UNIX for Dummies Questions & Answers

I am checking one until loop with the following logic

until [ $job_status_ftp = $job_status_etl = $job_status_db = "SUCCESS" ]||
[ $job_status_db = "FAILURE" ]||[ $job_status_etl = "FAILURE" ]|| [ $job_status_ftp = "FAILURE" ]
do
sleep 30
done

before running this i am exporting above variables to SUCCESS.But the loop is running in infinite loop.My requirement is to make the loop run until
all the 3 variables are SUCCESS or any of the 3 variables is FAILURE.
Evan if the condition is satisfied the loop is running.

Furhter i am getting
[: =: unexpected operator/operand
error while running.Cn any one please check the code and let me know where is the issue

Try this instead,

Code:

until [ "$job_status_ftp" = "SUCCESS" -a "$job_status_etl" = "SUCCESS" -a "$job_status_db" = "SUCCESS" ] ||
      [ "$job_status_db" = "FAILURE" -o "$job_status_etl" = "FAILURE" -o "$job_status_ftp" = "FAILURE" ]
 do
   sleep 30
 done

Note - nothing inside the loop (sleep 30) will ever change the value of your variables
It can loop forever, depending on the variables' values.
