Replace New Lines in Unix (Beginner)
Hi, I was wondering if anyone could help me with this problem. I have a file that looks like this, for example:
John Smith Ann Smith I want to get the text to be in 2 columns, : John Smith Ann Smith Would I be best using SED to replace the new line with a space? (How would I do this?) Or would it be better to use pr? Sorry for the mundane-ness of this Q but I've just starting on Unix! Many Thanks, Jessica

ignore that stupid 'cat' Quote:
perl -e '{while(<STDIN>) { chomp; $jm.=" $_"; if(($.%2)==0) { $jm=~s/\s+//; print "$jm\n"; $jm=""; } } }' ~/tstfile should also work (not tested) nota: this does the same sed '{N;s/\n//;}' filename
