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

ACPIDUMP(1) General Commands Manual ACPIDUMP(1)
NAME
acpidump - ACPI table dump utility
SYNOPSIS
acpidump [<option>...]
DESCRIPTION
This manual page briefly documents the acpidump command. The option list is taken from the interactive help.
The acpidump command extracts the ACPI tables currently in use from the running kernel in a form usable for later processing by the acpix-
tract command.
Invocation of acpidump without parameters will dump all available ACPI tables. Multiple mixed instances of the -a , -f , and -n parameters
can be used.
OPTIONS
-b Dump tables in binary format (versus the default human-readable form)
-h | -?
Display this help message
-o <file>
Redirect output to a file. This file can be used later by acpixtract to examine the contents of the ACPI tables.
-s Print table summaries only.
-v Print the version of this utility.
-z Verbose mode.
-a <address>
Get a table from a physical address (must be superuser and you must be careful which address you use -- dmesg will typically report
the addresses for the various tables).
-f <binary-file>
Get a table from a binary file (see the -b option).
-n <signature>
Get a table via it's name or signature (e.g., MADT or SSDT).
