Dear listmembers,
installing SRSS 4.2EA on my Debian server I realized that using
http://wiki.sun-rays.org/images/f/f5/95SUNW-pulseaudio.txt or similar
scripts requires installing ksh and a line on top of the script that
is to be put in /etc/X11/Xsessions.d/ as follows:
#!/usr/bin/ksh
Otherwise
# sed "s|UTAUDIODEV|$UTAUDIODEV|g" /usr/local/bin/utpulse.pa >
${PULSECONF}
will not work because the default bash shell throws an error message
and does not insert the current variable; using slashes instead of
the pipe signs results in bash only in a literally inserted
$UTAUDIODEV.
Cost me an hour or two to figure it out, perhaps this could be
updated in the respective Wikis. With ksh the script works very well.
Greetings,

I think from memory the last time I did an install of Sun Ray on
Debian (SRSS 4.1 on Stable/Lenny), the installation script for SRSS
aborted unless I already had ksh installed in the first place (it does
a check).
Is that possible why it's never had a shebang added to the first line
of that script?
Those scripts do say "#!/bin/sh" at the start. The point was to use the
least-common-denominator shell, and that's typically /bin/sh. Bourne
shell and ksh both expand variables in double-quotes. So does bash:
bash-3.00$ A=foo
bash-3.00$ echo foobar | sed "s/$A/blech/"
blechbar
bash-3.00$ echo foobar | sed "s|$A|blech|"
blechbar
As you can see above, pipes or slashes are used shouldn't matter - sed
will use whatever the character that follows the 's' in its substitution
command, and it doesn't appear that bash does anything strange with '|'
in double-quotes. Maybe you have a new version of bash that is now
handling '|' or variable-expansion in double-quotes differently? Maybe
this is a bug in your Debian release?
