I have a file with numbers separated by ,(comma). In between it also contains a number range like 300-400. Say for example I have a text file, namely testme.txt which looks like,
        200,300,234,340-350,400,360,333-339
        409-420
        4444-31231231
        348
 I want to find out whether number 348 is present or not. 348 is present in 2 places:
- 340-350
 - In last line.
 
 How to find it?. I tried using regex in sed,awk, but I am not able to completely write the script to capture the number range. Is there any other way to find it?
UPDATE: Found 1 brute force solution & itsit's working only for range.
        count=0;
        num1=348;
        for i in `sed 's/\([0-9]\+\-[0-9]\+\)/:&:/g' testme.txt  | 
    awk -F: '{ for(i=1; i<=NF; i++) if($i ~/[0-9]+-[0-9]+/){print $i} }'`;       
do 
    lh=`echo $i | awk -F\- '{print $1}'`; 
    rh=`echo $i | awk -F\- '{print $2}'`;  
    if [ $lh -le $num1 -a $rh -ge $num1 ]; 
    then  count=`expr 
 $count + 1`; fi; done
   count=`expr $count + 1`; 
    fi; 
done
echo $count;
