The exit 1
Fi

Can be used while/until cycle, but you're going to check all the time? Ok files, execution stops the script?

Yeah! Scenario is, I need to other systems of dat file loaded into our database, if you don't have judgment ok file is loaded will run empty, then all wrong

CodePudding user response:

I wrote this
If [-f "$fileok"]; Then
SQLLDR...
Fi

So write words, it does not exist when the program is run out, at the back of the program will continue to run

While 1 & gt; 0
Do
If [-f "$fileok"]
Then
SQLLDR
The exit
The else
Sleep 100
The continue
Fi
The done

You set a sleep time, had better not too short, because there is no ok files, will always cycle, time is too short, be afraid influence server
