inverted text on tty 1

[scienzia]

Hi,

I have a simple question:

is it possible to write in a tty some text inverted as if it was highlighted?

Thanks in advance

yes, with ascii codes. See

http://www.fh-jena.de/~gmueller/Kurs_halle/esc_vt100.html

and pay attention to "Set Display Attributes".

e.g.:
[tt]
printf "\033[7mHello World\033[0m"
[/tt]

Cheers.

The more general solution (not specific to a Linux console) is to use "tput"

For example (straight from "man tput"):

bold=`tput smso`;offbold=`tput rmso`

You can then use the variables to turn on and off attributes.

echo "This is $bold bold $offbold but this is not"

Note that you don't need "-e" because this puts out the actual binary values.

It's also a bit easier than remembering escape sequences, and has the advantage of portability: if the If you want to store something for use somewhere else, you can give the terminal type:

bold=`tput -Tlinux smso`

etc.

I prefer the first because I use it in a program, and it is easier to insert some digits in output than executing a program.

Thanks anyway
