🐛 [BUG] - readlink: unrecognized option: m

[c33s]

Description

running the script on alpine/busybox fails with the following error:

readlink: unrecognized option: m
BusyBox v1.35.0 (2022-11-19 10:13:10 UTC) multi-call binary.

Usage: readlink [-fnv] FILE

Display the value of a symlink

        -f      Canonicalize by following all symlinks
        -n      Don't add newline
        -v      Verbose

Reproduction steps

on `alpine:3.17.0` run:

bash inline.sh --in-file test.sh

test.sh

#!/bin/ash

echo "hello"
source header.sh

header.sh

# fail on non-zero exit code
set -e -o pipefail -o errexit

OS

Alpine Linux Busybox

hopefully helpful links:

• readlink has no -e option on busybox/alpine, realpath has no options at all basherpm/basher#49
• busybox readlink does not support '-m' BernieO/calcardbackup#4
