WhereIs History of Changes
--------------------------
v4.4a o WhereIs now has the ability to search for COM and
EXE files that have been compressed with PK-Ware's
new PKLite program. Since only .EXE and .COM files
will be "included" if you specify the "-PKLITE"
switch, you can greatly speed up the search time by
doing a command line like this:
WhereIs *.com *.exe -pklite
You can still do all commands on found files; so, for
example, you could un-pklite all PKLite'd files on
your drive with the following command:
WhereIs *.com -pklite -c"pklite -x &f"
v4.3a o Evidently, v4.2 of WhereIs brought out a bug in
the Turbo C++ v1.01 compiler. I had a lot of reports
from people about WhereIs "locking up" in strange
ways. One person told me he kept getting "Divide
by zero" errors, and WhereIs doesn't even HAVE a
division statement in it anywhere. Anyway, I
found one situation where I could lock up the
machine every time; when I compiled the exact code
under the old Turbo C 2.0 compiler, it worked just
fine. I barely have time to chase down my own bugs,
let alone Borland's <grin>, so I've went back to
Turbo C 2.0 with v4.3a. If anyone out there has
any more strange lockups happen, PLEASE let me know
(in as detailed a message as possible) what happenned
to you.
o Fixed a bug that was causing regular-expression
searches to not work when looking inside of ZOO
files.
o Added a new "-dir" switch that tells WhereIs to also
look at directory names when matching for filenames.
Any directories found will display as normal, except
the area where the filesize is normally shown will
display "<dir>" instead.
o Added a new '-gf' switch which tells WhereIs to
"go to the directory of the first found file
without prompting me".
o Added a new '&d' replaceable parameter for use
with the '-c' and '-o' command strings. This
will return the same thing as the '&p' (pathname)
parameter, but without the trailing '\' (unless
the path is the root directory).
o Per a user's request, added a new '-PL' switch
which changes the output display so that the path
name is on the left of the screen.
o In previous versions, if you did a "-o" or "-c"
command string on a matching file, WhereIs wouldn't
do some processing after that (such as verified
delete, goto directory, etc). WhereIs will now
perform any of these functions specified after
executing the specified "-c" or "-o" command.
v4.2b o Fixing the "-g" bug in v4.2a caused another bug that
caused the subdirectory change not to work.
v4.2a o Fixed a bug where the "-g" option would not work if
you tried to go to a root directory.
o Added a delete safety feature which now prompts you
to verify if you tell WhereIs to delete all files
on any drive. It seems that a lot of people (that,
I might add, haven't read the documentation) download
WhereIs and then promptly give it a command line like
this:
"whereis cde: *.bak -v -n"
and then watch while WhereIs starts deleting every
file on their hard drive. Seasoned WhereIs owners,
of course, know that the above command line actually
gets interpreted by WhereIs as:
"whereis cde:*.* *.bak -v -n".
o WhereIs will now correctly return ZIP member names
to the -c"command" feature when the ZIP directory
name includes a path. WhereIs still strips off the
pathname on the display screen, but will return the
full name when used with the &M parameter.
o WhereIs now opens archive files in "shared" mode.
Earlier versions opened these files exclusively,
which meant that you couldn't operate on archive
files with the -c"command" feature. Unfortunately,
PKZIP and PKARC are the only ones that will work
correctly; LHARC, ZOO, and ARC all open the file
looking for exclusive access, so you'll get a
"File share error" if you try to do something
like this:
whereis *.doc -ao -lzh -c"lharc x &f &m"
This will fail because WhereIs already has the file
open when it spawns off LHARC, and LHARC wants
exclusive control of the file.
v4.1a o Added the ability to execute a DOS command on any file
matches found.
o When you specify a "grep mask", WhereIs will now also
search inside of 4DOS's description files.
v4.0 o Added the ability to display only duplicate filename
entries.
o v4.0 marks the beginning of Shareware marketing.
o The program will no longer pause with the "More"
message if WhereIs detects that the output is being
redirected to a file or a printer.
v3.9-3.8 o These version numbers were skipped.
v3.7 o Sped up the grep searching slightly.
o ZIP searching now does a much better job of looking
for "corrupted" ZIP files.
v3.6 o Added the "-hidden" switch which informs WHEREIS to
include system and hidden files in the search.
o Added the optional WI_DRIVES environment variable to
hopefully alleviate some of the problems that occur
when WHEREIS is used on a Novell network.
v3.5 o Sped up ZIP searching by 50% due to a new method of
locating the "central directory".
o Sped up "grep" searching through archives by almost 70%.
o Added a '-z' switch, which only displays files that have
their "archive bit" set (ie: displays files modified
since your last backup was made).
v3.4 o Added grep-type searching on filenames.
o Added a '-U' switch to display all output in upper
case.
o Changed so that if you don't specify at least one
filespec on the command line, the default will be "*.*".
For example, in earlier versions you would have to say
"whereis *.* -s". Now you can just say "whereis -s".
v3.3-3.2 o Internal testing changes.
v3.1 o Fixed an obscure bug that would sometimes cause the
'date range' search to display files out of the range
if a file happened to fall on the last day of any month
that had 31 days in it. All date range checks are now
done with Greenwich Mean Time for added accuracy.
v3.0 o Changed the default display mode to put the filename on
the left of the screen.
o Added the ability to search specific ARC file formats.
o Added the '-AO' switch to search only archives.
o Added the '-F' to display filenames only.
o Changed the '-H' switch to start the search in the
current directory.
o Added the ability to exclude filenames with the
'-X' switch (up to 25 supported).
o Added the '-LT', '-EQ', and '-GT' switches for size
range searching.
o Added the '-S' and '-B' switches for date range
searching.
o Added the '-C' switch for searching only the PATH
directories.
o Changed the '-W' switch to get the true cluster size
for each drive searched. Earlier versions simply
assumed a cluster size of 2048 bytes.
v2.9 o Internal testing changes.
v2.8 o Added ZOO file searching.
v2.7 o Added LHARC file searching.
v2.6 o Internal testing changes.
v2.5
v2.4 o Added the "European-style" date display, per a user's
request.
o Added the '-W' switch to show wasted space.
o Added the '-H' switch to display filenames only.
o Added ZIP file searching.
v2.1-2.3 o Internal testing changes.
v2.0 o Changed to the three different display formats.
o Enhanced Control-C checking to allow aborting at any time.
This was not the case in prior versions if a user didn't
have BREAK=ON specified in their AUTOEXEC.BAT file.
o Changed the '-G' switch to prompt the user before going
to the found subdirectory.
v1.9 o Filenames are now searched for first in the current
directory instead of searching for subdirectories first.
v1.8 o Added the ability to specify multiple drives and filespecs
on the command line (ie: whereis cde:*.dat d:test.prg).
o Added the '-D' switch to search all drives.
o Added the '-E' switch to allow "*.*" use for directory
searches.
o Added the '-G' switch for "goto found subdirectory".
o Added the '-P' switch for page breaking.
o Added the '-V' switch for file deletion.
o Added support for the WHEREIS environment variable.
o Added the '-I' switch to ignore the environment variable.
v1.7-1.1 o Internal testing changes.
v1.0 o Initial release.
