Shell Programming and Scripting

Good day all

I am looking for a way to change colours in a text file that get tailed.
I have tried using tput, however this does not seem to work. terminal type is using putty and vt100 emulation.

Any ideas.

Thanks

You can use:
setterm -foreground ... | od -tc
to see control sequences for changing these attributes.

thanks for the reply,. I forgot to mention that it is for a AIX system. setterm seems not to be available on this platform.

Regards

I don't know if this is the right place for my post.
Could someone tell me how to put on and put off the colour in vi editor.
Also what is an AIX system

I didn't understood what you wanted fully. If you want to change the display colors, look for DIR_COLORS or DIRCOLORS.xterm file in /etc. It defines the color mappings. Not sure if it exists in AIX.

Also, try echo -e "\033[30;47m" ( terminal command that changes colors. Its specific to terminal type)

mappings defined in my system(linux) are

# Attribute codes:
# 00=none 01=bold 04=underscore 05=blink 07=reverse 08=concealed
# Text color codes:
# 30=black 31=red 32=green 33=yellow 34=blue 35=magenta 36=cyan 37=white
# Background color codes:
# 40=black 41=red 42=green 43=yellow 44=blue 45=magenta 46=cyan 47=white

echo -e "\033[05;30;47m Hello" causes text to blink and 04 causes text to be underlined as mentioned above. Hope this helps.

I could not see colour when i am using the vi editor.

When i write in the vi editor some times for some srtings like "echo" ,"do", "exit","where" all these words come in the white clolour
Like
echo " Hello "
if [ $1 > $2 ]
do
echo " great "
exit.

And in some enviornments it won't be there.How to siwtch it on or off.

The terminal command that I mentioned works only when you are at the shell prompt and its also dependent on what terminal is being used. For vi color settings try:

:syntax on or :synatx enable( To enable command highlighting)
I think this is only a feature of vim, might not work with vi. So check first whether vi command on your system is actually an alias to vim or not.
