script output in BOLD

Alan Meyer_4 — Thu, 01 Dec 2005 12:53:51 GMT

I should know this, but I don't... How do I make portions of the output of a shell script to appear BOLD on the screen as well as print in BOLD when redirected to the printer?

ie... (text shown in CAPS are to be bold)

now is the TIME for all good men

TO COME TO THE AID OF THEIR COUNTRY...

echo "now is the \c"
tput bold
echo "TIME\c"
tput rmso
echo " for all good men"
tput bold
echo "TO COME TO THE AID OF THEIR COUNTRY..."
tput rmso

Man tput, terminfo for details.

Alan,

Try a man on "tput".

I've set the following in my script-
export ttybold=`tput bold` ; export ttynorm=`tput rmso`

Then I can do
echo "now is the ${ttybold}TIME${ttynorm} for all good men"

how do you incorporate that into a printf statement like:

printf "%-10s: %-10s %-16s %-16s %-s\n" $NODE $LVLNB $PVD1 $PVD2 $NOTE

where the whole line is to be BOLD? but nothing before or nothing after?

tput smso
printf "%-10s: %-10s %-16s %-16s %-s\n" $NODE $LVLNB $PVD1 $PVD2 $NOTE
tput rmso

Hi Alan:

How about :

# XON=`tput bold`;XOFF=`tput rmso`;printf "%sI said %s %-s\n" ${XOFF}

Doing it in echo mode works great, but,...

the suggestions for incorporating it into a printf have not worked.

Oh, I should have read your post more carefully. The sequences needed to bold output to the terminal have nothing to do with those that are sent to the printer -- or if they do, it's purely accidental.

However, you can create terminfo entries for printers as well and invoke tput with a -T option to indicate the printer type. Note that you will need to know the printer model and have a terminfo entry for each type. The command that converts a text file into a terminfo entry is 'tic'; 'untic' does the reverse. Man tic and untic for details. You are now getting into areas that UNIX ain't real good at doing. The application is supposed to take full control of this kind of printer output.

and the key to making your printf's work is them there quotes -- which is always good shell programming practice.

typeset BOLD=$(tput bold)
typeset NORMAL=$(tput rmso)
typeset VAR1="This is some text; "
typeset VAR2="this here is some more text."

printf "%s%s %s%s\n" "${BOLD}" "${VAR1}" "${VAR2}" "${NORMAL}"

printf "(Normal) %s %s\n" "${VAR1}" "${VAR2}"

Hi Alan:

I agree with Clay regarding the use of double quotes, but bungled my post anyway when pasting it. I should have written:

# XON=`tput smso`;XOFF=`tput rmso`;printf "%sI said %s %-s %s\n" ${XON} hello ${XOFF} there

I did *not* encapsulate the arguments in double quotes here or before.

Aside from correcting my bad pasting from the first post, I *do* note that using `tput bold` to turn on "bold" emphasis doesn't get turned off with `tput rmso`, at least under vt220 emulation. *However* you can see the effect correctly by using `tput smso` as I have in this post to turn on reverse video.

Redirecting any of this to printers won't work, of course.

Regards!
