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)

script
SCRIPT(1) BSD General Commands Manual SCRIPT(1)NAME
script -- make typescript of terminal session
SYNOPSIS
script [-a] [-k] [-q] [-t time] [file [command ...]]
DESCRIPTION
The script utility 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.
If the argument command ... is given, script will run the specified command with an optional argument vector instead of an interactive shell.
Options:
-a Append the output to file or typescript, retaining the prior contents.
-k Log keys sent to program as well as output.
-q Run in quiet mode, omit the start and stop status messages.
-t time Specify time interval between flushing script output file. A value of 0 causes script to flush for every character I/O event. The
default interval is 30 seconds.
The script ends when the forked shell (or command) 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. The script utility works best with commands that do not
manipulate the screen. The results are meant to emulate a hardcopy terminal, not an addressable one.
ENVIRONMENT
The following environment variable is utilized 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
The script utility places everything 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 -k mode, echo cancelling is far from ideal. The slave terminal mode is checked for ECHO mode to check when to avoid manual
echo logging. This does not work when in a raw mode where the program being run is doing manual echo.
