Some variants of Unix support options such as -n and -e. These are not standard due to historical incompatibilities between BSD and System V; the printf command can be used in situations where this is a problem.

Using ANSI escape code SGR sequences, compatible terminals can print out colored text:

FGRED=`echo "\033[31m"` FGCYAN=`echo "\033[36m"` BGRED=`echo "\033[41m"` FGBLUE=`echo "\033[35m"` BGGREEN=`echo "\033[42m"` NORMAL=`echo "\033[m"` and after : echo "${FGBLUE} Text in blue ${NORMAL}" echo "Text normal" echo "${BGRED} Background in red" echo "${BGGREEN} Background in Green and back to Normal ${NORMAL}"

Famous quotes containing the word usage:

“I am using it [the word ‘perceive’] here in such a way that to say of an object that it is perceived does not entail saying that it exists in any sense at all. And this is a perfectly correct and familiar usage of the word.”
—A.J. (Alfred Jules)

“Pythagoras, Locke, Socrates—but pages
Might be filled up, as vainly as before,
With the sad usage of all sorts of sages,
Who in his life-time, each was deemed a bore!
The loftiest minds outrun their tardy ages.”
—George Gordon Noel Byron (1788–1824)
