How to capture the output of a Julia script while the script is running in a shell?-CodePudding

I can capture the output of a julia script in the shell with the > operator, for example:

$ julia script.jl > output.txt

However, it seems that the file is only written to after the julia script finished. For example, if script.jl contains the following code:

println("Hello world!)
sleep(10)

then output.txt is created immediately, but the Hello world! appears in the file only after 10 seconds.

Is there a way to immediately write the Julia output to the file as soon as each command is executed and not wait for the script to finish?

CodePudding user response：

println("Hello world!")
flush(stdout)
sleep(10)

So the output isn't buffered.

For instance by

stdbuf -o0 julia script.jl > output.txt
