I am trying to execute a script which grep the mount from fstab. when script is executed it gives multiple mounts matching the words instead of exact word matching.

#!/bin/bash
FNAME=$1
NFSSERVER=$2
NFSSHARE=$3
FILEPATH=/home/kumar/files

[ $# -ne 3 ] && echo "Usage: ./$0 FILENAME NFSSHARE NFSSERVER "; exit 1; 

for I in `cat $FILEPATH/$FNAME|tr ":" "n"`
do
 echo | tee -a $FILEPATH/$NFSSERVER-$NFSSHARE-fstab.txt
 echo -e "$I ~ c" | tee -a $FILEPATH/$NFSSERVER-$NFSSHARE-fstab.txt
 sshpass -f $FILEPATH/.pass ssh -q $I "grep -w $NFSSHARE /etc/fstab | grep -i $NFSSERVER" | tee -a $FILEPATH/$NFSSERVER-$NFSSHARE-fstab.txt
done

If I search for "apps_stage" NFSSHARE then the output comes for apps_stage, apps_stage_new, apps_stage_log. But the expected output is only for apps_stage.

The above script gives below output

nfs-1:/apps_stage /apps nfs _netdev,nolock,rsize=1048600,wsize=1048600 0 0
nfs-1:/apps_stage_new /apps/new nfs _netdev,nolock,rsize=1048600,wsize=1048600 0 0
nfs-1:/apps_stage_log /apps/log nfs _netdev,nolock,rsize=1048600,wsize=1048600 0 0

Expected output is only one line below

nfs-1:/apps_stage /apps nfs _netdev,nolock,rsize=1048600,wsize=1048600 0 0

When I run the same as a command in shell it works perfectly right.

NFSSHARE=apps_stage
NFSSERVER=nfs-1
I=testserver-1

sshpass -f ./files/.pass ssh -q $I "grep -w $NFSSHARE /etc/fstab | grep -i $NFSSERVER"

The above command gives me the exact required output as below.

nfs-1:/apps_stage /apps nfs _netdev,nolock,rsize=1048600,wsize=1048600 0 0

Not sure why it's not working in a script and working in the shell. Request you to guide me to make it work in a script.
