Simple awk script question
Hi,
I'm a total beginner at awk and hope someone can advise what I have done wrong in the following script:
I have a file which (to simplify things) may be something like this
Fred Smith and Sue Brown
Joe Jones and Jane Watts
Sally Green and Jim O?
Connor
Freda O?
Reiley and Pat O?
Connell
Peter Parker and Tina Williams
Notice some of the names are split. I need the file to look like this:
Fred Smith and Sue Brown
Joe Jones and Jane Watts
Sally Green and Jim O?Connor
Freda O?Reiley and Pat O?Connell
Peter Parker and Tina Williams
I had a go at writing the following:
cat input_file | awk '
BEGIN { totalline=""; flag=0 }
/\?\047$/ { totalline=totalline $0; flag=1 }
{ if (totalline == "" ) print $0 }
{ if (totalline != "" && flag == 0 ) print totalline, $0; totalline="" }
{ flag=0 }
' > output_file
But the output is
Fred Smith and Sue Brown
Joe Jones and Jane Watts
Connor
Connell
Peter Parker and Tina Williams
I'm not totally comfortable with awk syntax but I think I may not be adding the two strings together correctly.
Please help
Cheers
Helen

pod::text::overstrike
Pod::Text::Overstrike(3pm) Perl Programmers Reference Guide Pod::Text::Overstrike(3pm) NAME
Pod::Text::Overstrike - Convert POD data to formatted overstrike text SYNOPSIS
use Pod::Text::Overstrike; my $parser = Pod::Text::Overstrike->new (sentence => 0, width => 78); # Read POD from STDIN and write to STDOUT. $parser->parse_from_filehandle; # Read POD from file.pod and write to file.txt. $parser->parse_from_file ('file.pod', 'file.txt'); DESCRIPTION
Pod::Text::Overstrike is a simple subclass of Pod::Text that highlights output text using overstrike sequences, in a manner similar to nroff. Characters in bold text are overstruck (character, backspace, character) and characters in underlined text are converted to over- struck underscores (underscore, backspace, character). This format was originally designed for hardcopy terminals and/or lineprinters, yet is readable on softcopy (CRT) terminals. Overstruck text is best viewed by page-at-a-time programs that take advantage of the terminal's stand-out and underline capabilities, such as the less program on Unix. Apart from the overstrike, it in all ways functions like Pod::Text. See Pod::Text for details and available options. BUGS
Currently, the outermost formatting instruction wins, so for example underlined text inside a region of bold text is displayed as simply bold. There may be some better approach possible. SEE ALSO
Pod::Text, Pod::Parser The current version of this module is always available from its web site at <http://www.eyrie.org/~eagle/software/podlators/>. It is also part of the Perl core distribution as of 5.6.0. AUTHOR
