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

tbl(1) User Commands tbl(1)
NAME
tbl - format tables for nroff or troff
SYNOPSIS
tbl [-me] [-mm] [-ms] [filename]...
DESCRIPTION
tbl is a preprocessor for formatting tables for nroff(1) or troff(1). The input filenames are copied to the standard output, except that
lines between .TS and .TE command lines are assumed to describe tables and are reformatted.
If no arguments are given, tbl reads the standard input, so tbl may be used as a filter. When tbl is used with eqn(1) or neqn, the tbl
command should be first, to minimize the volume of data passed through pipes.
OPTIONS
-me Copy the -me macro package to the front of the output file.
-mm Copy the -mm macro package to the front of the output file.
-ms Copy the -ms macro package to the front of the output file.
EXAMPLES
Example 1: Using tbl
As an example, letting `@' (at-sign) represent a TAB, which should be typed as an actual TAB character in the input file
.TS
c s s
c c s
