A value of 0 85causes 86.Nm 87to flush for every character I/O event. The default interval is 8830 seconds. 89.El 90.Pp 91The script ends when the forked shell (or command) exits (a 92.Em control-D 93to exit 94the Bourne shell 95.Pf ( Xr sh 1 ) , 96and 97.Em exit , 98.Em logout 99or 100.Em control-D 101(if 102.Em ignoreeof 103is not set) for the 104C-shell, 105.Xr csh 1 ) . 106.Pp 107Certain interactive commands, such as 108.Xr vi 1 , 109create garbage in the typescript file. 110The 111.Nm 112utility works best with commands that do not manipulate the screen. 113The results are meant to emulate a hardcopy terminal, not an addressable one. 114.Sh ENVIRONMENT 115The following environment variable is utilized by 116.Nm : 117.Bl -tag -width SHELL 118.It Ev SHELL 119If the variable 120.Ev SHELL 121exists, the shell forked by 122.Nm 123will be that shell. 124If 125.Ev SHELL 126is not set, the Bourne shell 127is assumed. 128(Most shells set this variable automatically). 129.El 130.Sh SEE ALSO 131.Xr csh 1 132(for the 133.Em history 134mechanism). 135.Sh HISTORY 136The 137.Nm 138command appeared in 139.Bx 3.0 . 140.Sh BUGS 141The 142.Nm 143utility places 144.Sy everything 145in the log file, including linefeeds and backspaces. 146This is not what the naive user expects. 147.Pp 148It is not possible to specify a command without also naming the script file 149because of argument parsing compatibility issues. 150.Pp 151When running in 152.Fl k 153mode, echo cancelling is far from ideal. The slave terminal mode is checked 154for ECHO mode to check when to avoid manual echo logging. This does not 155work when in a raw mode where the program being run is doing manual echo. 156
