If condition error-please debug my script

- It would be very helpful if you post the error.
- The set -x before the shebang should be redundant and can be left out. Shebang should be 1st in your script and afterwards you can tell the shell what to do.
- There is a typo in your comment: "clreate" should be "create" I guess.
- For the awk question, the basic field separator is any number of any kind of concatenated spaces. So a single blank should be in most cases just not needed to be specified as field separator. If it produces what you want, it is ok. Can't see any syntax error.
- Good you use CODE tags but intendation would be nice too
- In the lines where you use the variable $d you might want to write ${d} since it's position is close to other characters. For better readability and for protection against neighbouring characters.
- Things like "cat $file|head -1" are unnecessary since you could just write "head -1 $file" and leave the cat out.
I don't see more atm since it's early in the morning. Maybe fix the one or other thing mentioned above and show the errors you get please.
