sed delimiter
 

Hi Guys,

I wonder what is the sed option equivalent to cut delimiter like example below

HOSTNAME=XXX

I want only XXX ,so for cut command I use.

echo "HOSTNAME=XXX" |cut -d "=" -f 2

How can I use sed in this way ?

Thank you.

I'm not sure why you'd want sed there, but

HTH

Thank you chrism01!

This of course relies on there not being a chance there is another equals sign in the hostname.

Thank you very much gentlemen . The reason is I'm newbie on sed and trying to use it as a powerful stream editor.

And could you please explain a bit more on the code above. I know that "s/" is search but I don't get this "[^=]*=" .

Thank you.

Hi kankan55

you can understand the general syntax for sed command

sed 's/$unwanted/$wanted/' $file

Here s = substitute
$unwanted is what you dont require or want to replace.
$wanted is what you need insted of unwanted.
$file is your input file or u can have a pipe statement.

[^=]*= - zero or more (*) lots of not the equal sign ([^=]) followed by a single equal sign (=)
