script to search for the contents of a file
Hi all,

Please see my requirement and post me asap.

Spool all the tables names into a file . Take each table name and check if it is present in any of the scripts in a directory using grep -il command. The script has to loop through the tables list and take each table and find it's presence in directory. After this exercise, we need to get the list of tables that not present in any of the scripts.

As I am beginner to this shell scripting, I have given the below logic for this to be done. Logic can be same , but I want a clean debugged script.
I am not able to use the variables properly. Please let me know how to use the variables in this case.

Script:

for i in all_tables.txt (this is the spooled file which contains the table names)

do

tbl= head -i all_tables.txt|tail -1

search=grep -il tbl *

if(test -z $search)

then echo ${tbl}>>unused (I wanted to created a file with all the tables which are not used in the scripts)

fi

done

Thanks
Vasundhara

       If no arguments are given, tbl reads the standard input, so it may be used as a filter.	When tbl is used with eqn or neqn the tbl  command
       should be first, to minimize the volume of data passed through pipes.
