less -S

-S will disable soft line breaks within less, allowing horizontal scrolling.

Tailing Files

Use less +F instead of tail -f. It works the same, but supports interrupting the stream with SIGINT to e.g. search around, and then can resume tailing by hitting F again.

Doing so will even then highlight the search pattern in the future text.

less +command

Passing +command will run the given command each time a new file is opened by less.

Filtering Lines

&pattern will filter lines only matching the given pattern.

Opening EDITOR

Hitting v will open the file in an editor.
