C Shell - Traversing a file


I am currently trying to write a C Shell script that informs the user when a processing job has finished. I have a file that can be continually updated about the processing jobs.


When the job is in progress the file looks like this

Job id Name User Time Use S Queue
------------------- ---------------- --------------- -------- - -----
3962.master MM-PBEPBE juanp 1150:19: R verylong
3964.master MM-PBE1PBE juanp 1069:31: R verylong
3987.master MMC-SVWN5 juanp 660:32:0 R verylong
4031.master MM-9-PBEPBE juanp 304:06:5 R verylong
4032.master MM-9-PBE1PBE juanp 303:58:4 R verylong
4033.master MM-9-HSE1PBE juanp 54:08:48 R verylong
4034.master MM-9-B3LYP juanp 20:30:58 R verylong
4076.master MM-HF juanp 03:21:22 R verylong
4077.master MM-HSE1PBE juanp 0 Q verylong
4110.master ...ex1-1.7-ULSDA thuk 120:19:1 R verylong
4145.master ...1.87-UHSE1PBE thuk 23:21:48 R verylong
4149.master Cusp-H karl 0 Q short

And when the job has finished, it looks like this

Job id Name User Time Use S Queue
------------------- ---------------- --------------- -------- - -----
3962.master MM-PBEPBE juanp 1150:19: R verylong
3964.master MM-PBE1PBE juanp 1069:31: R verylong
3987.master MMC-SVWN5 juanp 660:32:0 R verylong
4031.master MM-9-PBEPBE juanp 304:06:5 R verylong
4032.master MM-9-PBE1PBE juanp 303:58:4 R verylong
4033.master MM-9-HSE1PBE juanp 54:08:48 R verylong
4034.master MM-9-B3LYP juanp 20:30:58 R verylong
4076.master MM-HF juanp 03:21:22 R verylong
4077.master MM-HSE1PBE juanp 0 Q verylong
4110.master ...ex1-1.7-ULSDA thuk 120:19:1 R verylong
4145.master ...1.87-UHSE1PBE thuk 23:21:48 R verylong

With the bottom entry missing.

How would I write a C Shell scipt to inform me, or be able to proceed with other instructions when the the file no longer contains the bottom entry.

Start by looking up the man pages for "tail" and "grep". Maybe also "sleep".
