||
Or 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
one
Second command does run because the first command produces an error:
» err one || out two
one
two
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
.

Elvis Operator:
Returns the right operand if the left operand is falsy (expression)?
stderr Pipe:
Pipes stderr from the left hand command to stdin of the right hand
