40: .Sh NAME
41: .Nm script
42: .Nd make typescript of terminal session
43: .Sh SYNOPSIS
44: .Nm script
45: .Op Fl a
46: .Op Ar file
47: .Sh DESCRIPTION
48: .Nm Script
49: makes a typescript of everything printed on your terminal.
50: It is useful for students who need a hardcopy record of an interactive
51: session as proof of an assignment, as the typescript file
52: can be printed out later with
53: .Xr lpr 1 .
54: .Pp
55: If the argument
56: .Ar file
57: is given,
58: .Nm
59: saves all dialogue in
60: .Ar file .
61: If no file name is given, the typescript is saved in the file
62: .Pa typescript .
63: .Pp
64: Option:
65: .Bl -tag -width Ds
66: .It Fl a
67: Append the output to
68: .Ar file
69: or
70: .Pa typescript ,
71: retaining the prior contents.
72: .El
73: .Pp
74: The script ends when the forked shell exits (a
75: .Em control-D
76: to exit
77: the Bourne shell
78: .Pf ( Xr sh 1 ) ,
79: and
80: .Em exit ,
81: .Em logout
82: or
83: .Em control-d
84: (if
85: .Em ignoreeof
86: is not set) for the
87: C-shell,
88: .Xr csh 1 ) .
89: .Pp
90: Certain interactive commands, such as
91: .Xr vi 1 ,
92: create garbage in the typescript file.
93: .Nm Script
94: works best with commands that do not manipulate the
95: screen, the results are meant to emulate a hardcopy
96: terminal.
97: .Sh ENVIRONMENT
98: The following environment variable is utilized by
99: .Nm script :
100: .Bl -tag -width SHELL
101: .It Ev SHELL
102: If the variable
103: .Ev SHELL
104: exists, the shell forked by
105: .Nm script
106: will be that shell. If
107: .Ev SHELL
108: is not set, the Bourne shell
109: is assumed. (Most shells set this variable automatically).
110: .El
111: .Sh SEE ALSO
112: .Xr csh 1
113: (for the
114: .Em history
115: mechanism).

118: .Nm script
119: command appeared in
120: .Bx 3.0 .
121: .Sh BUGS
