[Bug 210425] [NEW] firefox uses wrong shell to call /etc/init.d/xprint

[Hadmut Danisch]

Public bug reported:

Binary package hint: firefox

Hi,

when starting firefox from the command line, you'll get a syntax error
message:

/etc/init.d/xprint: 531: Syntax error: Bad substitution


Reason:

/usr/lib/firefox/run-mozilla.sh calls /etc/init.d/xprint :

    if [ -f /etc/init.d/xprint ] ; then
        XPSERVERLIST="`/bin/sh /etc/init.d/xprint get_xpserverlist`"
    ...

so it uses /bin/sh to execute /etc/init.d/xprint

/etc/init.d/xprint uses the extended shell syntax of bash.

on my system: 
lrwxrwxrwx 1 root root 4 2007-08-11 23:52 /bin/sh -> dash*

and dash does not understand bash syntax.

So it is wrong to call /bin/sh /etc/init.d/xprint


Proposal:

first check whether /etc/init.d/xprint is executable. If so, call it directly. 
If not, use /bin/sh.

regards
Hadmut
