This is in Unix Shell Scripting. using Putty.exe The application I'm working on is to add,remove and update the information of a person.I need help to create a file config.bat so it will automatically create the person's ID number. I would like to start from 1000 then add 1 everytime I add a person. This is the code I have to add the person. I'm missing the ID number. answer=y while [ "$answer" = y ] do clear echo -e "First Name: \b\c " read first clear echo -e "Last Name: \b\c" read last clear echo -e "M: \b\c " read m clear echo -e "Street: \b\c" read street clear echo -e "City: \b\c" read city clear echo -e "State: \b\c" read state clear echo -e "Zipcode: \b\c" read zip echo -e "Telephone: \b\c" read phone echo "$first:$last:$m:$street:$city:$state:$zip:$phone" >> store_data.txt echo -e "Any more to add? (Y)es or (N)o> _\b\c" read answer case $answer in [Yy]* ) answer=y ;; * ) answer=n ;; esac done ...thanks.

when u run the program for the first time, add 1000 as ID and keep adding one each time it runs.. i haven't tested this piece of code but u can work around to it... tail -2 store_data.txt| head -1 | awk -F :'{print $1}' | read return expr $return + 0 >/dev/null 2>&1 if [ $? -ne 0 ] then id=1000 else if [ $return -gt 0 -a $return -lt 9999999 ] then id=$return+1 fi echo "$id:$first:$last:$m:$street:$city:$state:$zip:$phone" >> store_data.txt Regards, Devaraj Takhellambam

Thanks a lot Fidy, I will try to run the code tom..

inlcude this piece of code tail -1 store_data.txt | awk -F: '{print $1}'| read return expr $return + 0 >/dev/null 2>&1 if [ $? -ne 0 ] then id=1000 elif [ $return -gt 0 -a $return -lt 9999999 ] then id=`expr $return + 1` fi echo $id Regards, Devaraj Takhellambam

Thanks for your help. On the same application i have to search the person with the id i entered.and display the info only by id.I will post the code on the search part, thanks again.

I need some help please. I did try the code above but it didn't work. Can someone tell me what am i doing wrong. Thanks. return=`tail -1 store_data.txt | awk -F : '{ print $1 }'` if [ $return == "" ] then id=1000 else if [ $return -gt 0 -a $return -lt 9999999 ] then id=`expr $return + 1` fi fi
