need help in string patterns
Hi,

i have following lines of code which is properly working.
Code:
 
CAT1="${InputFile}CAT_*0[0|1|2|3]?????"
CAT2="${InputFile}CAT_*0[4|5|6|7]?????"
 
CountRecords(){
integer i=1
while [[ $# -ne 0 ]]; do
print P$i `nawk 'END {print NR}' $1 ` >> ${OutputPath}result.txt &
i=i+1
shift
done
}
CountRecords "$CAT1" "$CAT2"

here CountRecords function accept "$CAT1" as 1st argument and "$CAT2" as second argument
what i want is to store "$CAT1" "$CAT2" in a variable and then apply to the function like

Code:
 
CAT="$CAT1 $CAT2"
CountRecords $CAT

When i tried this CountRecords accept both CAT1 and CAT2 as a single argument. i require the correct pattern so that it may take it again as two arguments

Plz help me
