I have the below script, it is ok to run on local server

#cat /etc/passwd | awk -F: '{ print $1}'

root
bin
daemon
adm
lp
sync
shutdown
halt


But if I try to run it at remote server , i tried ssh root@192.6.4.108 "cat /etc/passwd | awk -F: '{ print $1}'" , then the output is as below , the output format is different , can advise what is wrong , how can i use the existing script to run on remote server ? thx




root:x:0:0:root:/root:/bin/bash
bin:x:1:1:bin:/bin:/sbin/nologin
daemon:x:2:2:daemon:/sbin:/sbin/nologin
adm:x:3:4:adm:/var/adm:/sbin/nologin
lp:x:4:7:lp:/var/spool/lpd:/sbin/nologin
sync:x:5:0:sync:/sbin:/bin/sync
shutdown:x:6:0:shutdown:/sbin:/sbin/shutdown
halt:x:7:0:halt:/sbin:/sbin/halt

$1 is treated as a shell variable. you need to "escape" the $:

ssh root@192.168.4.108 "awk -F: '{print \$1}' /etc/passwd"

(oh i omitted your cat - its pretty much useless. )
