If the user's home directory is owned 98by the user, 99.Nm 100asks whether you wish to remove the user's home directory and everything 101below. 102.Pp 103As 104.Nm 105operates, it informs the user regarding the current activity. If any 106errors occur, they are posted to standard error and, if it is possible for 107.Nm 108to continue, it will. 109.Pp 110Available options: 111.Pp 112.Bl -tag -width username 113.It Fl y 114Affirm - any question that would be asked is answered implicitly in 115the affirmative (i.e., yes). A username must also be specified on the 116command line if this option is used. 117.It Ar \&username 118Identifies the user to be removed; if not present, 119.Nm 120interactively asks for the user to be removed. 121.El 122.Sh FILES 123.Bl -tag -width /etc/master.passwd -compact 124.It Pa /etc/master.passwd 125.It Pa /etc/passwd 126.It Pa /etc/group 127.It Pa /etc/spwd.db 128.It Pa /etc/pwd.db 129.El 130.Sh SEE ALSO 131.Xr at 1 , 132.Xr chpass 1 , 133.Xr crontab 1 , 134.Xr finger 1 , 135.Xr passwd 1 , 136.Xr group 5 , 137.Xr passwd 5 , 138.Xr adduser 8 , 139.Xr pw 8 , 140.Xr pwd_mkdb 8 , 141.Xr vipw 8 142.Sh HISTORY 143The 144.Nm 145utility appeared in 146.Fx 2.2 . 147.Sh BUGS 148The 149.Nm 150utility does not comprehensively search the file system for all files 151owned by the removed user and remove them; to do so on a system 152of any size is prohibitively slow and I/O intensive. 153It is also unable to remove symbolic links that were created by the 154user in 155.Pa /tmp 156or 157.Pa /var/tmp , 158as symbolic links on 159.Bx 4.4 160file systems do not contain information 161as to who created them. 162Also, there may be other files created in 163.Pa /var/mail 164other than 165.Pa /var/mail/ Ns Ar username 166and 167.Pa /var/mail/.pop. Ns Ar username 168that are not owned by the removed user but should be removed. 169.Pp 170The 171.Nm 172utility has no knowledge of YP/NIS, and it operates only on the 173local password file. 174
