I have a script which is running a remote command on hundreds of boxes, it takes around 5 minutes to return an output from this command and because i am running this all from a central box, it goes off to each box in my for loop sequentially meaning that my script will wait for output before moving to the next machine
so as an example i will use the command `sleep 30`. I tried putting an ambersand into the script to no avail...the output on my central server still sits and waits for each box to sleep for 30 seconds rather than sending the command off to a box, letting that box deal with it and moving onto the next box with no delay
an example
Code:
for hostname in $list
do
/usr/ucb/echo -n "$hostname - "
ssh $hostname 'sleep 30 &'
done

push
PUSH(8) BSD System Manager's Manual PUSH(8)NAME
push -- fetch mail via POP
SYNOPSIS
push [-5 | --krb5] [-v | --verbose] [-f | --fork] [-l | --leave] [--from] [-c | --count] [--headers=headers] [-p port-spec |
--port=port-spec] po-box filename
DESCRIPTION
push retrieves mail from the post office box po-box, and stores the mail in mbox format in filename. The po-box can have any of the follow-
ing formats:
'hostname:username'
'po:hostname:username'
'username@hostname'
'po:username@hostname'
'hostname'
'po:username'
If no username is specified, push assumes that it's the same as on the local machine; hostname defaults to the value of the MAILHOST environ-
ment variable.
Supported options:
-5, --krb5
use Kerberos 5 (if compiled with support for Kerberos 5)
-f, --fork
fork before starting to delete messages
-l, --leave
don't delete fetched mail
--from behave like from.
-c, --count
first print how many messages and bytes there are.
--headers=headers
a list of comma-separated headers that should get printed.
-p port-spec, --port=port-spec
use this port instead of the default 'kpop' or '1109'.
The default is to first try Kerberos 5 authentication and then, if that fails, Kerberos 4.
ENVIRONMENT
MAILHOST
points to the post office, if no other hostname is specified.
EXAMPLES
$ push cornfield:roosta ~/.emacs-mail-crash-box
tries to fetch mail for the user roosta from the post office at ``cornfield'', and stores the mail in ~/.emacs-mail-crash-box (you are using
Gnus, aren't you?)
$ push --from -5 havregryn
tries to fetch From: lines for current user at post office ``havregryn'' using Kerberos 5.
SEE ALSO from(1), pfrom(1), movemail(8), popper(8)HISTORY
push was written while waiting for movemail to finish getting the mail.
