Question

Using sed, if there is a space character on a line in a file, I need to print the output with the space character and anything after it removed. Code example:

sed "s/"something here I think"//g' file

So, let’s say a file says this on a line:

 Chuck Norris is the man

I just need it to print:

 Chuck

Multiple lines applicable too:

Chuck Norris is the man
So is Arnold

Replaced:

Chuck
So

Answer 1

This should do it for you:

sed 's/ .*//g'  file

To remove from the beginning of the line to the first space, use this:

sed 's/^[^ ]* //g'
