FWIW, I think the only issue with $ ~/.plenv/bin/plenv is that non-POSIX "here-strings" and other unnecessary Bash-isms (from 4.x +?) are used.

Here is an overview of the changes I made to make it a a bit more portable:

Oddly complicated?

#read READLINK < <( type -p greadlink readlink ) || {
  #echo "plenv: cannot find readlink - are you missing GNU coreutils?" >&2
  #exit 1
#}

Becomes:

READLINK=`type -p readlink`
export READLINK

This seems like the hard way here, perhaps I am missing something:

#export -n CDPATH
unset CDPATH

Use typeset (ksh) instead of local (Bash-ism):

:%s/local /typeset /gc

Really lazy hack

:%s/^shopt/# /

I also changed the shebang to ksh93 as a proof-of-concept:

#!/usr/bin/env ksh

Maybe when I have some time I will look into trying to make it POSIX-compliant.

from plenv.
