Echo (command) - Usage Example

Usage Example

$ echo This is a test. This is a test. $ echo "This is a test." > ./test.txt $ < ./test.txt This is a test.

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:

“...Often the accurate answer to a usage question begins, “It depends.” And what it depends on most often is where you are, who you are, who your listeners or readers are, and what your purpose in speaking or writing is.”
—Kenneth G. Wilson (b. 1923)

“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)
