SHTOOL-SLO.TMP(1)					      GNU Portable Shell Tool						 SHTOOL-SLO.TMP(1)

NAME

       shtool-slo - GNU shtool separate linker options by library class

SYNOPSIS

       shtool slo [-p|--prefix str] -- -Ldir -llib [-Ldir -llib ...]

DESCRIPTION

       This command separates the linker options ``-L'' and ``-l'' by library class. It's argument line can actually be an arbitrary command line
       where those options are contained. slo parses these two options only and ignores the remaining contents. The result is a trivial shell
       script on "stdout" which defines six variables containing the ``-L'' and ``-l'' options sorted by class:

       ``"SLO_DIRS_OBJ"'' and ``"SLO_LIBS_OBJ"'' contains the ``-L'' and ``-l'' options of static libraries,  ``"SLO_DIRS_PIC"'' and
       ``"SLO_LIBS_PIC"'' contains the ``-L'' and ``-l'' options of static libraries containing PIC ("Position Independent Code") and
       ``"SLO_DIRS_DSO"'' and ``"SLO_LIBS_DSO"'' contains the ``-L'' and ``-l'' options of shared libraries. The -p option can be used to change
       the default variable prefix from ""SLO_"" to str.

       The intent of this separation is to provide a way between static and shared libraries which is important if one wants to link custom DSOs
       against libraries, because not all platforms all one to link these DSOs against shared libraries. So one first has to separate out the
       shared libraries and link the DSO only against the static libraries.  One can use this command also to just sort the options.

OPTIONS

       The following command line options are available.

       -p, --prefix str
	       FIXME

       -Ldir
	   Directory where libraries are searched in.

       -llib
	   Library to search for.

EXAMPLE

	#   configure.in
	LINK_STD="$LDFLAGS $LIBS"
	eval `shtool slo $LINK_STD`
	LINK_DSO="$SLO_DIRS_OBJ $SLO_LIBS_OBJ $SLO_DIRS_PIC $SLO_LIBS_PIC"
	  :

HISTORY

       The GNU shtool slo command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1998 for Apache.  It was later taken
       over into GNU shtool.

NAME

       shtool-echo - GNU shtool echo(1) extensional command

SYNOPSIS

       shtool echo [-n|--newline] [-e|--expand] string

DESCRIPTION

       shtool echo is an echo(1) style command which prints string to stdout and optionally provides special expansion constructs (terminal bold
       mode, environment details, date, etc) and newline control. The trick of this command is that it provides a portable -n option and hides the
       gory details needed to find out the environment details under option -e.

OPTIONS

       The following command line options are available.

       -n, --newline
	   By default, output is written to stdout followed by a "newline" (ASCII character 0x0a). If option -n is used, this newline character is
	   omitted.

       -e, --expand
	   If option -e is used, string can contain special "%x" constructs which are expanded before the output is written. Currently the
	   following constructs are recognized:

	   %B  switch terminal mode to bold display mode.

	   %b  switch terminal mode back to normal display mode.

	   %u  the current user name.

	   %U  the current user id (numerical).

	   %g  the current group name.

	   %G  the current group id (numerical).

	   %h  the current hostname (without any domain extension).

	   %d  the current domain name.

	   %D  the current day of the month.

	   %M  the current month (numerical).

	   %m  the current month name.

	   %Y  the current year.

EXAMPLE

	#   shell script
	shtool echo -n -e "Enter your name [%B%u%b]: "; read name
	shtool echo -e "Your Email address might be %u@%h%d"
	shtool echo -e "The current date is %D-%m-%Y"

HISTORY

       The GNU shtool echo command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1998 for Website META Language (WML)
       under the name buildinfo. It was later taken over into GNU shtool.
