Ah. OK. I have seen this in other scripts, so thought it was necessary. Interestingly, removing the braces has fixed the lack of tabs and linefeeds, so perhaps braces in this form DO do something.

Sorry, That's a vestigial command from days gone by. I've removed it.

The script now seems to be working as it should now. Many thanks.

So, short of removing asterisks in the target file as I have done, how do you escape this behaviour, to deal with text files/strings that contain asterisks?

One last thing: Do I need to make any changes if the input $FILENAME isn't the name of a file, but is simply a string containing all the data?

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
