Question

I have a large log file from which I need to extract file names.

The file looks like this:

/path/to/loremIpsumDolor.sit /more/text/here/notAlways/theSame/here
/path/to/anotherFile.ext /more/text/here/differentText/here
.... about 10 million times

I need to extract the file names like this:

loremIpsumDolor.sit
anotherFile.ext

I figure my first strategy is to find/replace all /path/to/ with ”. But I’m stuck how to remove all characters after the space.

Can you help?

Answer 1

sed 's/ .*//' file

It doesn’t take any more. The transformed output appears on standard output, of course.
