[Texmacs-dev] /bin/sh vs. /bin/bash in Ubuntu

[Andrea Gamba]

Dear Joris,

can you fix also the old  /bin/sh - /bin/bash problem, that still 
hampers the use of external mathematical programs in Ubuntu 8.10? See:
https://launchpad.net/ubuntu/+source/texmacs/+bug/58498
and also:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=497020
https://savannah.gnu.org/bugs/?18519
https://bugs.launchpad.net/ubuntu/+source/texmacs/+bug/181315
https://bugs.launchpad.net/ubuntu/+source/texmacs/+bug/70655

I know there was a long discussion about it. At the end of the story, I 
think there are two easy solutions:

1) change /bin/sh -> /bin/bash in the first row of all shell scripts in 
/usr/local/libexec/TeXmacs/bin/, that should still be good for all 
distributions;

2) do it in a distribution-dependent way, i.e. only for the Ubuntu and 
Debian package (although the problem is only in Ubuntu, there is usually 
a single package for both.)

Other solutions are more complicated.

Apart from the /bin/sh - /bin/bash problem:

The Octave plugin hangs TeXmacs at start. The fix is to change 
tm-start.oct and .octaverc in  
/usr/local/share/TeXmacs/plugins/octave/octave/ as follows:

gset -> __gnuplot_set__
LOADPATH=[[...,LOADPATH]] -> addpath([[...]])
PS1=... -> PS1(...)
PS2=... -> PS2(...)

to take into account changes in the Octave script language (that are 
listed by typing "new" at the Octave prompt). See:
https://bugs.launchpad.net/ubuntu/+source/texmacs/+bug/181315

Unfortunately, the list of broken plugins (at least in Ubuntu) is not 
exhausted here. I would like to contribute to improve the situation, is 
it ok to go on posting plugin-related patches here?
