Usage: install [-s KERNEL] [-m ARCH] [-d DIR] [-p CMD] [-e ERRFD] [-f|-n] [-- CMD [ARG]...]
|
|
|
|
If positional arguments are specified, call this on success:
|
|
|
|
CMD [ARG]... DAEMON VERSION INSTALLED
|
|
|
|
DAEMON is path to gitstatusd. VERSION is a glob pattern for the
|
|
version this daemon should support; it's supposed to be passed as
|
|
-G to gitstatusd. INSTALLED is 1 if gitstatusd has just been
|
|
downloaded and 0 otherwise.
|
|
|
|
Options:
|
|
|
|
-s KERNEL use this instead of lowercase `uname -s`
|
|
-m ARCH use this instead of lowercase `uname -m`
|
|
-d DIR use this instead of `dirname "$0"`
|
|
-p CMD eval this every second while downloading gitstatusd
|
|
-e ERRFD write error messages to this file descriptor
|
|
-f download gitstatusd even if there is one locally
|
|
-n do not download gitstatusd (fail instead)
