Problem with nohup use in scripting

I am trying to execute following code:
Code:
alarm_file_array="test1.alarms test2.alarms test3.alarms test4.alarms"
for file in ${alarm_file_array[@]}
do
	nohup tail -f $file |awk 'NR>10' >> output.alarms 2>/dev/null &
done

Whenever it tries to execute nohup command it hangs because of the following prompt in output.
Code:
linus> Sending output to nohup.out

I tried to suppress nohup output using 2>/dev/null but still its not working.

Any ideas/suggestions are appreciated.

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. AUTHOR
