detach
detach(command)
Mark a command object so that it will be run in a new process group, allowing it to outlive the julia process, and not have Ctrl-C interrupts passed to it.
Examples
-
Detach a command in a new process group:
julia> detach(`sleep 10`) Command(`sleep 10`, ProcessExited(0))
This example detaches the command
sleep 10
in a new process group, allowing it to run independently of the Julia process. -
Detach a command with arguments:
julia> detach(`echo "Hello, world!"`) Command(`echo "Hello, world!"`, ProcessExited(0))
It detaches the command
echo "Hello, world!"
with arguments and executes it in a separate process group. - Detach a command and handle the process exit status:
julia> result = detach(`ls non-existent-file`) Command(`ls non-existent-file`, ProcessExited(2)) julia> result.status 2
This example detaches the command
ls non-existent-file
and captures the process exit status in theresult
variable.
Common mistake example:
julia> detach(`non-existent-command`)
ERROR: could not spawn `non-existent-command`: no such file or directory (ENOENT)
In this example, the command provided does not exist, resulting in an error. Make sure to provide a valid command that can be executed in a separate process group using detach
.
