Hi
I want to know how I can search something like +o in a man page?
When I type /+o in man page,it says nothing to repeat (press ENTER).

please guide me
thank you

You have the slash the wrong way. Try this:

Note that "man" doesn't provide the search feature, the display program assigned to open them does. This is usually less, so have a look at its documentation.

The slash is the search command. This is what the OP should enter:

Also, I thought that less uses basic regular expressions, which don't interpret "+" as special unless it's preceeded by a backslash. The less man page doesn't say what it uses, though:

please try this :
man 1p set

then try to search +o
\+o doesn't work

how I can less man pages? you mean something like this :
man 1p set | less
In this case I can't search for +o again.

(Note : I know it is not critical,but I am eager to learn )

[QUOTE=zeusys;4459055]please try this :
man 1p set

You did first use the "/" command to start searching, right?

man uses less.

You (likely) don't need to do anything. You're already using it.

As I tried to explain before, the man command itself doesn't display the page; it just grabs the page you want from the database and formats it. Then it automatically outputs the results to the default pager, unless you override it. This should be less, unless you've changed it somewhere.

If I'm reading it correctly, the man command looks for the following to determine which pager to use, in order.

the -P option
an equivalent setting in the $MANOPT environment variable
the $MANPAGER environment variable
the $PAGER environment variable

Use one of these if you want to override the default.

Read the man man page for more.
Also read the man page of the pager it's using for how to use its search options.
