I have create dthe unix script to check the file whether valid or not.

I have created the script. but it should be generic because no.of files and comparison value will be differenct(Eg:header identification number would 0 for some files and 1 for some file) for each process.

Can any body give some suggesions how we can do this. you can find the below script to check Quote:
Code:
#!/bin/bash 
set -x 
 
Result=0 
 
[ -f "$0.log" ] && > $0.log 
 
function log 
{ 
echo "$@" >> "$0.log" 
} 
 
for file in $1 $2 
 
do 
 
cd /informationserver/projects/project_Name/input/ 
if [ -f "$file" ] 
then 
if [ `grep "^[0]" $file | wc -l` = 1 ] 
then 
if [ `grep "^[9]" $file | wc -l` = 1 ] 
then 
Result=` expr $Result + 0` 
else 
Result= ` expr $Result + 1` 
log There is No Trailer in $file 
fi 
else 
if [ `grep "^[9]" $file | wc -l` = 1 ] 
then 
Result=` expr $Result + 1` 
log There is No Header in $file 
else 
Result=` expr $Result + 1` 
log There is No Header&Trailer in $file 
fi 
fi 
else 
log No $file exists in the directory. 
Result=` expr $Result + 1` 
fi 
 
done 
 
echo $Result

INTERFACE-ORDER(5)						    resolvconf							INTERFACE-ORDER(5)

NAME
interface-order - resolvconf configuration file DESCRIPTION
The file /etc/resolvconf/interface-order is used to control the order in which resolvconf nameserver information records are processed by those resolvconf update scripts that consult this file. (The name of the file is apt because a resolvconf nameserver information record is named after the interface with which it is associated.) The file contains a sequence of shell glob patterns, one per line. The position of a record in the order is the point at which its name first matches a pattern. Patterns may not contain whitespace, slashes or initial dots or tildes. Blank lines and lines beginning with a '#' are ignored. Resolvconf update scripts in /etc/resolvconf/update.d/ that consult this file include the current default versions of dnsmasq, pdnsd and libc. (Actually they don't read the file directly; they call the utility program /lib/resolvconf/list-records which lists records in the specified order and omits the names of empty records.) EXAMPLE
# /etc/resolvconf/interface-order # Use nameservers on the loopback interface first. lo* # Next use records for Ethernet interfaces eth* # Next use records for Wi-Fi interfaces wlan* # Next use records for PPP interfaces ppp* # Last use other interfaces * AUTHOR
