OpenFOAM 4.0, bad option -t in zsh

Hello everybody,

I'm in the process of passing from OF 3.0.1 to OF 4.0. Meanwhile I also changed my shell from bash to zsh + OMZ since that is the shell I naturally use on my personal machines.

I'm experiencing a problem with the initial setup of the environment, in particular:

Code:

source OpenFOAM-4.0/etc/bashrc

returns an error:

Code:

OpenFOAM-4.0/etc/config.sh/aliases:73 bad option -t

I had no issues with OF3.0.1. In facts if we check the two different bashrc configuration scripts:

OpenFOAM 4.0

OpenFOAM 3.0.x

in the new version we have:

Code:

[ "$(type -t wmRefresh)" = "alias" ] && unalias wmRefresh || unset wmRefresh

The type builtin has different arguments in bash and in zsh

bash

Code:

type

 type [-afptP] [name …]

zsh

Code:

type [ -wfpamsS ] name ...



# Equivalent to whence -v

In particular no -t option is available. In zsh the most similar command to type -t would be, I guess, type -w (that prints a <name>: <type> string instead of just <type> as for bash's type command).
I'm not a shell ninja, but anyone among you knows a cross-platform solution to this bug?

Just replace the line that includes the -t option with this one:

[ "$(type wmRefresh | awk '{print $4}')" = "alias" ] && unalias wmRefresh || unset wmRefresh

I found the answer here.

Thanks for your help. What I did was:

Code:

[[ "$(type wmRefresh)" =~ "alias" ]] && unalias wmRefresh || unset wmRefresh

that should be portable also with bash. Basically looking for the word "alias" in the output of type. In bash it should print something like 'wmRefresh aliased to' and it should validate correctly. Didn't check though.

Working in zsh shell

Here is the update on this.

Replace this L73: in etc/configh.sh/aliases :

Code:

[ "$(type -t wmRefresh)" = "alias" ] && unalias wmRefresh || unset wmRefresh

with this:

Code:

# For backward-compatibility unalias wmRefresh if it is defined as an alias

if declare -f wmRefresh > /dev/null

then

    unset wmRefresh

else

    unalias wmRefresh 2> /dev/null

fi

Cheers
:)
