| 22 | .SH DESCRIPTION | |
| 23 | .I Whereis | |
| 24 | locates source/binary and manuals sections for specified files. | |
| 25 | The supplied names are first stripped of leading pathname components | |
| 26 | and any (single) trailing extension of the form ``.ext'', e.g. ``.c''. | |
| 27 | Prefixes of ``s.'' resulting from use of source code control are also | |
| 28 | dealt with. | |
| 29 | .I Whereis | |
| 30 | then attempts to locate the desired program in a list of standard places. | |
| 31 | If any of the | |
| 32 | .B \-b, | |
| 33 | .B \-s | |
| 34 | or | |
| 35 | .B \-m | |
| 36 | flags are given then | |
| 37 | .I whereis | |
| 38 | searches only for binaries, sources or manual sections respectively | |
| 39 | (or any two thereof). | |
| 40 | The | |
| 41 | .B \-u | |
| 42 | flag may be used to search for unusual entries. | |
| 43 | A file is said to be unusual if it does not have one entry of | |
| 44 | each requested type. | |
| 45 | Thus ``whereis -m -u *'' asks for those files in the current | |
| 46 | directory which have no documentation. | |
| 47 | .sp | |
| 48 | Finally, the | |
| 49 | .B \-B | |
| 50 | .B \-M | |
| 51 | and | |
| 52 | .B \-S | |
| 53 | flags may be used to change or otherwise limit the places where | |
| 54 | .I whereis | |
| 55 | searches. | |
| 56 | The | |
| 57 | .B \-f | |
| 58 | file flags is used to terminate the last such directory list | |
| 59 | and signal the start of file names. | |
| 60 | .SH EXAMPLE | |
| 61 | The following finds all the files in /usr/bin which are not documented | |
| 62 | in /usr/man/man1 with source in /usr/src/cmd: | |
| 63 | .IP | |
| 64 | cd /usr/ucb | |
| 65 | .br | |
| 66 | whereis \-u \-M /usr/man/man1 \-S /usr/src/cmd \-f * | |
| 67 | .SH FILES | |
| 68 | /usr/src/* | |
| 69 | .br | |
| 70 | /usr/{doc,man}/* | |
| 71 | .br | |
| 72 | /lib, /etc, /usr/{lib,bin,ucb,old,new,local} | |

73 | .SH BUGS |
| 74 | Since the program uses | |
| 75 | .IR chdir (2) | |
| 76 | to run faster, pathnames given with the | |
| 77 | .B \-M | |
| 78 | .B \-S | |
| 79 | and | |
| 80 | .B \-B | |
| 81 | must be full; i.e. they must begin with a ``/''. |
