Shell Programming and Scripting

I have access to a large unix parallel computing cluster. To submit jobs I simply run a script called "submit" followed by options relevant to that particular job. Very simple and easy, "submit" can be run from any directory.

I am trying to make a batch file that automatically runs "submit" in multiple directories. I essentially would like to elminate manually submiting jobs manually, because I may have 100's of jobs to submit.

The stucture is simple: /case*/job

Manually I would type the commands:

cd Case1
submit options
cd ..
cd Case2
submit options
cd ..
etc.

HOpefully this makes sense. It seems like it should be an easy problem to solve, but nothing I have done seems to work.

A simple batch file? Those run under MS-DOS and Windows.

Is the computer you are running on Linux or another UNIX-like system? If so then you probably want a shell script. It's more than just picky terminology--words mean things.

Anyway, how about this?

Code:

#!/bin/sh
cd /home/cpabrego/Case1
submit options
cd /home/cpabrego/Case2
submit options
cd /home/cpabrego/Case3
submit options

The first line, #!/bin/sh (or #!/bin/bash) declares this to be a shell script and tells what command processor to use. The other lines are just the commands you want to execute. I assume you have some submit command installed.

Thanks for the reply!

Yes I meant to say shell script. The system is a UNIX system, Submit is also a shell script as you mention that I am using to submit jobs. I think the code you proposed will work I can test it.

However, because the number of case directories will vary, I would like to make the script more flexible. The number of cases varies from as few 5 to 100's and varies.

Is this possible?

That depends on the real directory names and options. If they really are generic like that, then this might work.

Code:

#!/bin/sh
LIMIT=100
n=0
while test $n -lt $LIMIT; do
    cd /home/cpabrego/Case$n
    submit options
    ((n++))
done

or maybe this:

Code:

#!/bin/sh
DIRS="Case1 Case2 Case3 Case4 Case5"
DIRS="$DIRS Case6 Case7 Case8 Case9"

for d in $DIRS; do
    cd /home/cpabrego/$d
    submit options
done

Thanks for the info. The options for submit are strait forward and are in the form: submit -n 8 filename. Where file name will be constant in every case*.

One thing you pointed out will come into play. The directories will actually be called:
case001
case002
...etc
Which is a bit more complicated. Is this the same thing?

Code:

#!/bin/sh
DIRS="Case*"
DIRS="$DIRS"
 
for d in $DIRS; do
    cd /home/cpabrego/$d
    submit options
done

You have given me a great starting point, I will try your ideas and let the forum what works for me.

Thanks for the replies, a late update I finally found time to run the scripts and for my needs this worked best.

Code:

 
#!/bin/sh
DIRS="case*"
DIRS="$DIRS"
for d in $DIRS; do
    cd $d
    submit options
    cd ..
done
