linux 命令的输出没有从控制台被抑制

Question

I am using the below command to remove write access for "other" users:

    df --local -P | awk {'if (NR!=1) print $6'} | xargs -I '{}' find '{}' -xdev -type f -perm -0002 | awk -F"/" {'if ($5!="tmp") print $0'} | xargs chmod o-w

I need all error and output messages to be suppressed from console. I'm however getting this messages still:

find: /data0101/track_logs/IMEI_TRACK_9_20141127_01010014.LOG: No such file or directory
find: /data0101/track_logs/IMEI_TRACK_4_20141123_01010014.LOG: No such file or directory
find: /data0101/track_logs/IMEI_TRACK_7_20141122_01010014.LOG: No such file or directory

I tried all combinations like this at the end of my command:

&> /dev/null
>/dev/null 2>&1
2&>1 >/dev/null

But it doesn't help. My shell is :

# echo $SHELL
/bin/bash

Kindly help

You are close to your answer. Since the error is coming from the find command, you need to redirect the error of xargs -I '{}' find '{}' -xdev -type f -perm -0002 command.

So it would be:

xargs -I '{}' find '{}' -xdev -type f -perm -0002 2>/dev/null

Also, as stated by @HuStmpHrrr to redirect the error messages for your entire long command, use {long_command;} 2>/dev/null
