printed: hello | sort. How, then, does one construct a pipeline? Instead of using '|' inside of backticks, one uses pipeline: julia> run(pipeline(`echo hello`, `sort`)); hello This pipes the output there's only one line to sort, but we can certainly do much more interesting things: julia> run(pipeline(`cut -d: -f3 /etc/passwd`, `sort -n`, `tail -n5`)) 210 211 212CHAPTER 27. RUNNING EXTERNAL PROGRAMS process. Julia lets you pipe the output from both of these processes to another program: julia> run(pipeline(`echo world` & `echo hello`, `sort`)); hello world In terms of UNIX plumbing, what's happening
