My script is almost perfect but i'm stuck at the last hurdle:
I need a sort of modified 'echo' which truncates its output to the width of the terminal
I can find the terminal's width with 'stty size' but i dont know how to then convert input lines to that printing length:
The lines may contain multiple 'randomly' placed tab characters
The lines may contain special colour formatting escape sequences which should not effect the 'length' of the line
Context:
This is a 'find in files' utility which interactively finds using 'find' and 'grep' regex patterns in the directory subtree, opens the file in my favourite editor at the line wit the match, and interactively modifies the search pattern and re-performs the search. Complete with pretty coloured output. Here i'm trying to prevent long lines that get found from spilling onto new lines in the terminal and disrupting the formatted output
where <col> are the invisible coloured terminal formatting bits and <line /> is the only part which is allowed to be truncated (we assume the terminal is never thin enough to not print the 2 numeric fields)
None, one, or both numeric fields may exceed tab width under normal operation normal
Hi all
The makefile of a large project produces hundreds of lines of output, which I can't look at any more when the build is finished. If I simply redirect the output to a file, I can't see the progress of the building process...

How can I write to another user's pseudo tty, but not to its current prompt position (as in open("/dev/pts007", ...) followed by write() ). Instead I would like to write to the top center of the screen using color red, for example. Like curses, but from another console. (6 Replies)

Hey,
How can I transfer the terminal output to a file ?

Hello,

script
SCRIPT(1) BSD General Commands Manual SCRIPT(1)NAME
script -- make typescript of terminal session
SYNOPSIS
script [-adfpqr] [-c command] [file]
DESCRIPTION
script makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of an interactive
session as proof of an assignment, as the typescript file can be printed out later with lpr(1).
If the argument file is given, script saves all dialogue in file. If no file name is given, the typescript is saved in the file typescript.
Option:
-a Append the output to file or typescript, retaining the prior contents.
-c command
Run the named command instead of the shell. Useful for capturing the output of a program that behaves differently when associated
with a tty.
-d When playing back a session with the -p flag, don't sleep between records when playing back a timestamped session.
-f Flush output after each write. This is useful for watching the script output in real time.
-p Play back a session recorded with the -r flag in real time.
-q Be quiet, and don't output started and ended lines.
-r Record a session with input, output, and timestamping.
The script ends when the forked shell exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-d (if ignoreeof is not
set) for the C-shell, csh(1)).
Certain interactive commands, such as vi(1), create garbage in the typescript file. script works best with commands that do not manipulate
the screen, the results are meant to emulate a hardcopy terminal.
ENVIRONMENT
The following environment variable is used by script:
SHELL If the variable SHELL exists, the shell forked by script will be that shell. If SHELL is not set, the Bourne shell is assumed. (Most
shells set this variable automatically).
SEE ALSO csh(1) (for the history mechanism).
HISTORY
The script command appeared in 3.0BSD.
BUGS
script places everything in the log file, including linefeeds and backspaces. This is not what the naive user expects.
