Remove spaces from columns
I have a file with only one field something like this :
213.45

220.65

240.47


345.67

320.45

I want to remove all spaces in between. Is there any unix command for that ?Thanks in advance..

If you mean blank lines:

Code:
grep . filename

or without external commands:

Code:
printf "%s\n" $(<filename)
