.TH QARSH 1 "8 July 2008"
.SH NAME
qarsh \- Quality Assurance Remote SHell
.SH SYNOPSIS
\fBqarsh\fR [-\fBl \fIuser\fR] [-\fBg \fIgroup\fR] [-\fBp \fIport\fR] [-\fBt \fItimeout\fR] [\fIuser\fR[.\fIgroup\fR]@]\fIhost command\fR
.SH DESCRIPTION
.B Qarsh
is used to execute commands on remote hosts as the specified user in a
test environment. It is intended as a replacement for ssh(1) in trusted
test environments where remote execution as arbitrary users is needed,
but security features like authentication or encryption are not.
.B Qarsh
transparently passes standard input, standard output, and standard
error. The signals SIGHUP, SIGINT, SIGTERM, SIGUSR1, and SIGUSR2 are
propagated to the remote command. The return status of the remote
command is recreated by \fBqarsh\fR, including death by signal.
.B Qarsh
talks to btimed(8) to determine if the host is up, down, or has
rebooted. This allows \fBqarsh\fR to exit with an error when a remote
host is not responsive or reboots during the execution of a command.
.B Qarsh
does not support interactive logins.
.SH OPTIONS
.TP
.BI \-g " group"
sets the remote group to \fIgroup\fR. Otherwise the default group of
the remote user will be used.
.TP
.BI \-l " user"
sets the remote user to \fIuser\fR. Otherwise the current local user
will be used.
.TP
.BI \-p " port"
connect to port \fIport\fR instead of the default port of 5008.
.TP
.BI \-t " timeout"
sets the number of seconds to wait when the remote host is not
responding to declare the host dead and exit.
.SH NOTES
When running remote commands in the background, be sure to close standard
output and standard error or redirect them to a file on the remote host.
Qarsh will wait for those file descriptors to close before returning which
will look like qarsh is not putting the command in the background.
