hi don,

is there any possibility in shell script to write $1,$2, exit status in the log file.

Code:
NOW=$(date +"%F")
NOWT=$(date +"%T")
## Backup path ##
BAK="/systems/logfile/$NOW.$NOWT.txt"
touch $BAK
var=$1
inp=$2
if [ ! -d ${comp_dir} ]; then
exit=1 
exit 1
else
exit=0
exit 0
fi

You can't write to a log file after you exit.

Code:
 need to print only the exit status and input given by the user.

Why do you care if the exit status is stored in a variable before you write it?
Code:
 Just to check whether it is correct

What is the name of the log file?
Code:
NOW=$(date +"%F")
NOWT=$(date +"%T")
## Backup path ##
BAK="/systems/logfile/$NOW.$NOWT.txt"

Do you want to append data to the end of the log file, or do you want to replace the entire contents of your log file each time you run your script?
Code:
 need to create a new file everytime

Do you really just want to write a 0 or 1 to your log file? Or, do you want the name of the program producing that line to be included in the log file?
Code:
  i need the exit status need to be redirected to the output and also along with the input

If you just want a 0 or 1 in a file, why not just capture the exit status of your program after it completes instead of creating a file?

yes

Do you want a timestamp showing when that entry was written to your log file? If you do, what format do you want to use? And, do you want to use local time or coordinated universal time (AKA GMT)?
yes local time

Log(4)							     Kernel Interfaces Manual							    Log(4)

NAME

       Log, .Log - Contains the uucp program log files

SYNOPSIS

       /usr/spool/uucp/.Log

DESCRIPTION

       The /usr/spool/uucp/.Log directories contain uucp program log files.  The uucp program normally places status information about each trans-
       action in the appropriate log file each time you use the networking utilities facility.	All transactions of the uucico and  uuxqt  daemons
       are  logged  in	files named for the remote system concerned.  The files are stored in a subdirectory of the /usr/spool/uucp/.Log directory
       named for the daemon involved.  Thus, the log files are named with a form of the following: /usr/spool/uucp/.Log/DaemonName/SystemName

       The uucp and uuto commands call the uucico daemon.  The uucico daemon activities for a particular remote system are logged in  the  System-
       Name file in the /usr/spool/uucp/.Log/uucico directory on the local system.

       The uux and uusend commands call the uuxqt daemon.  The uuxqt daemon activities for a particular remote system are logged in the SystemName
       file in the /usr/spool/uucp/.Log/uuxqt directory on the local system.

       When more than one uucp process is running, however, the system cannot access the standard log file, so it places the status information in
       a file with a .Log prefix that covers just the single transaction.

       The  uucp  program can automatically append the temporary log files to a primary log file.  This is called compacting the log files, and is
       handled by the uudemon.cleanu command, a shell procedure, which combines the log files of the activities of the uucico and uuxqt daemons on
       a system and stores them in the /usr/spool/uucp/.Old directory.

       The  default  is for the uudemon.cleanu command to save log files that are 2 days old.  This default can be changed by modifying the appro-
       priate line in the shell script.  If storage space is a problem on a particular system, reduce the number of days that the files  are  kept
       in the individual log files.

       The uulog command can be used to view the uucp program log files.

RELATED INFORMATION

       Daemons: cron, uucico(8), uusched(8)

       Commands: uucp(1), uudemon.cleanu(4), uulog(1), uusend(1), uuto(1), uux(1) delim off
