I'm pretty new to shell scripting, but I am catching on quick. I did see one of the stickied threads about the csh, and I think this is relevant, but I don't understand enough to make a decision based on it. So as you'll see below, I use the |csh pipe, and if that is not correct, I'm certainly open to learning how to change it.
I maintain a list of jobs that I've submitted to the server (this is just a file I create and update). I can pull up a list of jobs that are in the queue or running. My goal is to grab the list of running/queued jobs, and compare that to the my list, and output the jobs that are no longer in the queue (meaning they've completed).
So grab the lines from my static file (curJobs.log), and pull the 2nd field which contains the jobID. Then pull up the list of running jobs, and see if that jobID is found with grep. If it is not found, then echo that job ID.
The output then is (2nd line is a jobID, but not the correct one):
Code:
if: Expression Syntax.
348240
This is in fact just the very first job in the list, it is not the correct result.
I have tried so many different iterations of the if statement trying to find the correct format, and I have not succeeded. I've read through the gawk if statement tutorial where they use if ( x % 2 == 0), and such, I've tried to format in similar ways. With and without ` or ", and I am sure I'm missing some fundamental understanding of how I'm to combine these pieces.
Any guidance in solving this problem would be greatly appreciated
HI again, still working on the assignment, which is really hard given we just started unix 4 weeks ago.

Hello, I am getting Expression syntax message and I cannot figure out what's wrong. This program will print all the odd numbers between 0 and the one the user enters, in cshell.

Hi
what's the correct way of writing if
1)if "$time_diff" -gt 5
then
echo "killing hung process \n"
fi
2)if test $time_diff -gt 5
then
echo "killing hung process \n"
fi
where -time_diff=$(($Sam - $current_min))
and current_min=`date +%M`
infact both are giving Syntax... (1 Reply)
Hello,
This is my first post so, Hello World! Anyways, I'm learning how to use unix and its quickly become apparent that a strong foundation in regular expressions will make things easier. I'm not sure if my syntax is messing things up or my logic is messing things up.

STANDARD OUTPUT
Displaying Job Status
If the -a, -i, -f, -r, -u, -n, -G, and -M options are not specified, the brief single-line display format is used. The following items are
displayed on a single line, in the specified order, separated by white space:
the job id
the job name
the job owner
the cpu time used
the job state
C - Job is completed after having run E - Job is exiting after having run. H - Job is held. Q - job is queued, eligible to run or
routed. R - job is running. T - job is being moved to new location. W - job is waiting for its execution time (-a option) to be
reached. S - job is suspended.
the queue that the job is in
If the -f option is specified, the multi-line display format is used. The output for each job consists of the header line: Job Id: job
identifier followed by one line per job attribute of the form: attribute_name = value
If any of the options -a, -i, -r, -u, -n, -G or -M are specified, the normal single-line display format is used. The following items are
displayed on a single line, in the specified order, separated by white space:
the job id
the job owner
the queue the job is in
the job name
the session id (if the job is running)
the number of nodes requested by the job
the number of cpus or tasks requested by the job
the amount of memory requested by the job
either the cpu time, if specified, or wall time requested by the job, (in hh:mm)
the job state
The amount of cpu time or wall time used by the job (in hh:mm)
EXIT STATUS
On success, qstat will exit with a value of zero. On failure, qstat will exit with a value greater than zero.
