Color is selected by adding a special sequence-basically a numerical value between "/E [" and "m. If more than one numeric code is specified, separate them with semicolons.
Echo-e "/E [31; 40 m"
The first digit (31) is the foreground color (red), and the second digit is (40) the background color (black)
Echo-e "/E [0 m"
We need to use the "/E [0 m" sequence to reset the color to the normal value.
/033 [30 m --/033 [37 m sets the foreground color (font color)
/033 [30 m change the color of the character to black
/033 [31 m change the color of the character to red
/033 [32 m change the color of the character to green
/033 [33 m change the color of the character to light red
/033 [34MChange the color of the character to blue.
/033 [35 m change the character color to purple
/033 [36 m change the character color to light blue
/033 [37 m change the color of the character to gray
/033 [40 m --/033 [47 m set the background color
/033 [40 m set the background color to black
/033 [41 m set the background color to red
/033 [42 m set the background color to green
/033 [43 m set the background color to light red
/033 [44 m set the background color to blue
/033 [45 m set the background color to purple
/033 [46 m set the background color to light blue
/033 [47 m set the background color to gray
For example, echo-ne "/033 [32 m" can change the color of the character to green.
