Not sure if this is related, but i'd love to see more scripting languages (mostly Python) offer facilities which let them take over from shell script for more scripts and one-liners.

Think about what it would take to write this in Python right now:

  for wmv_file in $(find $1 -name '*.wmv'); do
    echo -n "${wmv_file} "
    ffmpeg -i $wmv_file ${wmv_file%.wmv}.mpg 2>&1 | grep kb/s: || echo "ERROR $?"
  done
With a few handy variables and functions predefined, this could be something like:

  for wmv_file in find(argv[1], glob="\*.wmv"):
    print(wmv_file, end=" ")
    result = do("ffmpeg", "-i", wmv_file, basename(wmv_file, ".wmv") + ".mpg")
    if result: print(grep(str(result), "kb/s:"))
    else: print("ERROR", result.status)

How about

  for wmv in Path(sys.argv[1]).rglob("\*.wmv"):
        print(wmv, end=" ")
        r = subprocess.run(
            ["ffmpeg", "-i", wmv, wmv.with_suffix(".mpg")],
            stdout=subprocess.PIPE, stderr=subprocess.STDOUT,
        )
        lines = [l for l in r.stdout.decode().splitlines() if "kb/s:" in l]
        print("\n".join(lines) if lines else f"ERROR {r.returncode}")
?

If you go outside stdlib you can use the sh library instead of subprocess.run.

Ruby does a pretty good job, with `system` and backticks. The FileUtils module actually defines some nice helpers like `mv`, `cp` and `ln_s`. So you can do `cp "/tmp/a.txt", filename`. And you can get a list of files matching a glob with `Dir["/tmp/*.txt"]`.

I think Perl is what you're looking for!
