>Description:
%sed `perl -e 'print "s/"; print "x" x 2044; print "//g"'` test.dat
%sed `perl -e 'print "s/"; print "x" x 2043; print "/y/g"'` test.dat
%sed `perl -e 'print "s/"; print "x" x 2042; print "/yy/g"'` test.dat
The commands above all give no output, regardless of the input file. Any other total count of x's and y's in the substitute pattern will print the file test.dat without modification, (up to 2046, at which point sed appears to begin truncating the input):
%sed `perl -e 'print "s/"; print "x" x 2046; print "//g"'` test.dat
sed: 1: "s/xxxxxxxxxxxxxxxxxxxxx ...": unterminated substitute pattern
It's a little strange that the pattern seems to work for 2045 characters, but not 2044 or 2046.
