||) Logical OperatorContinues next operation only if previous operation fails
When in the normal run mode (see “schedulers” link below) this will only run the command on the right hand side if the command on the left hand side does not error. Neither STDOUT nor STDERR are piped.
This has no effect in try nor trypipe run modes because they automatically apply stricter error handling. See detail below.
Second command does not run because the first command doesn’t error:
» out: one || out: two
oneSecond command does run because the first command produces an error:
» err: one || out: two
one
twoThis has no effect in try nor trypipe run modes because they automatically apply stricter error handling. You can achive a similiar behavior in try with the following code:
try {
err: one -> !if { out: two }
}There is no workaround for trypipe.
