--- Begin Message ---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----- -- System Information: Debian Release: 6.0.1 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: i386 (i686) Kernel: Linux 2.6.32-5-686 (SMP w/2 CPU cores) Locale: LANG=en_CA.utf8, LC_CTYPE=en_CA.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages bash depends on: ii base-files 6.0squeeze1 Debian base system miscellaneous f ii dash 0.5.5.1-7.4 POSIX-compliant shell ii debianutils 3.4 Miscellaneous utilities specific t ii libc6 2.11.2-10 Embedded GNU C Library: Shared lib ii libncurses5 5.7+20100313-5 shared libraries for terminal hand Versions of packages bash recommends: ii bash-completion 1:1.2-3 programmable completion for the ba Versions of packages bash suggests: pn bash-doc <none> (no description available) -- no debconf information

I suspect it isn’t Yeah, this report was specific to lenny-to-squeeze upgrades, and I agree that that ship has sailed. Closing. Thanks for writing, Jonathan
