+.Sh FREQUENTLY ASKED QUESTIONS
+This FAQ attempts to document some of the questions users of
+.Nm
+or readers of this manual page may encounter.
+.Ss I'm an Android user, so what's mksh?
+.Nm mksh
+is a
+.Ux
+shell / command interpreter, similar to
+.Nm COMMAND.COM
+or
+.Nm CMD.EXE ,
+which has been included with

+for a while now.

+be asked to do by other programs, even in the background.
+Any privilege pop-ups you might be encountering are thus not

+issues but questions by some other program utilising it.
+.Ss "I'm an OS/2 user, what do I need to know?"
+Unlike the native command prompt, the current working directory is

+systems (the shell is designed for Unix-like systems); if you really
+need this, run the command
+.Li PATH=".;$PATH"
+or add that to a suitable initialisation file.
+.Pp
+You will have gotten this shell through komh's port on Shellworld
+most likely. It differs from standard mksh in that ASCII (CR+LF)
+newlines are accepted in many places.
+.Ss "How do I start mksh on a specific terminal?"
+Normally:
+.Dl mksh \-T/dev/tty2
+.Pp
+However, if you want for it to return (e.g. for an embedded
+system rescue shell), use this on your real console device instead:
+.Dl mksh \-T!/dev/ttyACM0
+.Pp
+.Nm
+can also daemonise (send to the background):
+.Dl mksh \-T\- \-c \*(aqexec cdio lock\*(aq
+.Ss "POSIX says..."
+Run the shell in POSIX mode (and possibly
+.Nm lksh
+instead of
+.Nm mksh ) :
+.Dl set \-o posix
+.Ss "My prompt from <some other shell> does not work!"
+Contact us on the mailing list or on IRC, we'll convert it for you.
+.Ss "Something is going wrong with my while...read loop"
+Most likely, you've encountered the problem in which the shell runs
+all parts of a pipeline as subshell.
+The inner loop will be executed in a subshell and variable changes
+cannot be propagated if run in a pipeline:

+.Ss "What differences in function-local scopes are there?"
+.Nm
+has a different scope model from
+.At
+.Nm ksh ,
+which leads to subtle differences in semantics for identical builtins.
+This can cause issues with a
+.Ic nameref
+to suddenly point to a local variable by accident.
+.Pp
+.Tn GNU
+.Nm bash
+allows unsetting local variables; in
+.Nm ,
+doing so in a function allows back access to the global variable
+(actually the one in the next scope up) with the same name.
+The following code, when run before the function definitions, changes
+the behaviour of
+.Ic unset
+to behave like other shells (the alias can be removed after the definitions):
+.Bd -literal -offset indent
+case ${KSH_VERSION:\-} in
+*MIRBSD\ KSH*\*(Ba*LEGACY\ KSH*)
+	function unset_compat {
+		\e\ebuiltin typeset unset_compat_x
+
+		for unset_compat_x in "$@"; do
+			eval "\e\e\e\ebuiltin unset $unset_compat_x[*]"
+		done
+	}
+	\e\ebuiltin alias unset=unset_compat
+	;;
+esac
+.Ed
+.Pp
+When a local variable is created (e.g. using
+.Ic local ,
+.Ic typeset ,
+.Ic integer ,
+.Ic \e\ebuiltin typeset )
+it does not, like in other shells, inherit the value from the global
+(next scope up) variable with the same name; it is rather created
+without any value (unset but defined).
+.Ss "I get an error in this regex comparison"
+Use extglobs instead of regexes:
+.Dl "[[ foo =~ (foo\*(Babar).*baz ]]	# becomes"
+.Dl "[[ foo = *@(foo\*(Babar)*baz* ]]	# instead"
+.Ss "Are there any extensions to avoid?"
+.Tn GNU
+.Nm bash
+supports
+.Dq Li &\*(Gt
+.Pq and Dq Li \*(Ba&
+to redirect both stdout and stderr in one go, but this breaks POSIX
+and Korn Shell syntax; use POSIX redirections instead:
+.Dl "foo \*(Ba& bar \*(Ba& baz &\*(Gtlog			     # GNU bash"
+.Dl "foo 2\*(Gt&1 \*(Ba bar 2\*(Gt&1 \*(Ba baz \*(Gtlog 2\*(Gt&1	# POSIX"
+.Ss "\*(haL (Ctrl-L) does not clear the screen"
+Use \*(ha[\*(haL (Escape+Ctrl-L) or rebind it:
+.Dl bind \*(aq\*(haL=clear-screen\*(aq
+.Ss "\*(haU (Ctrl-U) clears the entire line"
+If it should only delete the line up to the cursor, use:
+.Dl bind \-m \*(haU=\*(aq\*(ha[0\*(haK\*(aq
+.Ss "Cursor Up behaves differently from zsh"
+Some shells make Cursor Up search in the history only for
+commands starting with what was already entered.
+.Nm
+separates the shortcuts: Cursor Up goes up one command
+and PgUp searches the history as described above.
