What's your shell? You might need the 'disown' command, otherwise, some shells'll try to do job control on the background process and wait for it to quit before it finishes. This doesn't happen without -t because no tty means no job control...

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.

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:

No - then it calls the function in... (4 Replies)

setsid
setsid(2) System Calls setsid(2)
NAME
setsid - create session and set process group ID
SYNOPSIS
#include <sys/types.h>
#include <unistd.h>
pid_t setsid(void);
DESCRIPTION
The setsid() function creates a new session, if the calling process is not a process group leader. Upon return the calling process will be
the session leader of this new session, will be the process group leader of a new process group, and will have no controlling terminal. The
process group ID of the calling process will be set equal to the process ID of the calling process. The calling process will be the only
process in the new process group and the only process in the new session.
RETURN VALUES
Upon successful completion, setsid() returns the value of the process group ID of the calling process. Otherwise it returns (pid_t)-1 and
sets errno to indicate the error.
ERRORS
The setsid() function will fail if:
EPERM The calling process is already a process group leader, or the process group ID of a process other than the calling process
matches the process ID of the calling process.
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
+-----------------------------+-----------------------------+
|Interface Stability |Standard |

|MT-Level |Async-Signal-Safe |
+-----------------------------+-----------------------------+
SEE ALSO
getsid(2), setpgid(2), setpgrp(2), attributes(5), standards(5)
WARNINGS
A call to setsid() by a process that is a process group leader will fail. A process can become a process group leader by being the last
member of a pipeline started by a job control shell. Thus, a process that expects to be part of a pipeline, and that calls setsid(), should
always first fork; the parent should exit and the child should call setsid(). This will ensure that the calling process will work reliably
when started by both job control shells and non-job control shells.
