Notes on command line arguments:
Mode - must be the first character of the first argument. Leading '-'
is ignored:
e/x - Extract
l/v - List (normal / verbose mode)
t - Test CRC
p - Print files to STDOUT
Options - flags following the mode character. Options are accepted
even if they are inappropriate for the mode, eg. "lha lf".
q[level] - Quiet mode. Normal running is quiet level 0.
in list mode, quiet level 2 strips header/footer from
listing.
in extract mode, overwrite is always performed, and:
- at quiet level 1, the 'progress bar' is not shown.
- at quiet level 2, no messages are printed at all.
in test mode, behavior is similar to extract mode, but
level 2 behavior is similar to level 0.
in print mode, at quiet level 2 the filename is not
printed before the file contents.
all quiet modes imply 'f', disabling overwrite without
confirmation.
f - Force overwrite. When extracting, existing files are
overwritten with no confirmation.
n - Don't execute commands, just do a dry run of what would
be done.
eg. for lha en:
EXTRACT lhasa/src/ (directory)
EXTRACT lhasa/src/extract.c
EXTRACT lhasa/src/extract.c but file is exist.
eg. for lha tn:
VERIFY lhasa/src/main.c
i - Ignore directory path. When extracting, the directory
of each file is ignored - they are all extracted into
the same directory.
Also applies to test mode - the output filename of the
tested file does not include the directory.
In print mode, the path is not printed in the header
before each file.
v - Verbose mode, prints extra information.
in list mode, verbose mode splits the filename onto a
separate preceding line and the header level is shown
in its normal place.
in extract mode, verbose mode prints a message when
creating a directory. If creating missing parent directories,
they are printed in reverse order, eg.
Making directory "lhasa/src".
Making directory "lhasa".
lhasa/src/main.c - Melted : o
w=dir - Specify destination directory to extract files. Must be
the last option specified. '=' can be omitted. If combined
with 'i', all files get placed in that one directory.
