whereis - locate the binary, source, and manual page files for a command
/usr/ucb/whereis [ -bmsu ] [ -BMS directory... -f ] filename...
SUNWscpu
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 .ext, for example,
.c. Prefixes of s. resulting from use of source code control are also dealt
with. whereis then attempts to locate the desired program in a list of standard
places:
- -b
- Search only for binaries.
- -m
- Search only for manual sections.
- -s
- Search only
for sources.
- -u
- Search for unusual entries. A file is said to be unusual if
it does not have one entry of each requested type. Thus ‘whereis -m -u *’ asks
for those files in the current directory which have no documentation.
- -B
- Change or otherwise limit the places where whereis searches for binaries.
- -M
- Change or otherwise limit the places where whereis searches for manual
sections.
- -S
- Change or otherwise limit the places where whereis searches
for sources.
- -f
- Terminate the last directory list and signals the start of
file names, and must be used when any of the -B, -M, or -S options are used.
Find all files in /usr/bin which are not documented in /usr/share/man/man1
with source in /usr/src/cmd:
example% cd /usr/ucb
example% whereis -u -M /usr/share/man/man1 -S /usr/src/cmd -f *
- /usr/src/*
- /usr/{doc,man}/*
- /etc, /usr/{lib,bin,ucb,old,new,local}
-
chdir(2)
Since whereis uses chdir(2)
to run faster, pathnames given with the
-M, -S, or -B must be full; that is, they must begin with a ‘/’.
