Hi everyone,

I am not really a scripter by nature but now have the need to create one that handles sequential numbering.

Basically I need the script to create a sequential number everytime its run. I dont expect anyone to tell me how to do it as i want to learn. I just need some pointers for where to start.

Thanks in advance

Well after having a coffee, i figured it out. So incase anyone else needs this i have added the little script below:

#!bin/bash
#
# Get number from file, increment by one
# then append file
#
CODE=XW-R-
COUNTER="`tail -1 /incrementregister`"
INCREMENT="`expr $COUNTER + 1`"
RETURNSNUMBER="$CODE`expr $COUNTER + 1`"
echo $RETURNSNUMBER >> /returnsregister
echo "NEW RETURNS NUMBER:"
tail -1 /returnsregister
echo $INCREMENT >> /incrementregister
echo "NEW INCREMENT NUMBER:"
tail -1 /incrementregister
echo "Both above numbers should match"


And if anyone wonders what i needed this for, it will be accessed by procmail when certain emails come in. Then those emails will be autoreplied with the new returns number in the subject line.

Thanks
