SCRIPT(1) UNIX Programmer's Manual SCRIPT(1) NAME script - make typescript of terminal session SYNOPSIS script [ -a ] [ -q ] [ -S shell ] [ file ] DESCRIPTION _S_c_r_i_p_t makes a typescript of everything printed on your ter- minal. The typescript is saved in a file, and can be sent to the line printer later with _l_p_r. If a file name is given, the typescript is saved there. If not, the typescript is saved in the file _t_y_p_e_s_c_r_i_p_t. To exit script, type control D. This sends an end of file to all processes you have started up, and causes script to exit. For this reason, control D behaves as though you had typed an infinite number of control D's. This program is useful when using a crt and a hard-copy record of the dialog is desired, as for a student handing in a program that was developed on a crt when hard-copy termi- nals are in short supply. -S lets you specify the shell to use. The default depends on the system: If the variable SHELL is set in the environ- ment, it is used if possible. The -q flag asks for ``quiet mode'', where the ``script started'' and ``script done'' messages are turned off. The -a flag causes script to append to the typescript file instead of creating a new file. AUTHOR Mark Horton BUGS Since UNIX has no way to write an end-of-file down a pipe without closing the pipe, there is no way to simulate a sin- gle control D without ending script. The new shell has its standard input coming from a pipe rather than a tty, so stty will not work, and neither will ttyname. In particular, this means that screen editors such as _v_i(1) and the job control facilities of _c_s_h(1) are ino- perative. When the user interrupts a printing process, _s_c_r_i_p_t attempts to flush the output backed up in the pipe for better response. Usually the next prompt also gets flushed. Printed 11/10/80 1
