awk different outputs each time

SureshM · 04-11-2013, 08:28 AM

I have a strange issue.

Code:

(awk '$3 == "nfs" { cnt++ }; END { print cnt }' /etc/fstab)

This is giving different count each time.

To test this, tried the one here

Code:

-bash-3.2$ awk '/nfs/{print $2}' /etc/fstab | wc -l
151
-bash-3.2$ awk '/nfs/{print $2}' /etc/fstab | wc -l
145
-bash-3.2$ awk '/nfs/{print $2}' /etc/fstab | wc -l
150

checking the output, it has all wired outputs each time, since command was searching for "nfs", it is giving all non matched strings. output were always different.

do
/boot
/tmp
/var
none
/dev/pts

The same script is working on all other 100+ machines, only one machine is showing the wired stuff.
any ideas/thoughts ?

What is the output of the following command (on the box that has this issue):

Code:

file /etc/fstab

druuna :

ASCII text

its not an issue with file type, its happening with every file

Code:

552
-bash-3.2$ awk '/bash/{print $1}' /etc/passwd | wc -l
556
-bash-3.2$ awk '/bash/{print $1}' /etc/passwd | wc -l
552

-bash-3.2$ awk '/nfs/{print $1}' /proc/mounts | wc -l
147
-bash-3.2$ awk '/nfs/{print $1}' /proc/mounts | wc -l
145
