I let a script A call script B.
I used
nohup a.sh &>/tmp/log &
In script A it calls B directly, without any redirecting or nohup or background.
However A is always "Stopped", while B is running correctly. Anybody knows why?
thanks!

I'm pretty sure I had the answer to this months ago and have misplaced it. Needless to say I will bookmark it this time.

I played a bit around with the Terminal and I observed something.
When I start and kill a background process, there is some kind of output. After I invoked the command to start the process the first message " 13063" is directly displayed. However, after killing the process, the second message "+... (3 Replies)

Hello,
I am trying to make a bash script, I tested nohup but it did not help me.
My code is:

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.
