of the remote system from the manifest. |
| .PP |
| REPO_LREV is the name of the revision from the manifest, translated to a local |
| tracking branch. If you need to pass the manifest revision to a locally executed |
| git command, use REPO_LREV. |
| .PP |
| REPO_RREV is the name of the revision from the manifest, exactly as written in |
| the manifest. |
| .PP |
| REPO_COUNT is the total number of projects being iterated. |
| .PP |
| REPO_I is the current (1\-based) iteration count. Can be used in conjunction with |
| REPO_COUNT to add a simple progress indicator to your command. |
| .PP |
| REPO__* are any extra environment variables, specified by the "annotation" |
| element under any project element. This can be useful for differentiating trees |
| based on user\-specific criteria, or simply annotating tree details. |
| .PP |
| shell positional arguments ($1, $2, .., $#) are set to any arguments following |
| <command>. |
| .PP |
| Example: to list projects: |
| .IP |
| repo forall \fB\-c\fR 'echo $REPO_PROJECT' |
| .PP |
| Notice that $REPO_PROJECT is quoted to ensure it is expanded in the context of |
| running <command> instead of in the calling shell. |
| .PP |
| Unless \fB\-p\fR is used, stdin, stdout, stderr are inherited from the terminal and are |
| not redirected. |
| .PP |
| If \fB\-e\fR is used, when a command exits unsuccessfully, 'repo forall' will abort |
| without iterating through the remaining projects. |
