Or Logical Operator
Continues next operation only if previous operation fails
Description
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.
Examples
Second command does not run because the first command doesn't error:
» out one || out two
one
Second command does run because the first command produces an error:
» err one || out two
one
two
Detail
This has no effect in try
nor trypipe
run modes because they automatically apply stricter error handling. You can achieve a similar behavior in try
with the following code:
try {
err one -> !if { out two }
}
There is no workaround for trypipe
.
