dash incompatibility in /etc/profile

dash incompatibility in /etc/profile

[Charles Wilson]

Running 'dash -l' flags an error in /etc/profile:

if [[ -n ${BASH_VERSION} ]]; then
  HOSTNAME=$(/usr/bin/hostname)
  profile_d sh
  [[ -f "/etc/bash.bashrc" ]] && . "/etc/bash.bashrc"
elif [[ -n ${KSH_VERSION} ]]; then
  typeset -l HOSTNAME=$(/usr/bin/hostname)
  profile_d sh
  PS1=$(print
'\033]0;${PWD}\n\033[32m${USER}@${HOSTNAME}\033[33m${PWD/${HOME}/}\033[0m\n$
')
elif [[ -n ${ZSH_VERSION} ]]; then
  HOSTNAME=$(/usr/bin/hostname)
  profile_d zsh
  PS1='(%n@%m)[%h] %~ %% '


these uses of '[[' are not supported by dash, although apparently posh
supports them.

I was trying to launch 'dash' from cmd.exe, in such a way that the
default Windows values of TMP, TMPDIR, and TEMP were overridden.  For
now I can do

> set ENV=~/.dashinit
> dash

but...can we use /bin/test or a regular '[' here?

Hello,

Can you please check which version of base-files here you using?
In 4.0-6 I have:

if [ ! "x${BASH_VERSION}" = "x"  ]; then
  HOSTNAME=$(/usr/bin/hostname)
  profile_d sh
  [ -f "/etc/bash.bashrc" ] && . "/etc/bash.bashrc"
elif [ ! "x${KSH_VERSION}" = "x" ]; then
  typeset -l HOSTNAME=$(/usr/bin/hostname)
  profile_d sh
  PS1=$(print '\033]0;${PWD}\n\033[32m${USER}@${HOSTNAME}
\033[33m${PWD/${HOME}/~}\033[0m\n$ ')
elif [ ! "x${ZSH_VERSION}" = "x" ]; then
  HOSTNAME=$(/usr/bin/hostname)
  profile_d zsh
  PS1='(%n@%m)[%h] %~ %% '
elif [ ! "x${POSH_VERSION}" = "x" ]; then
  HOSTNAME=$(/usr/bin/hostname)
  PS1="$ "
else
  HOSTNAME=$(/usr/bin/hostname)
  profile_d sh
  PS1="$ "
fi

As per:

4.0-6
    * Dropped non-POSIX tests in /etc/profile - Eric Blake

Maybe you modified /etc/profile preventing it to get updated before 4.0-6.

I guess I must have done so, but I don't remember doing it.  I'll update
from /etc/defaults/ and see what "breaks" because the default files are
missing whatever mods I made.
