This is valid ksh syntax....
Code:
$ cat num
10
$ echo $(< num)
10
$ echo `< num`
10
$ [ -a num ] && echo ok
ok
$

$(< num) is the contents of the file called num. I have seen this often. I have never seen `< num` before and it is not documented, but it seems to work. Many versions of ksh allow -a or -e to test if an item is a file sysetm object of any kind (not just a file, not just a directory, not just a symlink, etc). But -e and -a are not super standard even among versions of ksh.

i think its also benefiical if you show your other .sh scripts as well.

I agree about needing more info. A loop must initialize a loop counter, increment it, and test it. I see one script that sets /export/home/mldwh/rkem_refresh/int_load/logs/iteration.log to zero. And another that tests it. No increment though. And I do not see how these script fragments inter-relate. Smilie

also, using kill -15 is a better way to stop a runaway program than to do a chmod -x on something.

I was hopeing not to burden you with all the ugly details of the other .sh but you asked for it Smilie

Code:
#!/bin/bash -x

######Capture MainFrame Time
RKEM_Mainframe_time $RKEM_LOG rkem_master.log $IDB1USER $IDB1PWD


######Set Master Date Variable
Master_date $RKEM_LOG rkem_master.log


######Audit Process Start
Process_Audit_Start $RKEM_LOG rkem_master.log $TPCUSER $TPCPWD $MASTERDATE "'RKEM REFRESH'" 'Start RKEM Delta Load'


######Start Full Process File
echo -==Create Start and Stop files==- >> $RKEM_LOG"rkem_master.log"
db2 -x "select rtrim(char(year(max(CHDATETIME)))) || '-' || substr( digits (month(max(CHDATETIME))),9) || '-' || substr( digits (day(max(CHDATETIME))),9) From CENDW.DW_RKEM_MOVE_TBL" > $RKEM_LOG"rkem_start_date.txt"
db2 -x "select substr( digits (hour(max(CHDATETIME))),9) || '.' || substr( digits (minute(max(CHDATETIME))),9) || '.' || substr( digits (second(max(CHDATETIME))),9) From CENDW.DW_RKEM_MOVE_TBL" > $RKEM_LOG"rkem_start_time.txt"
echo -== Start Date `cat $RKEM_LOG"rkem_start_date.txt"`==- >> $RKEM_LOG"rkem_master.log"
echo --==Start time `cat $RKEM_LOG"rkem_start_time.txt"`==- >> $RKEM_LOG"rkem_master.log"


######Create Hold File for RKEM Load Process
Hold_File $RKEM_LOG rkem_master.log 'RKEM MOVE DELTA REFRESH RUNNING' int_rkem_move_running.txt


######Call RKEM MOVE Extract PROCESS
RKEM_Call_Process $RKEM_LOG rkem_master.log $RKEM_SCRIPT extract_rkem_move.sh 'Start RKEM Process'


sleep 15


######Call RKEM MOVE Load PROCESS
RKEM_Call_Process $RKEM_LOG rkem_master.log $RKEM_SCRIPT load_rkem_move.sh 'Call $RKEM_SCRIPT"load_rkem_move.sh"'


######Wait for RKEM MOVE PROCESS to Complete
File_Wait $RKEM_LOG rkem_master.log rkem_move_delta_running.txt 'Start time waiting for STG RKEM to load' 'Finish time waiting for STG RKEM to load'


######Test that Load completed
Process_Test $RKEM_LOG rkem_master.log "'RKEM REFRESH'" "'RKEM REFRESH - RKEM MOVE'" $MASTERDATE $RKEM_SCRIPT merge_rkem_move.sh 'RKEM STG LOAD INCOMPLETE' INCOMPLETE_RKEM_STG_LOAD.TXT


sleep 15


######Wait for RKEM MOVE MERGE PROCESS to Complete

######Test that Merge completed
Process_Test $RKEM_LOG rkem_master.log "'RKEM REFRESH'" "'RKEM REFRESH - MERGE RKEM MOVE'" $MASTERDATE $RKEM_SCRIPT merge_rkem_move_update.sh 'RKEM MOVE MERGE INCOMPLETE' INCOMPLETE_RKEM_MOVE_MERGE.TXT


sleep 15


######Wait for RKEM MOVE MERGE UPDATE PROCESS to Complete

######Test that Update Merge completed

sleep 15


######Wait for RKEM MOVE UPDATE PROCESS to Complete
File_Wait $RKEM_LOG rkem_master.log rkem_move_update_running.txt 'Start time waiting for RKEM MOVE UPDATE ' 'Finish time waiting for RKEM MOVE UPDATE'


######Test that Update completed
Last_Process_Test $RKEM_LOG rkem_master.log "'RKEM REFRESH'" "'RKEM REFRESH - UPDATE'" $MASTERDATE 'RKEM MOVE UPDATE INCOMPLETE' INCOMPLETE_RKEM_MOVE_UPDATE.TXT


######Audit FULL PROCESS
Process_Audit_Stop $RKEM_LOG rkem_master.log $TPCUSER $TPCPWD "'RKEM REFRESH'" 'Finish RKEM Delta Load'


######Set Iteration Log
value=`< /export/home/mldwh/rkem_refresh/int_load/logs/iteration.log`
final=`expr $value + 1`
echo $final > /export/home/mldwh/rkem_refresh/int_load/logs/iteration.log


######Remove Hold File for RKEM Load
Remove_Hold_file $RKEM_LOG rkem_master.log int_rkem_move_running.txt

Notice near the bottom where I set the iteration log

Code:
######Set Iteration Log
value=`< /export/home/mldwh/rkem_refresh/int_load/logs/iteration.log`
final=`expr $value + 1`
echo $final > /export/home/mldwh/rkem_refresh/int_load/logs/iteration.log

Does this shed more light onto the problem? Im realy behind on a deadline and I need this loop to work so that I can enjoy the vacation that I am on. Any info would be great
