lsr#

ls(1) but with io_uring

Installation#

lsr uses the zig build system. To install, you will need zig 0.14.0. To install for the local user (assuming $HOME/.local/bin is in $PATH), run:

zig build -Doptimize=ReleaseSmall --prefix $HOME/.local

which will install lsr and the associated manpage appropriately. Replace $HOME/.local with your preferred installation directory.

Usage#

lsr [options] [directory]

  --help                           Print this message and exit
  --version                        Print the version string

DISPLAY OPTIONS
  -1, --oneline                    Print entries one per line
  -a, --all                        Show files that start with a dot (ASCII 0x2E)
  -A, --almost-all                 Like --all, but skips implicit "." and ".." directories
  -C, --columns                    Print the output in columns
      --color=WHEN                 When to use colors (always, auto, never)

  -l, --long                       Display extended file metadata

Benchmarks#

Benchmarks were all gathered on the same set of directories, using the latest releases of each program (versions are shown below). All benchmarks run on Linux (because io_uring). lsr does work on macOS/BSD as well, but will not see the syscall batching benefits that are available with io_uring.

Time#

Data gathered with hyperfine on a directory of n plain files.

Syscalls#

Data gathered with strace -c on a directory of n plain files. (Lower is better)
