Issue resolved...i missed out a single quote , so for that reason it was showing END OF FILE Error.

Problem while acurate pattern matching.....
All,

I have a script which looks as follows,


fileConfigTable_length=( "XX"
"FILE_TYPE"
"CS_ID"
"FILE_DESC"
"FILE_SCHDL_TYPE"
"FILE_SCHDL"
"FILE_SCHDL_TIME"
"RESULT"
"UNIT_TYPE"
"UNIT_NAME")
function fetch_Records
{
var=$1
eval $(awk -F \| -v find=$var '{
for(f=1;f<=NF;f++)
if(match($f,find))
printf "%s[%d]=\"%s\"\n", substr($f,1,RLENGTH), ++c, substr($f,RLENGTH+2)
}' noname.txt )
}

total_Array=${#fileConfigTable_length[*]}
i=1
while [ $i -lt $total_Array ]
do
fetch_Records ${fileConfigTable_length[$i]}
i=`expr $i + 1`
done


and noname.txt is

FILE_TYPE=01|FILE_DESC=Periodic|FILE_SCHDL_TYPE=Daily|FILE_SCHDL=|FILE_SCHDL_TIME=9:00am|RESULTS=B|U NIT_TYPE=PEP|UNIT_NAME=BUNL001PEP
FILE_TYPE=02|FILE_DESC=NCTO|FILE_SCHDL_TYPE=Daily|FILE_SCHDL=|FILE_SCHDL_TIME=9:00am|RESULTS=M|UNIT_ TYPE=SAN|UNIT_NAME=BUNL001SAN


The problem starts when the search pattern is FILE_SCHDL,
as it is showing the values as follows

FILE_SCHDL[1]="TYPE=Daily" FILE_SCHDL[2]="" FILE_SCHDL[3]="TIME=9:00am" FILE_SCHDL[4]="TYPE=Daily" FILE_SCHDL[5]="" FILE_SCHDL[6]="TIME=9:00am"


[ these are combination of values for FILE_SCHDL_TYPE,FILE_SCHDL_TIME and FILE_SCHDL ]

can any body suggest how to make the exact match in my above script ..
so that it will give me exact match ???

FILE_TYPE=02|FILE_DESC=NCTO|FILE_SCHDL_TYPE=Daily|FILE_SCHDL=|FILE_SCHDL_TIME=9:00am|RESULTS=M

$ eval $(awk -F \| -v find=FILE_DESC '{

>     if(match($f,find))
>       printf "%s[%d]=\"%s\"\n", substr($f,1,RLENGTH), ++c, substr($f,RLENGTH+2)
>  }' file1)

$ echo ${FILE_DESC[1]}
Periodic

$ echo ${FILE_DESC[2]}
NCTO

The scripts works fine for everything other than search pattern FILE_SCHDL

FILE_SCHDL[1]="TYPE=Daily" FILE_SCHDL[2]="" FILE_SCHDL[3]="TIME=9:00am" FILE_SCHDL[4]="TYPE=Daily" FILE_SCHDL[5]="" FILE_SCHDL[6]="TIME=9:00am"

if i put my serach pattern as FILE_SCHDL, it gives all the combination of
values FILE_SCHDL_TYPE,FILE_SCHDL and FILE_SCHDL_TIME from i/p file.

can you help me out modifying the query for exact match with array ????

To be honest, I can't see the point in posting a question twice, sending a private message, and 'bumping-up' your post after an hour. I'm not even in the same time-zone.

So anyway, you need to match the variable name and the following equals sign. Changes highlighted...
Code:
eval $(awk -F \| -v find=$var '{
     for(f=1;f<=NF;f++)
       if(match($f,find "="))
         printf "%s[%d]=\"%s\"\n", substr($f,1,RLENGTH-1), ++c, substr($f,RLENGTH+1)
   }' noname.txt)
