Nice, didn't think of using ^$ like that, had to stick it in double quotes to get it work on sco by the way.

Just complementing ...

In the awk command, you may subtitute the $1 for $0 if yoy have space between words, because $0 references the entire line and $1 only the first column.

awk '{if ( $0 != "") print $0}' < arq.in > arq.out

arq.in:

aaa aaa aaa aaa

bbb bbb bbb bbb

ccc ccc ccc ccc

arq.out:

aaa aaa aaa
bbb bbb bbb
ccc ccc ccc
