egrep regex
Hi,

I have a file with some words divided into syllables by the character "|" (pipe).
For example zu|ri|ghe|se.I would like a regex that matches all the words that are not divided in syllables.All the word that have no "|" pipe character.I have thought at

$echo "zu|ri|ghe|se" | grep '[^|]'

But it doesn't work.Why?Thank you.

Do you mean something like

Code:
echo "zu|ri|ghe|se" | awk -v RS="|" '{print}'

The question isn't so clear (you said you wanted to find them, but not what you wanted to do with them).

egrep regex
I would like to put into a file the words that haven't the pipe character.
for example

gru|vie|ra
gru|ye|re
gruzzo
gruzzolo
gua|ca|mo|le
guac|co
gua|co

into the file will be putted

gruzzo
gruzzolo
because there is no pipe character.Thank you.
