The loop that dosent work
I have a serious problem and Im sure im just doing something stupid

Code:
######Start Load 
while [ `< /export/home/mldwh/rkem_refresh/int_load/logs/iteration.log` -lt 15 ]
do
         /export/home/mldwh/rkem_refresh/int_load/scripts/rkem_refresh.sh
         sleep 10
         while [ -a /export/home/mldwh/rkem_refresh/int_load/logs/int_rkem_move_running.txt ]
         do 
   					sleep 5 
				done
done


######Log and Runstats 
sleep 10
echo "2nd 15 iterations finished" >> /export/home/mldwh/rkem_refresh/int_load/logs/Int_master.log
echo 0 > /export/home/mldwh/rkem_refresh/int_load/logs/iteration.log
db2 "CALL SYSPROC.ADMIN_CMD('runstats on table CENDW.DW_RKEM_MOVE_TBL with distribution and detailed indexes all shrlevel change')" >> /export/home/mldwh/rkem_refresh/int_load/logs/Int_master.log
db2 "CALL SYSPROC.ADMIN_CMD('runstats on table CENDW.DW_RKEM_MOVE_UPDATE_TBL with distribution and detailed indexes all shrlevel change')" >> /export/home/mldwh/rkem_refresh/int_load/logs/Int_master.log
sleep 10


######Start Load 
while [ `< /export/home/mldwh/rkem_refresh/int_load/logs/iteration.log` -lt 15 ]
do
         /export/home/mldwh/rkem_refresh/int_load/scripts/rkem_refresh.sh
         sleep 10
         while [ -a /export/home/mldwh/rkem_refresh/int_load/logs/int_rkem_move_running.txt ]
         do 
   					sleep 5 
				done
done

What I want to do is run the .sh file 15 times and then do some stuff and then run the .sh file 15 times again. I put the loop inside the loop (where i think my problem is) to make sure that the outer loop waited untill the .sh file was done before calling it again.

But what I am getting......ohh man this thing is spawning so many instances of the code that I have to chmod -x just to stop it.

So where am i going wrong?

What shell are you running that in? - it's not valid bourne at any rate...

you specified a while loop that do repetition if some counter is less than 15. Where is the counter? I presume its the value in the iteration.log file and int_rkem_move_running.txt files? if it is, then you have to update them to reflect a new counter everytime.

The counter is in the iteration.log file and it is incrmented durring the last step of the .sh file

the int_rkem_move_running.txt is a "seed" file that is created at the begining of the .sh script and deleted at the end of the .sh script.

The iteration seems to work I see it loop, but for some reason it seems to call the .sh file many times before it finishes. I.E. the loop isnt waiting for the .sh to finish before it calls another one.

I dont get it....

I'm just noting that those two lines I quoted are not valid in bourne - thus prompting the question of which shell.

The `< file` thing is unique to ksh as far as I can tell and is an aliase for wc
The -a makes no sense to me at all - I'm used to it being a logical and between two expressions.
