Hi,
Are there any options for using options like RPAD(),LPAD() functions in SQL?If yes, How can I use grep command with thease options?

Any help would be appreciated.
Thanks in Advance.

Hi harish,

I don't know about those function (SQL). can you give more details.

Thanks

Hi Srikanth,
Consider below:-
test___1
test___2
test__10
test_110

Thease are the contents of a file where the number column is right aligned.
Please consider "___" symbol as blank spaces.
If I want to extract "test 110", I give grep "test $no" where no is a variable and consider now it is 110. This will extract "test 110". If I want to extract "test 10", If I give the same command grep "test $no", where no is 10, It won't extract because of it has got 2 blank spaces between test and 10. So I need to have a option like LPAD in other languages, E.g. LPAD("10",3," ") will return 1 blank space followed by 10. So I can assign this value to a variable and now the value can be no=" 10". Now I can go with grep, It will work.

I hope you understood this.
Any suggestion on this?
TIA

I think , It would be helpful for you

FILE=input_filename
no=10
        cat $FILE | awk '$2 ~ /'"$no"'/ {print $1 " " $2}'

try this

no=1
grep "test *$no$" file

no=1
sed -n "/test *$no$/p" file

Another way using grep :

grep "test[[:space:]]*$no" file
