Power Replacing Carriage returns without loosing EOL
Hello, I have read a few threads on this subject and tried a few things out, but still come up short.

There was one good example, then the last reply was something to the effect of 'Use Sed' & 'Read a book'...

Well I read a bunch of online tutorials on sed, awk, tr, but still can't get the right results.

input file>

1234|hello there buddy|8beers|2008-01-01
1234|this is a nice party, don't you think?|2champaigns|2008-01-01
1234|there are two things:
thing 1 & thing2|36shots|2008-01-01

desired output>
1234|hello there buddy|8beers|2008-01-01
1234|this is a nice party, don't you think?|2champaigns|2008-01-01
1234|there are two things: thing1 & thing2|36shots|2008-01-01

The closest I could get was with this command->

nawk '{ if ( $0 ~ /1234/ && NR > 1 ) { printf "\n"; } printf $0; } END { printf "\n"; }' party.txt > dump.txt

But after line 460664 I received an error:
awk: There are not enough parameters in printf statement ...

The only thing that looks different about that line is there is an ampersand '&' in one of the fields.

I tailed the rest of the file into the the nawk and it puked after another 1600 lines. I tried a couple more times and it still keeps running out of steam before the millionth row.

The other way I tried was ghetto style:
tr -d '\n' to remove all the carriage returns, then
sed s/2008-01-01/2008-01-01\n/g <party.txt> dump.txt

but sed pukes with a sed: Memory allocation failed after about a minute.

Ideally, I need a one liner...
Any suggestions?

Thanks.

getunimap

GETUNIMAP(8)							       Linux							      GETUNIMAP(8)

NAME

       getunimap - dump the unicode map for the current console to stdout

SYNOPSIS

       getunimap [ -s ] [ -C console ]

DESCRIPTION

       The getunimap program is old and obsolete. It is now part of setfont (1).

       The getunimap program outputs the unicode map (also called a "Screen Font Map") for the current console to standard output.

       The  -C	option may be used with Linux 2.6.1 and later to get the map for a console different from the current one. Its argument is a path-
       name.

       The output of getunimap is of the form

		   0xAA U+1234 # comment

       where 0xAA is the font character code and U+1234 is a unicode character, that if displayed, will be displayed using glyph 0xAA in the font.
       Many unicode characters may be mapped to the same glyph.
       the Hash symbol # is used as a comment delimiter; characters after a hash sign (to the end of the line) are comments.

       The -s option will sort and merge elements, sorting on font character.  Hence, it will produce output of the form:

		   0x22 U+1234 U+5678 U+3456
		   0x23 U+0023

	    etc., listing the multiple unicode characters that map to a font glyph.

       The output of getunimap is of the form accepted by setfont and psfaddtable

SEE ALSO

       psfaddtable(1), setfont(1).
