The current check is broken, as it only checks if the user's login shell is bash, not what the system shell is. Mimick the sequence found in the top-level Makefile to search for bash, except for the fallback case, where we explicitly check that 'sh' is bash, by checking if it sets $BASH, so we know the fallback case, in the top-level Makefile, to use 'sh' will indeed use bash. Remove superfluous semi-colons ';' at the end of lines, they are not needed in a shell script (this is not C!) Signed-off-by: "Yann E.
