Hi,
How do I store following command output:
export RESULT=`date` &
It works when I do :
export RESULT=`date`
But what I need is when command put it background, I also need that output going to RESULT variable.
Is there any way ?
Thanks

Not sure why this does not work in bash:
tail -f err.log |&
-bash: syntax error near unexpected token `&'
I am attempting to continuously read a file that is being updated by doing a "tail -f" on the file and piping the output to stdin which can then be read by the next shell command

I want to send that foreground process to the background, but also have it direct the output to a logfile.

Hello,
I unfortunately have a process that does two things, it returns an answer to me and then does a bunch of work that I would like to wait on. Here is a simple example:
#!/bin/bash
function p_w {
echo "poopy"
sleep 10
echo "scoop"
}
foo=$(p_w &)
sleep 1

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 have a background process that's been running way longer than usual. It doesn't output anything to a file, so I can't 'tail -f' it. Is there a command that will enable me to... (2 Replies)
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)
Is there any way to trigger a sequence of commands in parallel and capture their output in variables? e.g. something on the following lines
x=`echo "X" &`
y=`echo "Y" &`
z=`echo "Z" &`
so that $x, $y, and $z evaluate to X, Y and Z res. (7 Replies)
I have a question.
I will be running a background process using nohup and & command at end. I want to send output to a file say myprocess.out.
So will this command work?
nohup myprocess.ksh > myprocess.out &
Thanks in advance guys !!!

DESCRIPTION

If standard input is a terminal, redirect it from /dev/null. If standard output is a terminal, append output to `nohup.out' if possible,
`$HOME/nohup.out' otherwise. If standard error is a terminal, redirect it to standard output. To save output to FILE, use `nohup COMMAND
> FILE'.
NOTE: your shell may have its own version of nohup, which usually supersedes the version described here. Please refer to your shell's doc-
umentation for details about the options it supports.
