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.

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.
