I have the file as below

server1 no dr aix 5300-05-03 9119-595 20-18888 yes ftp-eagle
server2 no dr aix 5300-05-03 9119-595 20-18888 yes ftp-eagle
server3 yes dr aix 5300-05-03 9119-595 20-18888 yes ftp-eagle
server4 yes dr aix 5300-05-03 9119-595 20-18888 yes ftp-eagle


When I run below from the shell :-
#FileName=/list.config
#cat $FileName | grep -v "#" | sed -e 's/ / /g' | awk '{print $1,$2}'| grep -w yes| cut -d' ' -f1
server3
server4

Now when I run from the shell script in this way:-
#!/bin/ksh
FileName=/list.config
awkfilter="$1,$2"
filter_string="yes"
temp_str=(cat $FileName | grep -v "#" | sed -e 's/ / /g' | awk '{print '$awk_filter'}' | grep -w "$temp_str1$Filter_String" |cut -d' ' -f1)
echo $temp_str
#######

is not giving the same above output that gave me from the shell.

The set -x for the cat in the script is :-
+ + cat /list.config
+ grep -v #
+ sed -e s/ / /g
+ awk {print $1,$2}
+ cut -d -f1
+ grep -w yes
temp_str=
+ echo



Can somebody please help me out to find why its not working inside the script?

NOw that the above problem is solved , I am stuck up with another grep issue,

I replaced the cat like below:-
cat $FileName | grep -v "#" | sed -e 's/ / /g' | awk '{print '$awk_filter'}' | grep -w $Filter_String

this works only if Filter_string has one word , if it has two words like "yes dr" then it gives
grep: 0652-033 Cannot open dr".

Here the grep is not taking the entire content of the $Filter_String to search ,rather it tries to search to search yes in the file dr. How we avoid this.
