Bug in "expr"

[Jay McGuerty]

Hi,
I am using CentOS v5.3  BASH v3.2.25(1)  and get an error when I use the
"expr" command
to extract characters and it encounters a space.   It returns the correct
value - just sends an
error as well..... this appears to be a bug....

# echo $slime
three blind mice
char=`expr ${slime:4:1}`
# echo $char
e
# char=`expr ${slime:5:1}`
expr: missing operand
Try `expr --help' for more information.
# echo $char

#
