Go port of moreutils/ts
MIT License
tss
is like ts
from moreutils, but prints relative durations (with
millisecond precision) by default, and can be shipped as a compiled binary.
Try it out:
$ (sleep 1; echo "hello"; sleep 2; echo "two sec") | tss
995ms hello
3s 2.005s two sec
The first column is the amount of time that has elapsed since the program started. The second column is the amount of time that has elapsed since the last line printed.
Find your target operating system (darwin, windows, linux) and desired bin directory, and modify the command below as appropriate:
curl --silent --location --output /usr/local/bin/tss https://github.com/kevinburke/tss/releases/download/0.4/tss-linux-amd64 && chmod 755 /usr/local/bin/tss
The latest version is 0.4.
If you have a Go development environment, you can also install via source code:
go get -u github.com/kevinburke/tss
The corresponding library is available at
github.com/kevinburke/tss/lib
. View the library documentation at
godoc.org.
Piping commands to tss
may result in programs buffering their output before
flushing it to stdout file descriptor. You can avoid this by wrapping the target
program in a command like unbuffer
(via the expect package) or
stdbuf
from the coreutils package. On Macs you can install with
brew install expect
and brew install coreutils
respectively; the stdbuf
command may be prefixed with a 'g': gstdbuf
.
stdbuf --output=L <mycommand> | tss
Piping commands may also change the return code from non-zero to zero, since
Bash by default uses the return code of the last command in the pipe to decide
how to exit. This means if you are piping output to tss
or ts
you may
accidentally change a failing program to a passing one. Use set -o pipefail
in
Bash scripts to ensure that Bash will return a non-zero return code if any part
of a pipe operation fails. Or add this to a Makefile:
SHELL = /bin/bash -o pipefail
