Package: bash
Version: 4.1-3
Severity: normal
Text equivalency should use '==' (as per man page and before Deb 6),
but now needs '='.
Parameter expansion as per man page uses ${param:start:length} and worked prior
to Debian 6, but now fails miserably.
--------------Example code follows for file test.sh--------------
#!/bin/sh
# Execute via "sh test.sh"
#
# Note that Bash' manual says '==' is used to test for
# string (in)equality. It used to work, but now does not.
#
# The Parameter Expansion section of the Bash man page says
# that ${parameter:offset:length} is the correct format
# to extract a substring. It used to work, but now does
# not.
A="asd"
if [ $A = "asd" ]; then # Why must '==' be '=' to work correctly?
echo "EQUAL"
else
echo "NOT EQUAL"
fi
R=$(/sbin/runlevel)
echo "runlevel = $R"
S=${R:2:1} # What is wrong with this?
echo "runlevel is actually $S"
-------------end of example code illustrating bad behaviour-----
