the problem with grep is it has a line limit (2048) lines. If you file has more lines than that it will stop when it gets there. I just learned a cool way to do the same thing using awk. I don’t think it has the same limitations.

awk ‘{ if (length($0) > 0){ print $0 }}’ inputfilename >> outputfilename

This will search inputfilename and as long as the line has one character on it it will be sent to the outputfilename eliminating blank lines in outputfilename.

add
| grep -v “^$”
to the end of the command chain to eliminate blank lines.
