Okay, got it. That is just the printf syntax that doesn't support the "\e" shortcut.

This will work on older AIX, Solaris or anything:
Code:
printf "\033[1mbold\033[0m"

The tput command is only required (by the POSIX standard) to support three operands, clear, init and reset. You cannot count on anything beyond that.

Most do support a lot more, but there are two different versions. One uses the termcap database, the other uses terminfo. The commands are not the same; what works on one does not always work on the other.

On one system I use, "tput smso; echo qwerty; tput rmso" will print 'qwerty' in reverse; on another, it is unchanged.

This is the code to use:

Code:
printf "\e[1m"  ## bold on
printf "\e[0m"  ## bold (and other attributes) off

I use a terminal emulator called Token2Shell when logging into my linux server from my XP laptop. This code does not work with it, I certainly see nothing in bold.

However the initial tput statements at the head of this post do work.

Code:
bold=`tput smso`
offbold=`tput rmso`

Interesting. Please post the output of
Code:
bold=`tput smso`
offbold=`tput rmso`
echo "${bold}" | hexdump -C
echo "${offbold}" | hexdump -C

so we can figure out what weird terminal it thinks it is Smilie

...did you try the \033 syntax, instead of \e? Non-ANSI terminals are extremely rare these days...

OK

Nothing appeared as bold with this: -

Code:

poweredge:/home/brad>bold=`tput smso`
poweredge:/home/brad>offbold=`tput rmso`
poweredge:/home/brad>echo "${bold}" | hexdump -C
00000000 1b 5b 37 6d 0a |.[7m.|
00000005
poweredge:/home/brad>echo "${offbold}" | hexdump -C
00000000 1b 5b 6d 0a |.[m.|
00000004

This does not print bold either: -
Code:
 
poweredge:/home/brad>printf "\033[1mbold\033[0m\n"
bold

I said this does print bold but on reflection I may be wrong, when I tried it tonight the word bold was inverted with its background although I was sure it printed bold the other night. Do you think the previous statements could have changed the behaviour?: -

Code:
 
poweredge:/home/brad>offbold=`tput rmso` 
poweredge:/home/brad>bold=`tput smso` 
poweredge:/home/brad>echo "This word is ${bold}bold${offbold} and this is not"
This word is bold and this is not

I don't know what to make of the hexdump so would be glad for an explanation of what it means.

Token2Shell is a funny little terminal emulator that does not seem to let you set the terminal type.
