Quick one. I use this command to insert a line. So if there is a space in the pattern between to entries in the text or file it prints the content on the new line/ . It works fine, however sometime I encounter 2 spaces or 3 spaces instead of one that i'm looking for in the pattern so I get an additional blank lines.

sed "s/ /\n/g"

I want to print a new line only the sed find something in the pattern . How should I use the sed command to treat 1 space or double or triple spaces as one substitute?

Thanks

You need a quantifier:

sed "s/  */\n/g"

or

sed 's/ \+/\n/g'

or

sed -r 's/ +/\n/g'

or

sed 's/ \{1,\}/\n/g'

or

sed -r 's/ {1,}/\n/g'

You could also use tr:

tr -s ' ' '\n'
