# guesswidth
[](https://pkg.go.dev/github.com/noborus/guesswidth) [](https://github.com/noborus/guesswidth/actions/workflows/build.yml)
## Overview
guesswidth guesses the column position for fixed-width formats(fwf).
The output of the `ps` command has no delimiters, making the values difficult to machine-readable.
guesswidth guesses smarter than just space delimiters.
guesswidth is guessed based on the position of characters in the **header**.
So having a header will give you better results.
## Install command
There is also a guesswidth command.
```console
go install github.com/noborus/guesswidth/cmd/guesswidth@latest
```
Guess the width output with no delimiters in the command.
```console
$ ps
PID TTY TIME CMD
302965 pts/3 00:00:12 zsh
733211 pts/3 00:00:00 ps
733212 pts/3 00:00:00 tee
733213 pts/3 00:00:00 guesswidth
```
Split the output like this:
```console
$ ps | guesswidth
PID| TTY | TIME|CMD
302965| pts/3 | 00:00:08|zsh
539529| pts/3 | 00:00:00|ps
539530| pts/3 | 00:00:00|guesswidth
```
It can be converted to `csv`.
```console
$ ps | guesswidth csv
PID,TTY,TIME,CMD
302965,pts/3,00:00:12,zsh
733211,pts/3,00:00:00,ps
733212,pts/3,00:00:00,tee
733213,pts/3,00:00:00,guesswidth
```
##
## Examples
guesswidth inserts a delimiter (| by default)
(Colors are changed here for clarity).
Even if there are spaces in the header or body, they will be separated correctly.
### ps
### docker ps
### docker node
