hi,
if I exectute "nohup time ls -1" I get the following output
Code:
[user@hostname directory]$ nohup time ls -1
file_1
file_2
file_3
file_4
file_5
0.000u 0.001s 0:00.00 0.0% 0+0k 0+0io 0pf+0w
This is all OK.
But if I want to capture this whole output in to a text file I would want to use something like
Code:
[user@hostname directory]$ nohup time ls -1 >output.txt
0.000u 0.002s 0:00.00 0.0% 0+0k 0+8io 0pf+0w
[user@hostname directory]$ more output.txt
file_1
file_2
file_3
file_4
file_5
output.txt
My problem is that the output.txt doesn't contain the result from the "time" command. It looks like to me that nohup didn't recognise that at the end of the command line, the output redirection was meant for the entire nohup command. ls -1 command seems to just take the output redirection for itself.
How can I get the entire result of nohup to be put in the output.txt file?
I tried a lot of weird ways but just couldn't get it worked.

Thanks in advance. (3 Replies)

nohup
NOHUP(1) User Commands NOHUP(1)NAME
nohup - run a command immune to hangups, with output to a non-tty
SYNOPSIS
nohup COMMAND [ARG]...
nohup OPTION
DESCRIPTION
Run COMMAND, ignoring hangup signals.
--help display this help and exit
--version
output version information and exit
If standard input is a terminal, redirect it from an unreadable file. 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.
