Script interpreter for minicom

[email protected]:~# man runscript
RUNSCRIPT(1)                General Commands Manual               RUNSCRIPT(1)

       runscript - script interpreter for minicom

       runscript scriptname [logfile [homedir]]

       runscript is a simple script interpreter that can be called from within
       the minicom communications program to automate tasks like logging in to
       a Unix system or your favorite BBS.

       The  program  expects  a  script name and optionally a filename and the
       user's home directory as arguments, and it expects that it's input  and
       output are connected to the "remote end", the system you are connecting
       to. All messages from runscript meant for the local screen are directed
       to  the  stderr  output. All this is automatically taken care of if you
       run it from minicom.  The logfile and  home  directory  parameters  are
       only  used to tell the log command the name of the logfile and where to
       write it. If the homedir is omitted, runscript uses the directory found
       in the $HOME environment variable. If also the logfile name is omitted,
       the log commands are ignored.

       Runscript recognizes the following commands:

            expect   send     goto     gosub    return   !<   !
            exit     print    set      inc      dec      if   timeout
            verbose  sleep    break    call     log

       send <string>
            <string> is sent to the modem. It is followed by a '\r'.  <string>
            can be:
              - regular text, e.g. 'send hello'
              - text enclosed in quotes, e.g. 'send "hello world"'

            Within <string> the following sequences are recognized:
                \n - newline
                \r - carriage return
                \a - bell
                \b - backspace
                \c - don't send the default '\r'.
                \f - formfeed
                \^ - the ^ character
                \o - send character o (o is an octal number)

            Control characters can be used in the string with the ^ prefix (^A
            to ^Z, ^[, ^ ^], ^^ and ^_). If you need to send the ^  character,
            you must prefix it with the \ escape character.
            Octal characters are either four-digit or delimited by a non-digit
            character, e.g. the null character may  be  sent  with  \0000  and
            'send 1234' is equivalent to 'send \0061234'.
            Also  $(environment_variable)  can  be  used, for example $(TERM).
            Minicom passes  three  special  environment  variables:  $(LOGIN),
            which  is the username, $(PASS), which is the password, as defined
            in the proper entry of the dialing directory, and $(TERMLIN) which
            is  the  number  of actual terminal lines on your screen (that is,
            the statusline excluded).

       print <string>
            Prints <string> to the local screen. Default followed  by  '\r\n'.
            See the description of 'send' above.

            Declares  a  label (with the name 'label') to use with goto or go-

       goto <label>
            Jump to another place in the program.

       gosub <label>
            Jumps to another place in the program. When the statement 'return'
            is  encountered, control returns to the statement after the gosub.
            Gosub's can be nested.

            Return from a gosub.

       ! <command>
            Runs a shell for you in which 'command' is  executed.  On  return,
            the  variable  '$?'  is set to the exit status of this command, so
            you can subsequently test it using 'if'.

       !< <command>
            Runs a shell for you in which 'command' is  executed.  The  stdout
            output  of the command execution will be sent to the modem. On re-
            turn, the variable '$?' is set to the exit status of this command,
            so you can subsequently test it using 'if'.

       exit [value]
            Exit from "runscript" with an optional exit status. (default 1)

       set <variable> <value>
            Sets the value of <variable> (which is a single letter a-z) to the
            value <value>. If <variable> does not exist, it will  be  created.
            <value> can be a integer value or another variable.

       inc <variable>
            Increments the value of <variable> by one.

       dec <variable>
            Decrements the value of <variable> by one.

       if <value> <operator> <value> <statement>
            Conditional  execution  of <statement>. <operator> can be <, >, !=
            or =.  Eg, 'if a > 3 goto exitlabel'.

       timeout <value>
            Sets the global timeout. By default, 'runscript' will  exit  after
            120  seconds. This can be changed with this command. Warning: this
            command acts differently within an 'expect'  statement,  but  more
            about that later.

       verbose <on|off>
            By  default,  this is 'on'. That means that anything that is being
            read from the modem by 'runscript', gets  echoed  to  the  screen.
            This is so that you can see what 'runscript' is doing.

       sleep <value>
            Suspend execution for <value> seconds.

              expect {
                pattern  [statement]
                pattern  [statement]
                [timeout <value> [statement] ]
            The  most  important command of all. Expect keeps reading from the
            input until it reads a pattern that matches one of  the  specified
            ones.   If expect encounters an optional statement after that pat-
            tern, it will execute it. Otherwise the default is to  just  break
            out  of  the expect. 'pattern' is a string, just as in 'send' (see
            above).  Normally, expect will timeout  in  60  seconds  and  just
            exit, but this can be changed with the timeout command.

            Break  out  of an 'expect' statement. This is normally only useful
            as argument to 'timeout' within an expect, because the default ac-
            tion of timeout is to exit immediately.

       call <scriptname>
            Transfers  control  to  another script file. When that script file
            finishes without errors, the original script will continue.

       log <text>
            Write text to the logfile.

       If you want to make your script to exit minicom (for example  when  you
       use  minicom  to dial up your ISP, and then start a PPP or SLIP session
       from a script), try the command "! killall  -9  minicom"  as  the  last
       script  command.  The  -9 option should prevent minicom from hanging up
       the line and resetting the modem before exiting.
       Well, I don't think this is enough information to make you  an  experi-
       enced  'programmer'  in  'runscript', but together with the examples it
       shouldn't be too hard to write some useful script files. Things will be
       easier  if  you  have  experience  with BASIC.  The minicom source code
       comes together with two example scripts, scriptdemo and unixlogin.  Es-
       pecially the last one is a good base to build on for your own scripts.


       Runscript should be built in to minicom.

       xminicom minicom-options

       Xminicom  is a script wrapper around minicom.  It tries to find a color
       capable xterm or rxvt on your system, and then runs minicom with the -c
       (color) flag in a terminal session.

       See minicom (1).
