|
# Make checksum files for files in ``tardir''. Usage:
|
|
# makesums [-a] [-t tardir] [setname [...]]
|
|
#
|
|
# If -t is omitted, RELEASEDIR must be set and not empty.
|
|
# The ``setname'' arguments comprise a list of files to checksum,
|
|
# and may be omitted (in which case ``*.tgz'' is used).
|
|
# If -a is given, then the list of sets is ignored, and ``*'' is used.
|
|
#
|
|
# After shell glob expansion, the list of sets is filtered to remove known
|
|
# output file names (of the form *SUM and MD5), non-existent files, and
|
|
# subdirectories. If this filtering leaves no files, then no output files are
|
|
# produced. Otherwise the resulting list of files are checksummed and four
|
|
# output files (BSDSUM, CKSUM, MD5, SYSVSUM) are produced.
