If you like you have PDF copies of your manual pages, here is a function I added to my
.bash_profile file to create a PDF of each BSD command I'd check the manual page for:
[[ ! -d $docDir ]] && mkdir -p "$docDir"
if [[ ! -f $docDir/$1.pdf ]]; then
man -t "$1" | pstopdf -i -o "$docDir/$1.pdf"
So, in Terminal, typing e.g.
manp bash instead of
man bash a PDF gets created, if it hasn't already been, and then opened by the app registered to handle PDF documents. The default is Preview, however on my system it's set to use Skim, as its search functionality is better then Preview and as a matter of fact will find the search string when Preview just will not.
Note that the first time the function is used it will enumerate some fonts in the output in Terminal, however this is a one time enumeration of the fonts.
The nice thing about PDF copies is it maintains formatting, i.e. bold font and italics, etc.
As a side note, typing just the command name in Terminal and then right-click on it and select Open man Page, displays it in a fully scrollable and searchable Terminal window, which is much better then typing e.g.
