39 .Nd make typescript of terminal session
50 makes a typescript of everything printed on your terminal.
51 It is useful for students who need a hardcopy record of an interactive
52 session as proof of an assignment, as the typescript file
53 can be printed out later with
62 If no file name is given, the typescript is saved in the file
72 retaining the prior contents.
74 Run the COMMAND rather than an interactive shell.
75 This makes it easy for a script to capture the output of a program that
76 behaves differently when its stdout is not a tty.
78 Flush output after each write. This is nice for telecooperation:
79 One person does `mkfifo foo; script -f foo' and another can
80 supervise real-time what is being done using `cat foo'.
84 Output timing data to standard error. This data contains two fields,
85 separated by a space. The first field indicates how much time elapsed since
86 the previous output. The second field indicates how many characters were
87 output this time. This information can be used to replay typescripts with
88 realistic typing and output delays.
91 The script ends when the forked shell exits (a
107 Certain interactive commands, such as
109 create garbage in the typescript file.
111 works best with commands that do not manipulate the

143 in the log file, including linefeeds and backspaces.
144 This is not what the naive user expects.
