Create blinking text with echo and escape characters I have learned about formatting options used in shell scripting, which go like this: \033[37:40mAnyText\033[0m Now I want to echo some text like this: echo -e "SomeText \033[5;31;47mMoreText\033[0m" The integer 5 is for blinking. The other formatting works, but not the blinking -- why?

This is a terminal independent way of enabling the blinking attribute. If it doesn't work then either you've mis-set your terminal type, it's not enabled in the terminal characteristics, or it's simply not supported:


tput blink
echo hello, world
tput sgr0


The `terminfo` database is well worth perusing (not bedtime reading, mind) to find semi-readable names for terminal escape code sequences.
