I am running a bteq command in UNIX and I want bteq output to be displayed on stdout and also be logged to a file using unix 'tee' command. Also I intend to check the bteq return code and take necessary action. Here is the code snippet -
When bteq throws an error the "if" logic is supposed to evaluate to true and the program should exit. However, the return code check below is not working because it is in effect evaluating the return code of the 'tee' command (which is executed after bteq) and not evaluating the return code of the bteq, which executes before 'tee'. So the return code check always evaluates to 'true' even when the bteq command returns a non-zero exit status.
Is there any way to circumvent this problem ? I want to display the output of bteq on stdout and redirect to a file and also check the return code of bteq (and not that of tee).

I'm preparing for exam and one of exams is to write own test command...
I wonder if in unix is a command which just returns exit code you specify..
I know I can easily write a function like this:
exStatus() {
return $1
}
-> my question is rather theoretical
thank you! (9 Replies)
hi,
exit status variable $?, returns some digits.
0 ---> succes.
1..126
Failure (the program itself will decide what the numbers mean)
127
Command not found
128..254
The program did not exit normally. (E.g., it crashed, or received a signal)
255
Invalid exit code
well, if $?... (4 Replies)
