How to launch multiple Julia runs one after another?

General Usage
1

I have 25 *.jl files that need to be run one after another. Each of them could take an extended amount of time.

Is there a way I can create a master_run.jl file and tell Julia to run these 25 jl files one after another. Something like the below?

run A01.jl
run A02.jl
...
run A25.jl

Thanks.

Put in your master_run.jl file the following

run(`julia A01.jl`)
run(`julia A02.jl`)
...
run(`julia A25.jl`)

Many thanks!

Unfortunately, I got the below error:
ERROR: LoadError: IOError: could not spawn A01.jl: no such file or directory (ENOENT)

The master_run.jl file and the rest of the jl files are in the same directory.

This is what I do:

mzaffalon@NBFAE01-6CS3PF2 MINGW64 ~/test
$ ls
A01.jl  A02.jl  master_run.jl 

mzaffalon@NBFAE01-6CS3PF2 MINGW64 ~/test
$ cat master_run.jl
run(`julia A01.jl`)
run(`julia A02.jl`)

mzaffalon@NBFAE01-6CS3PF2 MINGW64 ~/test
$ julia

Many thanks! It is working now.

I turns out I missed the ‘julia’ part inside the parentheses.
