Can't run help commands in docker/alpine because imcompatible less options

[sir-gon]

I'm getting this output trying to see wp-cli help.

/var/www/html # wp --allow-root help
less: unrecognized option: r
BusyBox v1.24.2 (2016-11-01 12:56:05 GMT) multi-call binary.

Usage: less [-EIMmNSh~] [FILE]...

View FILE (or stdin) one screenful at a time

	-E	Quit once the end of a file is reached
	-I	Ignore case in all searches
	-M,-m	Display status line with line numbers
		and percentage through the file
	-N	Prefix line number to each line
	-S	Truncate long lines
	-~	Suppress ~s displayed past EOF

I'm running in a custom images based on php:7-fpm-alpine.
Googling, I found the same issue in this (another) project: pry/pry#1494 (comment)

They has a workaround, but is possible to make wp-cli more compatible?

Have you tried setting the PAGER environment variable?

See

wp-cli/php/commands/help.php

Line 96 in cd4d6e2

if ( false === ( $pager = getenv( 'PAGER' ) ) ) {

[sir-gon]

Yes, i'm using the following to run a shell of my docker:

docker exec -it www_php_1 /bin/sh -c "export TERM=xterm; export PAGER='busybox less'; exec sh"

Works, but... is just a workaround.

[danielbachhuber]

Ok. That's what the PAGER environment variable is there for.

For those of you suffering from garbled output when using busybox less as a value for the PAGER env variable, use more instead. Works beautifully!

I resolved that way:
Running directly into container apk add --update less
and after I updated my Dockerfile adding less \ into RUN apk update && apk add --no-cache \
