md(1) BSD General Commands Manual md(1)
NAME
md -- process raw dependency files produced by cpp -MD
SYNOPSIS
md [-d] [-f] [-m makefile] [-u makefile] [-o outputfile] [-v] [-x] [-D c|d|m|o|t|D]
DESCRIPTION
The md command basically does two things:
Process the raw dependency files produced by the cpp -MD option. There is one line in the file for every #include encountered, but there are
repeats and patterns like .../dir1/../dir2 that appear which should reduce to .../dir2. md canonicalizes and flushes repeats from the depen-
dency list. It also sorts the file names and "fills" them to a 78 character line.
md also updates the makefile directly with the dependency information, so the .d file can be thrown away (see d option). This is done to
save space. md assumes that dependency information in the makefile is sorted by .o file name and it procedes to merge in (add/or replace [as
appropriate]) the new dependency lines that it has generated. For time effeciency, md assumes that any .d files it is given that were cre-
ated before the creation date of the "makefile" were processed already. It ignores them unless the force flag [f] is given.
FLAG SUMMARY
-d delete the .d file after it is processed
-f force an update of the dependencies in the makefile even though the makefile is more recent than the .n file (This implies that md has
been run already.)
-m makefile specify the makefile to be upgraded. The defaults are makefile and then Makefile
-u makefile like -m above, but the file will be created if necessary
-o outputfile specify an output file for the dependencies other than a makefile
-v set the verbose flag
-x expunge old dependency info from makefile
-D c|d|m|o|t|D subswitch for debugging. can be followed by any of "c", "d", "m", "o", "t", "D" meaning:
c show file contents
d show new dependency crunching
m show generation of makefile
o show files being opened
t show time comparisons
D show very low level debugging

BUGS
Old, possibly not used by anyone.
HISTORY
The md utility was written by Robert V Baron at Carnegie-Mellon University.
