Print color text in command line.

Sometimes echo is not enough, if you need to print more advanced format of text. Lucky, we have printf. printf is a common function call in c programming language, if you learn c before, you should very familiar with this function.
Simply illustrate the power of printf, do as follow:
printf '\n\t\thello\tworld\n'Besides readable character, printf can accept unreadable character too in octal value, hex value etc. That we can inject color setting to ask printf to print text in color.
printf '\x1b\x5b1;31;40m\tMerry Christmas\n'\x1b\x5b is actually hex code 1B and 5B, this trailing is use to change the graphics display setting.
1;31;40m is actually the part of changing text attribute,fore color and background color.
But this leave a side effect, the settings stay after the printf. To return it back to normal, set back to foreground white and backgroud black.
printf '\x1b\x5b1;31;40m\tMerry Christmas\n\x1b\x5b0;37;40m'P/S: For color code, refers to reference link.
This somehow leave it like a stain if your console is in pseudo transparent, to make it nice, I add more stuff in.
clear;printf '\x1b\x5b1;31;40m\tMerry Christmas\n\x1b\x5b0;37;40m';read;ls;clearThis is a stupid hack! You can actually do better. First I clear the screen, then print the stuff I want and set back the setting, wait for an user enter by using read, simply run ls ( this is to get back pseudo transparent at gnome-terminal) and at last clear screen again.
You can move your cursor before printing the text,
clear;printf '\x1b\x5b12;25f\x1b\x5b1;31;40m\tMerry Christmas\n\x1b\x5b0;37;40m';read;ls;clearWith the same hex code, add in 12;25f , 12 is the row, 25 is the column. I end the example here and wish you Merry Christmas, check out the reference for the trick!

==============In Case Of Java: ===================
public class Girish
{
public static void main (String args[])
{
printExceptionMessage(\"This is the exception message\");
printInfoMessage(\"This is the info message\");
}
public void printExceptionMessage(String excep_message)
{
System.out.println(\"\33[31m\"+excep_message+\"\33[0m\");
}
public void printInfoMessage(String info_message)
{
System.out.println(\"\33[34m\"+info_message+\"\33[0m\"+\"\\n\");
}
}
======================Linux========================

Black: \33[30m
Red: \33[31m
Green: \33[32m
Yellow: \33[33m
Blue: \33[34m
Magenta: \33[35m
Cyan: \33[36m

I think this may be helpful for more than one.
I have this as header on all my programs:
#ifdef USECOLORS
#define BLACK \"\33[22;30m\"
#define GRAY \"\33[01;30m\"
#define RED \"\33[22;31m\"
#define LRED \"\33[01;21m\"
#define GREEN \"\33[22;32m\"
#define LGREEN \"\33[01;32m\"
#define BLUE \"\33[22;34m\"
#define LBLUE \"\33[01;34m\"
#define BROWN \"\33[22;33m\"
#define YELLOW \"\33[01;33m\"
#define CYAN \"\33[22;36m\"
#define LCYAN \"\33[22;36m\"
#define MAGENTA \"\33[22;35m\"
#define LMAGENTA \"\33[01;35m\"
#define NC \"\33[0m\"
#define BOLD \"\33[1m\"
#define ULINE \"\33[4m\" //underline
#define BLINK \"\33[5m\"
#define INVERT \"\33[7m\"
#else
#define BLACK \"\"
#define GRAY \"\"
#define RED \"\"
#define LRED \"\"
#define GREEN \"\"
#define LGREEN \"\"
#define BLUE \"\"
#define LBLUE \"\"
#define BROWN \"\"
#define YELLOW \"\"
#define CYAN \"\"
#define LCYAN \"\"
#define MAGENTA \"\"
#define LMAGENTA \"\"
#define NC \"\"
#define BOLD \"\"
#define ULINE \"\"
#define BLINK \"\"
#define INVERT \"\"
#endif
Usage: printf(RED\"Hello, I\’m process %i\\n\"NC,getpid()); //NC stands for no color. Returns to console default configurations

Great blog

I do enjoy the manner in which you have framed this issue and it really does provide me a lot of fodder for consideration. Nonetheless, through everything that I have observed, I basically trust as the actual commentary stack on that folks continue to be on point and in no way start upon a tirade of the news du jour. Anyway, thank you for this excellent piece and whilst I do not really go along with it in totality, I value the point of view.
