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

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]

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

printWAIT
if MyProg ; then
printOK
else
printFAIL
fi
