This question already has an answer here:
This open-man-page-and-search-for-string-in-a-single-command question half covers what I'm trying to do:
Instead of doing man chmod and then /a+x to jump to the first section in the chmod man page that mentions a+x, I would like to know if there is a way to open the man page to a specific search string, similar to how you can do vi +string filename.txt in vi(m).
The chosen answer was
man foobar | less +/searched_string
However, when I try
man tmux | less +/^format
Less launches but returns
Pattern not found (press RETURN)
Why is the pattern not being found?
