Cheers again :) That seems to work although it returns each line multiple times, meaning the output file becomes much larger than the original

That's closer yes... although, I've highlighted above where records are out of line:

9025:11:35 - this should sit between 9025:19:10 and 9025:09:43

989:13:42 - this should be above 989:08:56

Thanks for the uber-fast reply Krish. I looked at the key definition thing (k switch) but it didn't seem to to work either. Using what you gave does the right thing, only, when I transpose that...

My pleasure ;)

Cheers, I wondered if cron was the best option. Thanks for the confirmation/advice

Hi,

I have a script I want to run as a background process. Where would I add a bit of script so that a check can be performed to see it this is already running and, where it isn't, to then run it?...

Hi,

Copy and paste this when you have used 'cd' to change into the directory you want to work on:

Hi,

Using nohup it sends output automatically to $HOME/nohup.out - how do I direct this output to another named file instead, so I can run several scripts in the background at once, directing...

How is this error resolved please?

I'm just trying to run a shell script and am getting this error. All file permissions are fine.

Thanks
