Why script is running sometimes and not running sometimes?

Shell Programming and Scripting

Hi,

I have a script which does couple of database connection and run some SELECT queries to get some output in the file.

I am surprised to see :eek: that when i run my script some times it gives the desired out put and sometimes it shows some error :confused: .

Suppose if i execute it say 5 times 3 times it gives the output and 2 times not

Note: I don't do any change to the script. Just keep on executing it without any change

Can someone help on this??

i am working in KSH

Thanks

Posting details like script, output, environment and error messages will help us help you.

If the script is doing something like generating an output in the working directory, it may generate different results each time you execute the script.

Just guessing because a few days ago it just happened to me and this kept me busy for a few minutes until I realised why the output was so different each time without doing any changes "apparently".

Above that, it could be a number of reasons why that's happening. It's difficult to guess if no details are given.

You've given us a puzzle a bit like:-

  • My car runs fine
  • Sometimes it doesn't

What's wrong?

You might need to give us a bit more information to have much chance of helping you here, such as the code (wrapped in & tags) along with some sample output and any error messages.

Give us a clue, please :confused:
