True Bourne shell:

So I think zsh is OK in this case.

Here's the culprit in the script:

This isn't a very portable script in the first place.  A better test for
a variable being unset would be:


	if [ -z "$APS_BASEDIR" ]; then

beta 19 cannot run this script

I had to link /bin/sh to zsh in order to make automatic tex font
generation work. However, zsh (called as sh), doesn't run this script:

#! /bin/sh

The error is:

You need to double quote variable otherwise the shell will just
evaluate it and there is no argument as indicated by the shell.  I
think that bash is just a quirk that it works.  Normally, ksh, regular
sh, this will fail, unless you double quote it.

#! /bin/sh
if [ -z "$APS_BASEDIR" ]; then
        APS_BASEDIR=`grep APS_BASEDIR /etc/printcap | cut -d ':' -f 2`
        export APS_BASEDIR

Hmmm...

I tried this and it doesn't work :-(

Trying with this small version:

#! /bin/sh
if [ -z $APS_BASEDIR ]; then
	APS_BASEDIR=`grep APS_BASEDIR /etc/printcap | cut -d ':' -f 2`
	export APS_BASEDIR
fi

I get

./foo: [: argument expected [2]

So there seems to be something wrong...

SOLVED: beta 19 cannot run this script

[Carlos Carvalho]

Umpf shame :-(

Bart's correction does work fine (of course). Sorry for the missing
quotes. I've only got about 999 replies up to now...
