Top Forums Shell Programming and Scripting Using echo to create a script Post 302328196 by vgersh99 on Tuesday 23rd of June 2009 05:01:23 PM

FYI:
Code:
     << [-]word
           The shell input is read up to a line that is the  same
           as word, or to an EOF. No parameter substitution, com-
           mand substitution, or file  name  generation  is  per-
           formed  on  word.  The  resulting  document,  called a
           here-document, becomes  the  standard  input.  If  any
           character  of  word  is  quoted,  no interpretation is
           placed upon the characters of the document. Otherwise,
           parameter  and command substitution occur, \NEWLINE is
           ignored, and \ must be used to quote the characters \,
           $,  `,  and  the  first  character  of  word.  If - is
           appended to <<, then all  leading  tabs  are  stripped
           from word and from the document.

NAME

       script - Makes a transcript of terminal session

SYNOPSIS

       script [-a] [file]

       The script command makes a transcript of everything printed on your terminal.

OPTIONS

       Appends the transcript to file rather than writing it to file.

OPERANDS

       The name of an output file that will contain the transcript of the session.  If this parameter is omitted, the file typescript is written.

DESCRIPTION

       The transcript is written to file, or appended to file if the -a option is given.  If no file name is given, the transcript is saved in the
       file typescript.

       The script ends when the forked shell exits.

       This program is useful when you are using a CRT and want a hard-copy record of the dialog (for example, a technical writer might create	an
       example of a working session this way).

       If you specify the -a option and the file does not exist, it is created.

       If you do not specify the -a option and the file exists, it is replaced.

RESTRICTIONS

       The  script command requires a streams based terminal.  In single user mode, streams may not be enabled.  Under these circumstances, script
       will exit with no action.  If you are the superuser and need to run this command in single user mode, use the  following  special  instruc-
       tions.

   Enabling Streams
       If it is necessary to enable a streams environment in the single user mode, enter the command /sbin/init.d/streams.  This command is avail-
       able to the superuser only.
