.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.
