A value of 0 87causes 88.Nm 89to flush for every character I/O event. The default interval is 9030 seconds. 91.El 92.Pp 93The script ends when the forked shell (or command) exits (a 94.Em control-D 95to exit 96the Bourne shell 97.Pf ( Xr sh 1 ) , 98and 99.Em exit , 100.Em logout 101or 102.Em control-d 103(if 104.Em ignoreeof 105is not set) for the 106C-shell, 107.Xr csh 1 ) . 108.Pp 109Certain interactive commands, such as 110.Xr vi 1 , 111create garbage in the typescript file. 112The 113.Nm 114utility works best with commands that do not manipulate the screen. 115The results are meant to emulate a hardcopy terminal, not an addressable one. 116.Sh ENVIRONMENT 117The following environment variable is utilized by 118.Nm : 119.Bl -tag -width SHELL 120.It Ev SHELL 121If the variable 122.Ev SHELL 123exists, the shell forked by 124.Nm 125will be that shell. 126If 127.Ev SHELL 128is not set, the Bourne shell 129is assumed. 130(Most shells set this variable automatically). 131.El 132.Sh SEE ALSO 133.Xr csh 1 134(for the 135.Em history 136mechanism). 137.Sh HISTORY 138The 139.Nm 140command appeared in 141.Bx 3.0 . 142.Sh BUGS 143The 144.Nm 145utility places 146.Sy everything 147in the log file, including linefeeds and backspaces. 148This is not what the naive user expects. 149.Pp 150It is not possible to specify a command without also naming the script file 151because of argument parsing compatibility issues. 152.Pp 153When running in 154.Fl k 155mode, echo cancelling is far from ideal. The slave terminal mode is checked 156for ECHO mode to check when to avoid manual echo logging. This does not 157work when in a raw mode where the program being run is doing manual echo. 158
