--	 * expanding an alias, the value of the alias is pushed back on the
--	 * input as a string and a pointer to the alias is stored with the
--	 * string.  The alias is marked as being in use.  When the input
--	 * routine finishes reading the string, it markes the alias not
--	 * in use.  The problem is synchronization with the parser.  Since
--	 * it reads ahead, the alias is marked not in use before the
--	 * resulting token(s) is next checked for further alias sub.  The
--	 * H A C K is that we add a little fluff after the alias value
--	 * so that the string will not be exhausted.  This is a good

-+.Sh NAME
-+.Nm printf
-+.Nd formatted output
-+.Sh SYNOPSIS
-+.Nm
-+.Ar format
-+.Op Ar arguments  ...
-+.Sh DESCRIPTION
-+.Nm
-+formats and prints its arguments, after the first, under control
-+of the
-+.Ar format  .
-+The
-+.Ar format
-+is a character string which contains three types of objects: plain characters,
-+which are simply copied to standard output, character escape sequences which
-+are converted and copied to the standard output, and format specifications,
-+each of which causes printing of the next successive
-+.Ar argument  .
-+.Pp
-+The
-+.Ar arguments
-+after the first are treated as strings if the corresponding format is
-+either
-+.Cm b ,
-+.Cm c
-+or
-+.Cm s ;
-+otherwise it is evaluated as a C constant, with the following extensions:
-+.Pp
-+.Bl -bullet -offset indent -compact
-+.It
-+A leading plus or minus sign is allowed.
-+.It
-+If the leading character is a single or double quote, the value is the
-+.Tn ASCII
-+code of the next character.
-+.El
-+.Pp
-+The format string is reused as often as necessary to satisfy the
-+.Ar arguments  .
-+Any extra format specifications are evaluated with zero or the null
-+string.
-+.Pp
-+Character escape sequences are in backslash notation as defined in
-+.St -ansiC .
-+The characters and their meanings
-+are as follows:
-+.Bl -tag -width Ds -offset indent
-+.It Cm \ee
-+Write an \*[Lt]escape\*[Gt] character.
-+.It Cm \ea
-+Write a \*[Lt]bell\*[Gt] character.
-+.It Cm \eb
-+Write a \*[Lt]backspace\*[Gt] character.
-+.It Cm \ef
-+Write a \*[Lt]form-feed\*[Gt] character.
-+.It Cm \en
-+Write a \*[Lt]new-line\*[Gt] character.
-+.It Cm \er
-+Write a \*[Lt]carriage return\*[Gt] character.
-+.It Cm \et
-+Write a \*[Lt]tab\*[Gt] character.
-+.It Cm \ev
-+Write a \*[Lt]vertical tab\*[Gt] character.
-+.It Cm \e\'
-+Write a \*[Lt]single quote\*[Gt] character.
-+.It Cm \e\e
-+Write a backslash character.
-+.It Cm \e Ns Ar num
-+Write an 8-bit character whose
-+.Tn ASCII
-+value is the 1-, 2-, or 3-digit
-+octal number
-+.Ar num .
-+.El
-+.Pp
-+Each format specification is introduced by the percent character
-+(``%'').
-+The remainder of the format specification includes,
-+in the following order:
-+.Bl -tag -width Ds
-+.It "Zero or more of the following flags:"
-+.Bl -tag -width Ds
-+.It Cm #
-+A `#' character
-+specifying that the value should be printed in an ``alternative form''.
-+For
-+.Cm c  ,
-+.Cm d ,
-+and
-+.Cm s  ,
-+formats, this option has no effect.  For the
-+.Cm o
-+formats the precision of the number is increased to force the first
-+character of the output string to a zero.  For the
-+.Cm x
-+.Pq Cm X
-+format, a non-zero result has the string
-+.Li 0x
-+.Pq Li 0X
-+prepended to it.  For
-+.Cm e  ,
-+.Cm E ,
-+.Cm f  ,
-+.Cm g ,
-+and
-+.Cm G  ,
-+formats, the result will always contain a decimal point, even if no
-+digits follow the point (normally, a decimal point only appears in the
-+results of those formats if a digit follows the decimal point).  For
-+.Cm g
-+and
-+.Cm G
-+formats, trailing zeros are not removed from the result as they
-+would otherwise be;
-+.It Cm \&\-
-+A minus sign `\-' which specifies
-+.Em left adjustment
-+of the output in the indicated field;
-+.It Cm \&+
-+A `+' character specifying that there should always be
-+a sign placed before the number when using signed formats.
-+.It Sq \&\ \&
-+A space specifying that a blank should be left before a positive number
-+for a signed format.  A `+' overrides a space if both are used;
-+.It Cm \&0
-+A zero `0' character indicating that zero-padding should be used
-+rather than blank-padding.  A `\-' overrides a `0' if both are used;
-+.El
-+.It "Field Width:"
-+An optional digit string specifying a
-+.Em field width ;
-+if the output string has fewer characters than the field width it will
-+be blank-padded on the left (or right, if the left-adjustment indicator
-+has been given) to make up the field width (note that a leading zero
-+is a flag, but an embedded zero is part of a field width);
-+.It Precision :
-+An optional period,
-+.Sq Cm \&.\& ,
-+followed by an optional digit string giving a
-+.Em precision
-+which specifies the number of digits to appear after the decimal point,
-+for
-+.Cm e
-+and
-+.Cm f
-+formats, or the maximum number of characters to be printed
-+from a string; if the digit string is missing, the precision is treated
-+as zero;
-+.It Format :
-+A character which indicates the type of format to use (one of
-+.Cm diouxXfwEgGbcs ) .
-+.El
-+.Pp
-+A field width or precision may be
-+.Sq Cm \&*
-+instead of a digit string.
-+In this case an
-+.Ar argument
-+supplies the field width or precision.
-+.Pp
-+The format characters and their meanings are:
-+.Bl -tag -width Fl
-+.It Cm diouXx
-+The
-+.Ar argument
-+is printed as a signed decimal (d or i), unsigned octal, unsigned decimal,
-+or unsigned hexadecimal (X or x), respectively.
-+.It Cm f
-+The
-+.Ar argument
-+is printed in the style
-+.Sm off
-+.Pf [\-]ddd Cm \&. No ddd
-+.Sm on
-+where the number of d's
-+after the decimal point is equal to the precision specification for
-+the argument.
-+If the precision is missing, 6 digits are given; if the precision
-+is explicitly 0, no digits and no decimal point are printed.
-+.It Cm eE
-+The
-+.Ar argument
-+is printed in the style
-+.Sm off
-+.Pf [\-]d Cm \&. No ddd Cm e No \\*(Pmdd
-+.Sm on
-+where there
-+is one digit before the decimal point and the number after is equal to
-+the precision specification for the argument; when the precision is
-+missing, 6 digits are produced.
-+An upper-case E is used for an `E' format.
-+.It Cm gG
-+The
-+.Ar argument
-+is printed in style
-+.Cm f
-+or in style
-+.Cm e
-+.Pq Cm E
-+whichever gives full precision in minimum space.
-+.It Cm b
-+Characters from the string
-+.Ar argument
-+are printed with backslash-escape sequences expanded.
-+.It Cm c
-+The first character of
-+.Ar argument
-+is printed.
-+.It Cm s
-+Characters from the string
-+.Ar argument
-+are printed until the end is reached or until the number of characters
-+indicated by the precision specification is reached; however if the
-+precision is 0 or missing, all characters in the string are printed.
-+.It Cm \&%
-+Print a `%'; no argument is used.
-+.El
-+.Pp
-+In no case does a non-existent or small field width cause truncation of
-+a field; padding takes place only if the specified field width exceeds
-+the actual width.
-+.Sh EXIT STATUS
-+.Nm
-+exits 0 on success, 1 on failure.
-+.Sh SEE ALSO
-+.Xr echo 1 ,
-+.Xr printf 3 ,
-+.Xr printf 9
-+.Sh STANDARDS
-+The
-+.Nm
-+utility conforms to
-+.St -p1003.2-92 .
-+.Sh BUGS
-+Since the floating point numbers are translated from
-+.Tn ASCII
-+to floating-point and
-+then back again, floating-point precision may be lost.

-+.Sh NAME
-+.Nm test ,
-+.Nm \&[
-+.Nd condition evaluation utility
-+.Sh SYNOPSIS
-+.Nm test
-+.Ar expression
-+.Nm \&[
-+.Ar expression Cm ]
-+.Sh DESCRIPTION
-+The
-+.Nm test
-+utility evaluates the expression and, if it evaluates
-+to true, returns a zero (true) exit status; otherwise
-+it returns 1 (false).
-+If there is no expression, test also
-+returns 1 (false).
-+.Pp
-+All operators and flags are separate arguments to the
-+.Nm test
-+utility.
-+.Pp
-+The following primaries are used to construct expression:
-+.Bl -tag -width Ar
-+.It Fl b Ar file
-+True if
-+.Ar file
-+exists and is a block special
-+file.
-+.It Fl c Ar file
-+True if
-+.Ar file
-+exists and is a character
-+special file.
-+.It Fl d Ar file
-+True if
-+.Ar file
-+exists and is a directory.
-+.It Fl e Ar file
-+True if
-+.Ar file
-+exists (regardless of type).
-+.It Fl f Ar file
-+True if
-+.Ar file
-+exists and is a regular file.
-+.It Fl g Ar file
-+True if
-+.Ar file
-+exists and its set group ID flag
-+is set.
-+.It Fl h Ar file
-+True if
-+.Ar file
-+exists and is a symbolic link.
-+.It Fl k Ar file
-+True if
-+.Ar file
-+exists and its sticky bit is set.
-+.It Fl n Ar string
-+True if the length of
-+.Ar string
-+is nonzero.
-+.It Fl p Ar file
-+True if
-+.Ar file
-+is a named pipe
-+.Po Tn FIFO Pc .
-+.It Fl r Ar file
-+True if
-+.Ar file
-+exists and is readable.
-+.It Fl s Ar file
-+True if
-+.Ar file
-+exists and has a size greater
-+than zero.
-+.It Fl t Ar file_descriptor
-+True if the file whose file descriptor number
-+is
-+.Ar file_descriptor
-+is open and is associated with a terminal.
-+.It Fl u Ar file
-+True if
-+.Ar file
-+exists and its set user ID flag
-+is set.
-+.It Fl w Ar file
-+True if
-+.Ar file
-+exists and is writable.
-+True
-+indicates only that the write flag is on.
-+The file is not writable on a read-only file
-+system even if this test indicates true.
-+.It Fl x Ar file
-+True if
-+.Ar file
-+exists and is executable.
-+True
-+indicates only that the execute flag is on.
-+If
-+.Ar file
-+is a directory, true indicates that
-+.Ar file
-+can be searched.
-+.It Fl z Ar string
-+True if the length of
-+.Ar string
-+is zero.
-+.It Fl L Ar file
-+True if
-+.Ar file
-+exists and is a symbolic link.
-+This operator is retained for compatibility with previous versions of
-+this program. Do not rely on its existence; use
-+.Fl h
-+instead.
-+.It Fl O Ar file
-+True if
-+.Ar file
-+exists and its owner matches the effective user id of this process.
-+.It Fl G Ar file
-+True if
-+.Ar file
-+exists and its group matches the effective group id of this process.
-+.It Fl S Ar file
-+True if
-+.Ar file
-+exists and is a socket.
-+.It Ar file1 Fl nt Ar file2
-+True if
-+.Ar file1
-+exists and is newer than
-+.Ar file2 .
-+.It Ar file1 Fl ot Ar file2
-+True if
-+.Ar file1
-+exists and is older than
-+.Ar file2 .
-+.It Ar file1 Fl ef Ar file2
-+True if
-+.Ar file1
-+and
-+.Ar file2
-+exist and refer to the same file.
-+.It Ar string
-+True if
-+.Ar string
-+is not the null
-+string.
-+.It Ar \&s\&1 Cm \&= Ar \&s\&2
-+True if the strings
-+.Ar \&s\&1
-+and
-+.Ar \&s\&2
-+are identical.
-+.It Ar \&s\&1 Cm \&!= Ar \&s\&2
-+True if the strings
-+.Ar \&s\&1
-+and
-+.Ar \&s\&2
-+are not identical.
-+.It Ar \&s\&1 Cm \&\*[Lt] Ar \&s\&2
-+True if string
-+.Ar \&s\&1
-+comes before
-+.Ar \&s\&2
-+based on the ASCII value of their characters.
-+.It Ar \&s\&1 Cm \&\*[Gt] Ar \&s\&2
-+True if string
-+.Ar \&s\&1
-+comes after
-+.Ar \&s\&2
-+based on the ASCII value of their characters.
-+.It Ar \&n\&1 Fl \&eq Ar \&n\&2
-+True if the integers
-+.Ar \&n\&1
-+and
-+.Ar \&n\&2
-+are algebraically
-+equal.
-+.It Ar \&n\&1 Fl \&ne Ar \&n\&2
-+True if the integers
-+.Ar \&n\&1
-+and
-+.Ar \&n\&2
-+are not
-+algebraically equal.
-+.It Ar \&n\&1 Fl \&gt Ar \&n\&2
-+True if the integer
-+.Ar \&n\&1
-+is algebraically
-+greater than the integer
-+.Ar \&n\&2 .
-+.It Ar \&n\&1 Fl \&ge Ar \&n\&2
-+True if the integer
-+.Ar \&n\&1
-+is algebraically
-+greater than or equal to the integer
-+.Ar \&n\&2 .
-+.It Ar \&n\&1 Fl \&lt Ar \&n\&2
-+True if the integer
-+.Ar \&n\&1
-+is algebraically less
-+than the integer
-+.Ar \&n\&2 .
-+.It Ar \&n\&1 Fl \&le Ar \&n\&2
-+True if the integer
-+.Ar \&n\&1
-+is algebraically less
-+than or equal to the integer
-+.Ar \&n\&2 .
-+.El
-+.Pp
-+These primaries can be combined with the following operators:
-+.Bl -tag -width Ar
-+.It Cm \&! Ar expression
-+True if
-+.Ar expression
-+is false.
-+.It Ar expression1 Fl a Ar expression2
-+True if both
-+.Ar expression1
-+and
-+.Ar expression2
-+are true.
-+.It Ar expression1 Fl o Ar expression2
-+True if either
-+.Ar expression1
-+or
-+.Ar expression2
-+are true.
-+.It Cm \&( Ns Ar expression Ns Cm \&)
-+True if expression is true.
-+.El
-+.Pp
-+The
-+.Fl a
-+operator has higher precedence than the
-+.Fl o
-+operator.
-+.Sh GRAMMAR AMBIGUITY
-+The
-+.Nm test
-+grammar is inherently ambiguous.  In order to assure a degree of consistency,
-+the cases described in
-+.St -p1003.2
-+section 4.62.4,
-+are evaluated consistently according to the rules specified in the
-+standards document.  All other cases are subject to the ambiguity in the
-+command semantics.
-+.Sh EXIT STATUS
-+The
-+.Nm test
-+utility exits with one of the following values:
-+.Bl -tag -width Ds
-+.It 0
-+expression evaluated to true.
-+.It 1
-+expression evaluated to false or expression was
-+missing.
-+.It \*[Gt]1
-+An error occurred.
-+.El
-+.Sh STANDARDS
-+The
-+.Nm test
-+utility implements a superset of the
-+.St -p1003.2
-+specification.

-+Description: The Debian Almquist Shell
-+ "dash" is a POSIX compliant shell that is much smaller than "bash".
-+ We take advantage of that by making it the shell on the installation
-+ root floppy, where space is at a premium.
-+ .
-+ It can be usefully installed as /bin/sh (because it executes scripts
-+ somewhat faster than "bash"), or as the default shell either of root
-+ or of a second user with a userid of 0 (because it depends on fewer
-+ libraries, and is therefore less likely to be affected by an upgrade
-+ problem or a disk failure).  It is also useful for checking that a
-+ script uses only POSIX syntax.
-+ .
-+ "bash" is a better shell for most users, since it has some nice
-+ features absent from "dash", and is a required part of the system.
