Executing External Programs in Julia

Code

In Julia, the run() function is used to execute a string wrapped in backticks `. This is similar to using the os.system() from the os module in Python.

julia> txt = "helloworld"
"helloworld"

julia> typeof(`echo $txt`)
Cmd

위와 같이 백틱으로 감싸진 문자열은 Cmd라는 타입을 가지고, run() 함수로써 실행할 수 있다.

julia> run(`cmd /C echo $txt`)
helloworld
Process(`cmd /C echo helloworld`, ProcessExited(0))

Limited to this example, on Windows, it becomes a bit complicated as you have to execute echo within cmd, but on Linux, you can simply use echo $txt. If you frequently use such commands on Windows, consider modifying the environment variables¹.

Environment
