Hi,

I have created one shell script in which it will count number of "~" tilda charactors from each line of the file.But the problem is that i need to count each line count individually, that means. if line one contains 14 "~"s and line two contains 15 "~"s then it should give an error msg.each line having same number of "~"s. so i need to check each line is having same "~" or not . my script gives me output like

**output**

Code:

total =        2
linelength=       62
14
linelength=       62
28

my script

Code:

#!/bin/bash
DATA_DIR=/export/opt/rtrupld/autosys/scripts_old
data=`ls $DATA_DIR/count.txt`

#     count1=1
var=`wc -l < $data`
#var2=`expr $var + 1`
echo "total = $var"
#var3=14

tildacount=0
while read line
do
   count=0
   linelen=`echo "$line"|wc -c`
 
echo "linelength= $linelen"
   if [ $linelen -gt 0 ]
     then 

# echo $linelen
       until [ $count -ge $linelen ]
     do
         count=`expr  $count + 1 `
         char=`echo "$line"|cut -b"$count"`
         if [ "$char" = "~" ]
         then
            tildacount=`expr  $tildacount + 1`
 
     fi
 
     done
     echo $tildacount

  fi
done < $data
#echo $tildacount
