Package: bash Version: 3.1-1 Hi,
please have a look at the following lines:
] [EMAIL PROTECTED]:~> echo $LOGNAME
] nordholz
] [EMAIL PROTECTED]:~> echo ${LOGNAME[0]}
] nordholz
] [EMAIL PROTECTED]:~> echo ${LOGNAME[$(( 0 ))]}
] nordholz
] [EMAIL PROTECTED]:~> echo ${LOGNAME[$(( 0*0 ))]}
] nordholz
] [EMAIL PROTECTED]:~> echo ${LOGNAME[$(( 0+0 ))]}
] nordholz
Ok, works as expected... but now:
] [EMAIL PROTECTED]:~> echo ${#LOGNAME[$(( 0 ))]}
] 8
] [EMAIL PROTECTED]:~> echo ${#LOGNAME[$(( 0*0 ))]}
] 8
] [EMAIL PROTECTED]:~> echo ${#LOGNAME[$(( 0+0 ))]}
] -bash: ${#LOGNAME[$(( 0+0 ))]}: bad substitution
Further testing proved that '*' and '**' are the only
accepted arithmetic operators in such an expansion...
is there a special reason for that?
I've confirmed this behaviour with the latest
stable (2.05b-26) and the current testing/unstable
version (3.1-1) of bash.
I'll try to research the problem ( == come up with
a patch), but my schedule is rather full, so I
can't make any promises.
Regards,
Jan
