rtss annotates its output with relative durations between consecutive lines and
since program start.
It can be used as a filter in a pipeline:
-% cargo build --release 2>&1 | rtss
261.7ms 261.6ms | Compiling rtss v0.2.0 (file:///home/freaky/code/rtss)
3.02s 2.76s | Finished release [optimized] target(s) in 3.1 secs
3.02s exit code: 0
It can also directly run commands, annotating both stdout and stderr with durations.
stdin is passed through to the child process, and its exit code will become rtss'
own exit code:
``` -% rtss sh -c "echo foo; echo bar; sleep 1; echo moo >&2; sleep 1; echo baz; exit 64" 1.7ms 0.8ms | foo 1.7ms 42.5μs | bar 1.07s 1.06s # moo 2.07s 2.07s | baz 2.07s exit code: 64 zsh: exit 64 rtss sh -c
-% rtss sh -c "echo foo; echo bar; sleep 1; echo moo >&2; sleep 1; echo baz; exit 64" 2>/dev/null 1.6ms 1.0ms | foo 1.6ms 51.1μs | bar 2.06s 2.06s | baz 2.06s exit code: 64 zsh: exit 64 rtss sh -c ```
The core of rtss; copying one IO to another with timestamps, and pretty-printing
Durations, is exposed as a library for use in other programs.
If you have Cargo installed you can install the latest release with:
cargo install rtss
You can also install the latest bleeding-edge version using:
cargo install --git https://github.com/Freaky/rtss.git
Alternatively you can clone and build manually without installing:
git clone https://github.com/Freaky/rtss.git &&
cd rtss &&
cargo build --release &&
target/release/rtss echo It works
rtss was inspired by Kevin Burke's tss.
Both are basically trendier versions of ts from moreutils.
