Need help on SCRIPT(1M) utility
Post 302097274 by matrixmadhan on Thursday 23rd of November 2006 02:49:42 AM

This is really a interesting property of terminals to work with ( master and a slave)
Even once I tried to write my own version of script command,
with date-time stamping, userid and hostname stamping.
As said it would capture everything, literally everything.
Where the problem arises is,
we need to derive the pattern of so-called junk characters all those - ^v, ^M stuff.
mostly for utilities where it execs shell and has the tty controls itself rather giving it to the shelf.
Steps I went through
1) Determine the pattern and give a bulk replace
2) All such patterns to be replaced in a run
3) Such patterns with vi empty lines and command line utility would be easier to determine
4) Difficult part comes with the utilities which run as curses program.
Still am not successful with the 4th pt.

BWILD(8) Network backup, utilities BWILD(8) NAME
bwild - Bacula's 'wildcard' engine SYNOPSIS
bwild [options] -f <data-file> DESCRIPTION
This manual page documents briefly the bwild command. This is a simple program that will allow you to test wild-card expressions against a file of data. OPTIONS
A summary of options is included below. -? Show version and usage of program. -d nn Set debug level to nn. -dt Print timestamp in debug output -f <data-file> The data-file is a filename that contains lines of data to be matched (or not) against one or more patterns. When the program is run, it will prompt you for a wild-card pattern, then apply it one line at a time against the data in the file. Each line that matches will be printed preceded by its line number. You will then be prompted again for another pattern. Enter an empty line for a pattern to terminate the program. You can print only lines that do not match by using the -n option, and you can suppress printing of line numbers with the -l option. -n Print lines that do not match -l Suppress lines numbers. -i use case insensitive match.
