I have the following script written for this,as i told i am novice in this shell scripting field so i need some guidance,There are erros when i ran the script but its hard for me to track them.

Code:
       echo "enter the file name"
       read file
       k=1
       n=1,o=10,p=19
       for firstline in $file
       do
       firstline = `sed -n $k p $file`
       num1 = `cut -f$n -d "," -s $firstline` 
       num2 = `cut -f$o -d "," -s $firstline`
       num3 = `cut -f$p -d "," -s $firstline`

        
      if [ $num1 -lt $num2 && $num1 -lt $num3 && $num2 -lt $num3 ]
       then
       echo " Numbers in column are in ascending order"
        else
          echo " Numbers not in ascending order in columns"
          n = `expr $n + 1`
          o = `expr $o + 1`
          p = `expr $p + 1`
      fi

        echo " To check the total numbers in a row "
        for a in firstline
         do
          a = `cut -f1-9 -d  "," -s $firstline`
          count=0
          digits = `grep [0-9][1-9] a`
           count = `expr $count + 1`
           echo " The total number of digits in a row is $count "
           done
     k = `expr $k + 1`
 
     echo "To check total numbers in an entry"

       for tdigits in firstlineline
        do
         count=0
         tdigits = `grep [0-9][1-9] firstline`
         echo "The total Numbers of digits are $count"
         count = `expr $count + 1`
         done
        echo " We have completed the task,at the end of program"
 done

echo(1B)					     SunOS/BSD Compatibility Package Commands						  echo(1B)

NAME
echo - echo arguments to standard output SYNOPSIS
/usr/ucb/echo [-n] [argument] DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output. echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi- ronment variables. For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows: o echo your current-working-directory's full pathname o pipe the output through tr to translate the path's embedded slash-characters into space-characters o pipe that output through wc -w for a count of the names in your path. example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w" See tr(1) and wc(1) for their functionality. The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's echo() also understands a as the audible bell character; however, these commands do not have an -n option. OPTIONS
-n Do not add the NEWLINE to the output. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWscpu | +-----------------------------+-----------------------------+ SEE ALSO
csh(1), echo(1), ksh(1), sh(1), tr(1), wc(1), attributes(5) NOTES
The -n option is a transition aid for BSD applications, and may not be supported in future releases. SunOS 5.10 3 Aug 1994 echo(1B)
