: evaluates in POSIX shells to the result of /usr/bin/true or true.
It is used like that to override a return status value that would affect subsequent processing.
For example, in Appworx (a batch control system) a false return code almost anywhere is detectable, so that if ||: were not there at the end of a line, appworx may see a false return and abort the job when the child process returns. Even though the job may have completed correctly.
Don't ask how, I'd have to guess.
