Fl f 48.Ar program ... 49.Sh DESCRIPTION 50The 51.Nm 52utility checks the standard binary, manual page, and source 53directories for the specified programs, printing out the paths of any 54it finds. The supplied names are first stripped of leading path name 55components, any single trailing extension added by 56.Xr gzip 1 57or 58.Xr compress 1 , 59and the leading 60.Ql s.\& 61or trailing 62.Ql ,v 63from a source code control system. 64.Pp 65The default path searched is the string returned by the 66.Xr sysctl 8 67utility for the 68.Dq user.cs_path 69string, with 70.Pa /usr/libexec 71and the current user's 72.Ev $PATH 73appended. Manual pages are searched by default along the 74.Ev $MANPATH . 75Program sources are located in a list of known standard places, 76including all the subdirectories of 77.Pa /usr/src 78and 79.Pa /usr/ports . 80.Pp 81The following options are available: 82.Bl -tag -width indent 83.It Fl B 84Specify directories to search for binaries. Requires the 85.Fl f 86option. 87.It Fl M 88Specify directories to search for manual pages. Requires the 89.Fl f 90option. 91.It Fl S 92Specify directories to search for program sources. Requires the 93.Fl f 94option. 95.It Fl b 96Search for binaries. 97.It Fl f 98Delimits the list of directories after the 99.Fl B , 100.Fl M , 101or 102.Fl S 103options, and indicates the beginning of the 104.Ar name 105list. 106.It Fl m 107Search for manual pages. 108.It Fl s 109Search for source directories. 110.It Fl u 111Search for 112.Dq unusual 113entries. A file is said to be unusual if it does not have one entry 114of each requested type. 115.El 116.Sh EXAMPLES 117The following finds all utilities under 118.Pa /usr/bin 119that do not have documentation: 120.Dl whereis -m -u /usr/bin/* 121.Sh SEE ALSO 122.Xr find 1 , 123.Xr locate 1 , 124.Xr man 1 , 125.Xr which 1 , 126.Xr sysctl 8 127.Sh BUGS 128The search for sources is implemented as a quick search as the 129first-level subdirectory of each element of the list of source 130directories first. If this didn't succeed, the utility 131.Xr locate 1 132is requested to do the search in deeper nested subdirectories. This 133might take some time, and will only succeed if the locate database is 134up-to-date. 135.Sh HISTORY 136The 137.Nm 138command appeared in 139.Bx 3.0 . 140This version re-implements the historical 141functionality that was lost in 142.Bx 4.4 . 143
