69: .Sh DESCRIPTION
70: The file(s) are moved (or copied if the
71: .Fl c
72: option is specified) to the target file or directory.
73: If the destination is a directory, then the
74: .Ar file
75: is moved into
76: .Ar directory
77: with its original filename.
1.9 aaron 78: If the target file already exists, it is
1.8 millert 79: either renamed to
80: .Ar file.old
1.9 aaron 81: if the
1.8 millert 82: .Fl b
83: option is given
84: or overwritten
85: if permissions allow, An alternate backup suffix may be specified via the
86: .Fl B
87: option's argument.
88: .Pp
1.10 ! aaron 89: The options are as follows:
1.1 deraadt 90: .Bl -tag -width Ds
1.8 millert 91: .It Fl b
92: Backup any existing files before overwriting them by renaming
1.9 aaron 93: them to
1.8 millert 94: .Ar file.old . See
95: .Fl B
96: for specifying a different backup suffix.
97: .It Fl B Ar suffix
1.9 aaron 98: Use
1.8 millert 99: .Ar suffix
1.9 aaron 100: as the backup suffix if
1.8 millert 101: .Fl b
102: is given.
1.3 millert 103: .It Fl C
104: Copy the file.
105: If the target file already exists and the files are the same,
106: then don't change the modification time of the target.
1.1 deraadt 107: .It Fl c
1.3 millert 108: Copy the file. This is actually the default. The
109: .Fl c
110: option is only included for backwards compatibility.
111: .It Fl d
1.9 aaron 112: Create directories.
1.3 millert 113: Missing parent directories are created as required.
1.1 deraadt 114: .It Fl f
115: Specify the target's file flags.
116: (See
117: .Xr chflags 1
118: for a list of possible flags and their meanings.)
119: .It Fl g
1.3 millert 120: Specify a group. A numeric GID is allowed.
1.1 deraadt 121: .It Fl m
122: Specify an alternate mode.
123: The default mode is set to rwxr-xr-x (0755).
124: The specified mode may be either an octal or symbolic value; see
125: .Xr chmod 1
126: for a description of possible mode values.
127: .It Fl o
1.3 millert 128: Specify an owner. A numeric UID is allowed.
129: .It Fl p

1.3 millert 134: except if the target file doesn't already exist or is different,
135: then preserve the modification time of the file.
136: .It Fl S
137: Safe copy. Normally,
138: .Nm install
139: unlinks an existing target before installing the new file. With the
140: .Fl S
141: flag a temporary file is used and then renamed to be
142: the target. The reason this is safer is that if the copy or
143: rename fails, the existing target is left untouched.
1.1 deraadt 144: .It Fl s
1.6 aaron 145: .Nm install
1.1 deraadt 146: exec's the command
1.5 millert 147: .Pa /usr/bin/strip
1.1 deraadt 148: to strip binaries so that install can be portable over a large
1.5 millert 149: number of systems and binary types. If the environment variable
150: .Ev STRIP
