Package: mksh Version: 50d-5 Severity: minor Dear Maintainer,
here is a note in manpage about [ $foo = bar ] equality test: $ MANWIDTH=78 LC_ALL=C man mksh 2>>/dev/null <&2 | grep -A5 'A common mistake is to use' Note: A common mistake is to use ``if [ $foo = bar ]'' which fails if parameter ``foo'' is NULL or unset, if it has embedded spaces (i.e. IFS octets), or if it is a unary operator like '!' or '-n'. Use tests like ``if [ x"$foo" = x"bar" ]'' instead, or the double-bracket operator ``if [[ $foo = bar ]]'' or, to avoid pattern matching (see [[ above): ``if [[ $foo = "$bar" ]]'' the proposed [ x"$foo" = x"bar" ] is correct but with redundant x character; this x looks odd and attracts attention, while proper quotation is the point in order to make it clear it should be something like [ "$foo" = bar ] -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: armhf (armv7l) Foreign Architectures: armel Kernel: Linux 3.0.35-ygrex-fx6-6.3+ (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages mksh depends on: ii libc6 2.19-18 mksh recommends no packages.
