RE: SED on AS400 -- MIDRANGE-L

Correct!!  I forgot about the '*' means 0 or MORE!!!!

sed -e'/^ *$/d' -e'/^$/d'

line1has2dashes_line2has2spaces_line3has2dashes.txt    
  --

sed '/^$/d' line1has2dashes_line2has2spaces_line3has2dashes.txt

sed -e'/^ *$/d' -e'/^$/d'

sed '/^ *$/d' line1has2dashes_line2hasnewlineonly_line3has2dashes.txt


Wouldn't the expression from that article do exactly that?  Since * 
matches ZERO or more occurrences (as opposed to one or more), wouldn't the 
sed expression from the IT Jungle article match an empty line as well as 
one that contains blanks?

Also if you want to additionally remove lines that seem blank but

don't contain "blanks", just a "\n", this should work:

Subject: SED on AS400


Does anyone have experience in working with the SED pgm in qshell?  If
possible, does anyone have any syntax of how it could be used on an

AS400

command line?

We have a lot of stmf's from business partners that contain blanks and
instead of writing pgm's to remove the blank lines we'd like to use the

SED

pgm, if possible.
