Regular files 52named "md5", or which have an ".md5" or an ".inf" extension, are 53assumed to be of the implied type, otherwise format is determined from 54content. If a directory is specified, it is searched for 55appropriately-named files only. 56.Pp 57Options are as follows: 58.Bl -tag -width 8n -offset indent 59.It Fl a 60Report on all distribution components, not just those in respect of 61which errors are detected. 62.It Fl i 63Ignore missing distribution components. 64.It Fl r 65Search specified directories recursively. 66.It Fl s 67Suppress complaints about inaccessible checksum files and directories. 68.It Fl x 69Verify the existence of distribution components (and also check sizes, 70in the case of .inf files), but omit the more time-consuming step of 71actually computing and comparing checksums. 72.It Fl d Ar dir 73Look for distribution components in the directory 74.Ar dir . 75.It Fl n Ar name 76Access distribution components using the filename 77.Ar name . 78When accessing .inf file components, append the appropriate 79extension to the filename. 80.It Fl t Ar type 81Assume that all specified checksum files are of the format 82.Ar type , 83and search directories only for files in this format (where 84.Ar type 85is either "md5" or "inf"). 86.El 87.Sh EXIT STATUS 88Exit status is 0 if no errors were detected, 1 if errors were found in 89a distribution, and 2 if usage errors, inaccessible input files, or 90other system errors were encountered. 91.Sh SEE ALSO 92.Xr cksum 1 , 93.Xr md5 1 94.Sh NOTES 95Both 96.Bx 97and 98.Tn DOS 99versions of 100.Nm 101are available. 102
