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_stringHowever, when I tryman tmux | less +/^formatLess launches but returnsPattern not found  (press RETURN)Why is the pattern not being found?OS - Ubuntu 15.10% less --versionless 458 (GNU regular expressions)Copyright (C) 1984-2012 Mark Nudelman
Why is this command to open man page and perform search not working?
