whereis v1.1 (Gno)
|
||||
|
||||
============
|
||||
INSTALLATION
|
||||
============
|
||||
|
||||
If you have Gno and dmake, type "dmake install". Otherwise:
|
||||
|
||||
FILE: COPY TO:
|
||||
|
||||
Gno: Orca/whereis 17/whereis [if desired]
|
||||
Gno/whereis /usr/bin/whereis
|
||||
whereis.1 $(USRMAN)/man1/whereis.1
|
||||
|
||||
Orca: Orca/whereis 17/whereis
|
||||
whereis.cat 17/help/whereis
|
||||
|
||||
=====
|
||||
NOTES
|
||||
=====
|
||||
|
||||
Whereis is VERY dependant on pathnames.
|
||||
|
||||
This archive consist of both Orca shell and Gno versions. Both versions
|
||||
will work with both shells, the difference being that in the Gno version
|
||||
the leading "31" has been stripped from pathnames. (It is no longer needed
|
||||
because of namespace.)
|
||||
|
||||
I strongly recommend _not_ using the Gno version with the Orca shell unless
|
||||
you have actual partitions named "/usr", "/bin", "/etc", and so on, as you
|
||||
will get _many_ accesses to all online devices in this case.
|
||||
|
||||
A -V flag and rVersion resource have been added to show version information.
|
||||
|
||||
A -c flag has been added to provide case-insensitive searches.
|
||||
|
||||
The source is released because it is small, and you can change the pathnames
|
||||
if you wish.

|
||||
HISTORY
|
||||
=======
|
||||
|
||||
v1.1: Rewritten to take advantage of Gno 2.x's namespace feature.
|
||||
Separate Gno and Orca versions created.
|
||||
Prototyped.
|
||||
Disabled references to the /man volume (both versions).
|
||||
Fixed up man page.
|
||||
Added -V flag to show version information.
|
||||
Added -c flag to force case-insensitive searches.
|
||||
Added "17" to list of directories to search for binaries.
|
||||
Added "17/help" to list of directories to search for man pages.
|
||||
|
||||
v1.0: Initial release.

.SH DESCRIPTION
|
||||
.B whereis
|
||||
locates source/binary and manuals sections for specified
|
||||
files.
|
||||
The supplied names are first stripped of leading pathname components
|
||||
and any (single) trailing extension of the form
|
||||
.BR .ext ,
|
||||
for example,
|
||||
.BR .c .
|
||||
Prefixes of
|
||||
.B s.
|
||||
resulting from use of source code control are also dealt with.
|
||||
.B whereis
|
||||
then attempts to locate the desired program in
|
||||
a list of standard places:

not have one entry of each requested type. Therefore
