Blatantly borrowed from Bill Hassell:

export HB=$(tput dim 2>/dev/null) # dim text
export HV=$(tput smso 2>/dev/null) # 1/2 bright inverse
export IV=$(tput bold 2>/dev/null) # inverse
export UL=$(tput smul 2>/dev/null) # underline
export BL=$(tput blink 2>/dev/null) # blink
export EL=$(tput el 2>/dev/null) # clear to end of line
export ED=$(tput ed 2>/dev/null) # clear to end of display
export EE=$(tput sgr0 2>/dev/null) # end all enhancements
echo "normal $HV smso $HB dim $IV bold $UL smul $BL blink $EE normal"

BOLD=$(tput bold)
NORM=$(tput sgr0)

echo "${BOLD}\c"
This should be bold.
echo "${NORM}\c"
This should be normal

Not all terminals support bold so you should probably use BOLD=(tput smso) nad NORM=(tput rmso)" instead but you could test it see if bold is available using the tput command. Man tput , terminfo for details.

Exist any option for brightnes

It depends upon the particular terminal type.

Hi:

> Exist any option for brightnes

As Clay notes, everything depends upon your terminal type. If you look at the 'terminfo(4)' and 'tput(1)' manpages, you will find that "bold" is considered equivalant to "extra-bright".

Thanks Gurus

My question is what is the option for the cursor display and not display

Re: BOLD LETTERS FOR SHELL SCRIPT

A. Clay Stephenson — Thu, 29 Nov 2007 13:04:52 GMT

The answer is still "man terminfo". ... and it still depends upon the TERM type whether or not this is possible.

Attached is ttyenhance, a simple script to show the most common video enhancements available on the current terminal emulator (hardly anyone has a real terminal these days). As mentioned, the terminfo man page (one of the longest in all of HP-UX -- trivia: gated.conf is the longest) is extensive and defines a generic way to access the multitude of terminal features from literally hundreds of different models. All of this works when you don't lie about your terminal -- which means TERM=vt100 is never allowed, you must have ttytype set your TERM and related values, like this in .profile or /etc/profile:

eval $(ttytype -sa)

ttyenhance graphically shows the video features but is just using the Curses library to figure out what codes or escape sequences are needed for this terminal. Related to ttytype are the untic and tpu commands. untic shows (in terminfo talk) whether a feature exists and if so, shows to activate each feature.

Bill,

Looks like the attachment didn't

You're right!! Must be something wrong with my mouse. ;-)

Here's the attachment.

OK, attachments are broken again...here's the code:

#!/usr/bin/sh
# Bill Hassell Jun 2004

# Script to display terminal characteristics using Curses

# usage: ttyenhance [ any text will turn off ttytype polling ]
# Run with any text to bypass the ttytype polling and use
# the current value of $TERM, $LINES and $COLUMNS

set -u
PATH=/usr/bin

if [ $# -gt 0 ]
then
echo
echo "Current settings: TERM=$TERM, LINES=$LINES, COLUMNS=$COLUMNS"
else
eval $(ttytype -s)
echo
echo "ttytype says this terminal is a $TERM, LINES=$LINES, COLUMNS=$COLUMNS"
fi

# see if there is a terminal like this defined

tput sgr0 > /dev/null 2>&1
if [ $? -ne 0 ]
then
echo "$TERM is unknown to the terminfo database on this computer"
exit
fi

HB=$(tput dim) # dim text
HV=$(tput smso) # 1/2 bright inverse
IV=$(tput bold) # inverse
UL=$(tput smul) # underline
BL=$(tput blink) # blink
EE=$(tput sgr0) # end enhancements

echo
echo "Typical names:"
echo "\t$EE Normal $IV Inverse $EE $HB Dim $EE $BL Blink $EE $HV halfbrite $EE $UL underline $EE"

echo
echo "Curses capname (tput)"
echo "\t$EE SGR0 $IV BOLD $EE $HB DIM $EE $BL BLINK $EE $HV SMSO $EE $UL SMUL $EE"
echo
