NAME
tsort - topological sort SYNOPSIS
/usr/ccs/bin/tsort [file] DESCRIPTION
The tsort command produces on the standard output a totally ordered list of items consistent with a partial ordering of items mentioned in the input file. The input consists of pairs of items (nonempty strings) separated by blanks. Pairs of different items indicate ordering. Pairs of identical items indicate presence, but not ordering. OPERANDS
The following operand is supported: file A path name of a text file to order. If no file operand is given, the standard input is used. EXAMPLES
Example 1: An example of the tsort command The command: example% tsort <<EOF a b c c d e g g f g e f EOF produces the output: a b c d e f g ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of tsort: LANG, LC_ALL, LC_CTYPE, LC_MES- SAGES, and NLSPATH. EXIT STATUS
The following exit values are returned: 0 Successful completion. >0 An error occurred. ATTRIBUTES

NAME
lorder - find ordering relation for an object or library archive SYNOPSIS
lorder filename... DESCRIPTION
The input is one or more object or library archive filenames (see ar(1)). The standard output is a list of pairs of object file or archive member names; the first file of the pair refers to external identifiers defined in the second. The output may be processed by tsort(1) to find an ordering of a library suitable for one-pass access by ld. Note that the link editor ld is capable of multiple passes over an ar- chive in the portable archive format (see ar.h(3HEAD)) and does not require that lorder be used when building an archive. The usage of the lorder command may, however, allow for a more efficient access of the archive during the link edit process. The following example builds a new library from existing .o files. ar -cr library `lorder *.o | tsort` FILES
TMPDIR/*symref temporary files TMPDIR/*symdef temporary files TMPDIR usually /var/tmp but can be redefined by setting the environment variable TMPDIR (see tempnam() in tmpnam(3C)) ATTRIBUTES

lorder will accept as input any object or archive file, regardless of its suffix, provided there is more than one input file. If there is but a single input file, its suffix must be .o. The length of the filename for TMPDIR is limited to whatever sed allows. SunOS 5.11 29 Oct 1991 lorder(1)
