Hi all,
Why does '$$' means an empty line in agrep -d '$$'. I did not know that '$$' can be seen as an empty line in regular expression. So did I miss something here ?

COLCRT(1) General Commands Manual COLCRT(1)
NAME
colcrt - filter nroff output for CRT previewing
SYNOPSIS
colcrt [ - ] [ -2 ] [ file ... ]
DESCRIPTION
Colcrt provides virtual half-line and reverse line feed sequences for terminals without such capability, and on which overstriking is
destructive. Half-line characters and underlining (changed to dashing `-') are placed on new lines in between the normal output lines.
The optional - suppresses all underlining. It is especially useful for previewing allboxed tables from tbl(1).
The option -2 causes all half-lines to be printed, effectively double spacing the output. Normally, a minimal space output format is used
which will suppress empty lines. The program never suppresses two consecutive empty lines, however. The -2 option is useful for sending
output to the line printer when the output contains superscripts and subscripts which would otherwise be invisible.
A typical use of colcrt would be
tbl exum2.n | nroff -ms | colcrt - | more
SEE ALSO
nroff/troff(1), col(1), more(1), ul(1)
BUGS
Should fold underlines onto blanks even with the `-' option so that a true underline character would show; if we did this, however, colcrt
wouldn't get rid of cu'd underlining completely.
Can't back up more than 102 lines.
General overstriking is lost; as a special case `|' overstruck with `-' or underline becomes `+'.
Lines are trimmed to 132 characters.
Some provision should be made for processing superscripts and subscripts in documents which are already double-spaced.
