computer doesn't recognise changes in my script

Reignfire · 09-27-2012, 04:46 AM

Hi,

When i change some code in my script and save it, the computer always runs the old script as if i didn't save the file. Only when i save it to another name it works. How can i fix that problem?

Some basic information that I think you should have included in your post:
What distro?
What script language?
What editor are you using?
How are you calling the script?

I think i has something to do with the file getting stucked in the cache of my RAM and doesn't get refreshed. It's on a debian distro, it happends to al kinds of script languages. The code is right that's not the problem cause sometimes it does work. I'm running the code on a compute cluster (several servers working as one in a grid engine)

And what basic checking have you done? Maybe as simple as:

1. Write simple script
2. Cat file to check same as when saved
3. Run script and check results
4. Edit script
5. See 2
6. See 3

Sometimes when I'm running code on an NFS client, I notice that updated versions of shared libraries aren't being used - every time I've noticed it, doing a quick "ls /path/to/libdir" or "ls libname.so" does the trick (I assume because it's forcing the system to see if the file handle is stale). Maybe you could try making a simple script that lists/cats the script before executing it.

You may have a duplicate script.sh somewhere, 1 in your path and one not.

Code:

sudo find `pwd` / -name script.sh -type f

Change script.sh to actual script name.

You didn't answer these questions.

More details probably needed also for the "computer cluster" - what filesystem is it?

After saving, does ls or stat see an updated timestamp immediately?
