The script that you have assumes that you are trying to create a semicolon separated values line of output for each group of input lines that have insert_job: in the first line of the group and that the output you want contains values found in fields named: insert_job, box_name, command, owner, permission, condition, description, std_out_file, std_err_file, and alarm_if_fail. It also assumes that there is no more than one field per input line.

Besides not looking for more than one field per line, it does not look for job_type, machine, date_conditions, days_of_week, or start_times.

Do you still want a semicolon separated values file?

Do you know what fields you want to appear in your output file?

Do you need a program that will search for all of the field names that appear in your input file(s) and then produce a semicolon separated output file with a heading line showing every field found and then print a line for each input record found? If that is what you want, how is the program supposed to determine record boundaries?

What type of system are you using?

What is the value of {LINE_MAX} on your system? (I.e., what is the output from the command: getconf LINE_MAX?)

How big is (are) your input file(s)?
