Re: Logical expression works does not work as expected

[Павел Fortovey]

   I apologize. I found out that this behavior is not a bug.

   I didn't think that bash is such a strange scripting language with its
   own interpretation of the concept of logic.

   Patch Level: 15

   Release Status: release



   Description:

          in a logical expression of the form "true && true || false &&
   false" the first two are executed, but unexpectedly the last value
   "false" is executed. i.e. the command "printf 1 && printf 2 || printf 3
   && printf 4" will give "124" instead of the expected answer "12"

   Repeat-By:

           bash -c "true && true || false && echo bug"
