Iglesias" Errors-To: qemu-devel-bounces+patchwork-qemu-devel=patchwork.kernel.org@nongnu.org Sender: "Qemu-devel" X-Virus-Scanned: ClamAV using ClamSMTP POSIX says that backslashes in the arguments to 'echo', as well as any use of 'echo -n' and 'echo -e', are non-portable; it recommends people should favor 'printf' instead. This is definitely true where we do not control which shell is running (such as in makefile snippets or in documentation examples). But even for scripts where we require bash (and therefore, where echo does what we want by default), it is still possible to use 'shopt -s xpg_echo' to change bash's behavior of echo. And setting a good example never hurts when we are not sure if a snippet will be copied from a bash-only script to a general shell script (although I don't change the use of non-portable \e for ESC when we know the running shell is bash). Replace 'echo -n "..."' with 'printf "..."', and 'echo -e "..."' with 'printf "...\n"'. In the qemu-iotests check script, also fix unusual shell quoting that would result in word-splitting if 'date' outputs a space. Signed-off-by: Eric Blake Reviewed-by: Edgar E.
