I have a fairly simple script like so:
This works great when using ssh server "script.sh" but not when using ssh -t server "script.sh"
The solution I came up with was to call sleep after recording the child pid. My guess at the problem is that the script and pseudo-tty are destroyed before the child process actually starts. Is there a better way to wait until the child starts before returning? Should I use something other than nohup to ensure the child starts?
I have to use ssh -t because of other constraints.

Hi,
Using nohup it sends output automatically to $HOME/nohup.out - how do I direct this output to another named file instead, so I can run several scripts in the background at once, directing their outputs into individual log files?

I find that if I use nohup (in bourne shell script) then all the interactive parts in my code are gone hidden... e.g., the places asking input from the user (such as ckyorn) will not be displayed. This is no good.
Is there a way to use nohup (or similar utility) and meanwhile, to keep the... (9 Replies)
I'm trying to ssh into a remote server, run a script which may or may not start a nohup'd background process and then exit leaving the process running on the remote server. I'm looping through a number of servers to do this but the script hangs as soon as it comes to a server where the remote... (3 Replies)
Hi,
I've read the man page on nohup.
But I still can't see what's the differences if
we just send a process to background versus
sending a nohup process to background.
eg:
myprocess &
vs
nohup myprocess &
Without nohup, myprocess would still run uninterruptible
at background... (2 Replies)

Hello,
I am trying to find a way to send several sequential commands via SSH to a remote box in a single command.
Thoughts so far:
1) Can I put them into a function and call the function within the ssh command?
e.g.
ssh <targetserver> $(functionx)
No - then it calls the function in... (4 Replies)

nohup
NOHUP(1) BSD General Commands Manual NOHUP(1)NAME
nohup -- invoke a utility immune to hangups
SYNOPSIS
nohup [--] utility [arguments]
DESCRIPTION
The nohup utility invokes utility with its arguments and at this time sets the signal SIGHUP to be ignored. If the standard output is a ter-
minal, the standard output is appended to the file nohup.out in the current directory. If standard error is a terminal, it is directed to
the same place as the standard output.
Some shells may provide a builtin nohup command which is similar or identical to this utility. Consult the builtin(1) manual page.
ENVIRONMENT
The following variables are utilized by nohup:
HOME If the output file nohup.out cannot be created in the current directory, the nohup utility uses the directory named by HOME to create
the file.
PATH Used to locate the requested utility if the name contains no '/' characters.
DIAGNOSTICS
The nohup utility exits with one of the following values:
126 The utility was found, but could not be invoked.
127 The utility could not be found or an error occurred in nohup.
Otherwise, the exit status of nohup will be that of utility.
SEE ALSO builtin(1), csh(1), signal(3)STANDARDS
The nohup utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
BUGS
Two or more instances of nohup can append to the same file, which makes for a confusing output.
