ðððð
     ðð°ð¿ð¶ð½ð â make typescript of terminal session

ðððððððð
     ðð°ð¿ð¶ð½ð [-ð®ð±ð²ð³ð¸ð½ð¾ð¿] [-ð pÌ²iÌ²pÌ²eÌ²] [-ð tÌ²iÌ²mÌ²eÌ²] [fÌ²iÌ²lÌ²eÌ² [cÌ²oÌ²mÌ²mÌ²aÌ²nÌ²dÌ² .Ì².Ì².Ì²]]

ððððððððððð
     The ðð°ð¿ð¶ð½ð utility makes a typescript of everything printed on your termiâ
     nal.  It is useful for students who need a hardcopy record of an interacâ
     tive session as proof of an assignment, as the typescript file can be
     printed out later with lpr(1).

     If the argument fÌ²iÌ²lÌ²eÌ² is given, ðð°ð¿ð¶ð½ð saves all dialogue in fÌ²iÌ²lÌ²eÌ².  If no
     file name is given, the typescript is saved in the file tÌ²yÌ²pÌ²eÌ²sÌ²cÌ²rÌ²iÌ²pÌ²tÌ².

     If the argument cÌ²oÌ²mÌ²mÌ²aÌ²nÌ²dÌ² is given, ðð°ð¿ð¶ð½ð will run the specified command
     with an optional argument vector instead of an interactive shell.

     The following options are available:

     -ð®      Append the output to fÌ²iÌ²lÌ²eÌ² or tÌ²yÌ²pÌ²eÌ²sÌ²cÌ²rÌ²iÌ²pÌ²tÌ², retaining the prior conâ
             tents.

     -ð±      When playing back a session with the -ð½ flag, do not sleep between
             records when playing back a timestamped session.

     -ð²      Accepted for compatibility with uÌ²tÌ²iÌ²lÌ²-Ì²lÌ²iÌ²nÌ²uÌ²xÌ² ðð°ð¿ð¶ð½ð.  The child comâ
             mand exit status is always the exit status of ðð°ð¿ð¶ð½ð.

     -ð pÌ²iÌ²pÌ²eÌ²
             Immediately flush output after each write.  This will allow a user
             to create a named pipe using mkfifo(1) and another user may watch
             the live session using a utility like cat(1).

     -ð¸      Log keys sent to the program as well as output.

     -ð½      Play back a session recorded with the -ð¿ flag in real time.

     -ð¾      Run in quiet mode, omit the start, stop and command status mesâ
             sages.

     -ð¿      Record a session with input, output, and timestamping.

     -ð tÌ²iÌ²mÌ²eÌ²
             Specify the interval at which the script output file will be
             flushed to disk, in seconds.  A value of 0 causes ðð°ð¿ð¶ð½ð to flush
             after every character I/O event.  The default interval is 30 secâ
             onds.

     The script ends when the forked shell (or command) exits (a cÌ²oÌ²nÌ²tÌ²rÌ²oÌ²lÌ²-Ì²DÌ² to
     exit the Bourne shell (sh(1)), and eÌ²xÌ²iÌ²tÌ², lÌ²oÌ²gÌ²oÌ²uÌ²tÌ² or cÌ²oÌ²nÌ²tÌ²rÌ²oÌ²lÌ²-Ì²DÌ² (if iÌ²gÌ²nÌ²oÌ²rÌ²eÌ²eÌ²oÌ²fÌ²
     is not set) for the C-shell, csh(1)).

     Certain interactive commands, such as vi(1), create garbage in the typeâ
     script file.  The ðð°ð¿ð¶ð½ð utility works best with commands that do not maâ
     nipulate the screen.  The results are meant to emulate a hardcopy terminal,
     not an addressable one.

ððððððððððð
     The following environment variables are utilized by ðð°ð¿ð¶ð½ð:

     SCRIPT
            The SCRIPT environment variable is added to the sub-shell.  If
            SCRIPT already existed in the users environment, its value is overâ
            written within the sub-shell.  The value of SCRIPT is the name of
            the tÌ²yÌ²pÌ²eÌ²sÌ²cÌ²rÌ²iÌ²pÌ²tÌ² file.

     SHELL  If the variable SHELL exists, the shell forked by ðð°ð¿ð¶ð½ð will be
            that shell.  If SHELL is not set, the Bourne shell is assumed.
            (Most shells set this variable automatically).

ððð ðððð
     csh(1) (for the hÌ²iÌ²sÌ²tÌ²oÌ²rÌ²yÌ² mechanism)

ððððððð
     The ðð°ð¿ð¶ð½ð command appeared in 3.0BSD.

     The -ð±, -ð½ and -ð¿ options first appeared in NetBSD 2.0 and were ported to
     FreeBSD 9.2.

ðððð
     The ðð°ð¿ð¶ð½ð utility places ð²ðð²ð¿ðððµð¶ð»ð´ in the log file, including linefeeds
     and backspaces.  This is not what the naive user expects.

     It is not possible to specify a command without also naming the script file
     because of argument parsing compatibility issues.

     When running in -ð¸ mode, echo cancelling is far from ideal.  The slave terâ
     minal mode is checked for ECHO mode to check when to avoid manual echo logâ
     ging.  This does not work when the terminal is in a raw mode where the proâ
     gram being run is doing manual echo.

     If ðð°ð¿ð¶ð½ð reads zero bytes from the terminal, it switches to a mode when it
     only attempts to read once a second until there is data to read.  This preâ
     vents ðð°ð¿ð¶ð½ð from spinning on zero-byte reads, but might cause a 1-second
     delay in processing of user input.
