Batch loop - rese_support - 11-Jan-2018
Quote:I am wondering if it is possible to 'for' loop the PARGE or ATCOR commands?
Say if I have the following commands:
..\idlrt.exe -rt="..\atcor4.sav" -args "filename_1" F
..\idlrt.exe -rt="..\atcor4.sav" -args "filename_2" F
...
..\idlrt.exe -rt="..\atcor4.sav" -args "filename_n" F
I can write this within a for loop in the command window.
However, the problem is running PARGE/ATCOR takes a while.
Each command should be started after the previous command is finished.
Say, filename_2 has to wait until filename_1 finishes.
So, how do I tell it to 'wait'?
For a batch loop, you got various options:
- use IDL (if you got an IDL license) and write a script for the various calls
- use a third party programming language and issue the calls in for-loop
- write a windows .bat script
For the latter, you got to make sure that tasks are completed (there are some tricks for that, but I didn't test this).
Alternatively, there shouldn't be a problem starting things in parallel as long as the processes are started in separated directories.
