From mboxrd@z Thu Jan 1 00:00:00 1970 From: Petr Vorel Date: Thu, 17 Dec 2020 13:15:19 +0100 Subject: [LTP] [PATCH 1/2] docparse/parse.sh: Fix parsing on dash In-Reply-To: <20201217121520.25713-1-pvorel@suse.cz> References: <20201217121520.25713-1-pvorel@suse.cz> Message-ID: <20201217121520.25713-2-pvorel@suse.cz> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ltp@lists.linux.it bash keeps escape sequences (e.g. \t and \n) when using echo: $ a="-v\tverbose output\n"; echo "$a" -v\tverbose output\n $ But dash interprets them (behaves like echo -e on bash): $ a="-v\tverbose output\n"; echo -e "$a" -e -v verbose output $ Using printf does not help, because it'd have to be separated with -- which cannot be used for printing variables. Fortunately cat << EOF redirection is portable. In the future we should probably avoid shell as much as possible.
