Nohup in conjunction with time

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.

I'd prefer bash solutions.

The output of from the time keyword or shell built-in should be directed to the standard error output. Try:
Code:
nohup time ls -1 >output.txt 2>&1
