How do I run a system command and capture the output with Julia?

How do I run a system command and capture the output with Julia?

In R I could do this with something like system_output <- system2("ls","-l", stdout=TRUE, stderr=TRUE)

Use the read function with a Cmd object. The docstrings are a little hard to find, so here they are:

read(command::Cmd)

Run command and return the resulting output as an array of bytes.

read(command::Cmd, String)

Run command and return the resulting output as a String.

For example, if you want to get the output of ls -l as a string, you would run

read(`ls -l`, String)

The backticks create the Cmd object, which is executed by read.
