Enhanced bhist source code

One of popular batch scheduler in Supercomputing area is LSF. As many other forks out there, I used LSF for a while until we switched to other one. bhist is one of LSF command to displays historical information about jobs.

I was assigned to develop a shell script to display job list consumed more than certain wall time clock of certain user. So, I've got 2 input parameters; wall clock time and user id. And output should be the list of jobs used more than given wall time clock and it should contain detail information about job. Finally, the output should be suitable for printing and reporting.

This is what I came up with after spending one or two days. To align column or row for printing layout, it includes lots of intentional tabs and white spaces.

Here is sample output;
