MESSAGES(3)						  libbash messages Library Manual					       MESSAGES(3)

NAME

     messages -- libbash library that implements a set of functions to print standard status messages

SYNOPSIS

     printOK	 [indent]
     printFAIL	 [indent]
     printNA	 [indent]
     printATTN	 [indent]
     printWAIT	 [indent]

DESCRIPTION

   General
     messages is a collection of functions to print standard status messages - those [ OK ] and [FAIL] messages you see during Linux boot process.

     The function list:
	   printOK	    Prints a standard [ OK ] message (green)
	   printFAIL	    Prints a standard [FAIL] message (red)
	   printNA	    Prints a standard [ N/A] message (yellow)
	   printATTN	    Prints a standard [ATTN] message (yellow)
	   printWAIT	    Prints a standard [WAIT] message (yellow)

     Detailed interface description follows.

   indent
     Column to move to before printing.

     Default indent is calculated as TTY_WIDTH-10. If current tty width can not be determined (for example, in case of serial console), it
     defaults to 80, so default indent is 80-10=10

FUNCTIONS DESCRIPTIONS

   printOK [indent]
     Prints a standard [ OK ] message (green)

   printFAIL [indent]
     Prints a standard [FAIL] message (red)

   printNA [indent]
     Prints a standard [ N/A] message (yellow)

   printATTN [indent]
     Prints a standard [ATTN] message (yellow)

   printWAIT [indent]
     Prints a standard [WAIT] message (yellow)

EXAMPLES

     Run a program named MyProg, and report it's success or failure:

	      echo -n 'Running MyProg...'
	      printWAIT
	      if MyProg ; then
		      printOK
	      else
		      printFAIL
	      fi
