tput rmam

will disable line wrapping so that long lines are truncated to width of the terminal ($COLUMNS).

tput smam

will re-enable wrapping.

I've always used tput in bash scripts but I guess it works on the command line too.

Doesn't work in all terminals.

See http://www.gnu.org/software/termutils/manual/termutils-2.0/html_chapter/tput_1.html

Know a better way?

If you can do better, submit your command here.

What others think

function is bash specific. Also you don't need to set COLS, just:

nowrap() { cut -c-$(tput cols); }

Note however that will mess up if terminal escape codes are in your data. It may also mess up with non displaying multibyte characters like combining chars for example.

Hmm are there any terminals that support a nowrap setting?

Comment by pixelbeat 258 weeks ago

function works in ksh, it's not bash specific.

thanks to have reduced this function, don't know why i did it like this ^_^

this function is for a quickview, no matters multibyte characters i think.

thanks for your comments.

Try this

function nowrap { export COLS=`tput cols` ; cut -c-$COLS ; unset COLS ; echo -ne "\e[0m" ; }

Here a example

#!/bin/bash function nowrap { export COLS=`tput cols` ; cut -c-$COLS ; unset COLS ; echo -ne "\e[0m" ; } echo -ne "\e[1;31mNote however that will mess up if terminal escape codes are in your data. It may also mess up with non displaying multibyte characters like combining chars for example.\nHmm are there any terminals that support a nowrap setting?\e[0m" | nowrap
