Xcoffdate is something I whipped up quickly to solve several problems:
X
X 1) dates on executable files being altered by "install" scripts
X 2) verifying which of several *.o files was, in fact, most recent
X
XFrom the program's docs:
X
Xdisplays the date embedded in COFF files and optionally alters the
Xfiles' access and modify dates to be that of their COFF f_timdat.
X
Xusage: coffdate [ -a ] [ -m ] [ - { c | s } ] filelist
X
Xwhere: -a resets file's access date&time to the COFF f_timdat
X -m resets file's modify date&time to the COFF f_timdat
X -c list only COFF files (i.e. suppress "not a COFF file")
X -s silent operation
X
Xoptions may be combined noting that -c and -s are mutually exclusive.
X
XThis version is for mc68k COFF files; to function with other systems'
XCOFF files the equates in chkCOFF() need to be changed to reflect those
Xin /usr/include/sgs.h or /usr/include/filehdr.h on those other systems.
