So while running the script I need to type SCRIPT.sh -xv.

You meant to say that?

You can simply modify the shebang in your script:
Code:
#!/bin/ksh -xv
i=1
while [ $i -le 5 ]
do
        j=0
        while [ $j -lt $i ]
        do
                echo "$i"
                j=`expr $j + 1`
        done
        i=`expr $i + 1`
done

Use the -n option of the print-builtin

Code:
print -n $j

The echo command is not portable in this respect. Some systems use echo -n text others echo text\c.

Code:
#!/bin/ksh
i=1
while [ $i -le 5 ]
do
j=0
out=""
 while [ $j -lt $i ]
 do
  out=$out$i
  j=`expr $j + 1`
 done
echo "$out"
i=`expr $i + 1`
done

Code:
i=`expr $i + 1`

This can be change to
((i=i+1)) or ((i++))

print -n option gives me below output:

122333444455555

However, I need output

22
333
4444
55555
