You can save portions of the string with \(.*\) and recall it back with \1, \2, \3 etc.
Here we save that portion after ".*up " and before ",.*user.*" and recall the portion with \1.

Try something like this:
Code:
uptime | sed 's/.*up \(.*\),.*user.*/\1/' | awk -F: '{print "uptime: " $1" h "$2" m"}'

lessecho

LESSECHO(1)						      General Commands Manual						       LESSECHO(1)

NAME

       lessecho - expand metacharacters, such as * and ?, in filenames on Unix systems.

SYNOPSIS

       lessecho [-ox] [-cx] [-pn] [-dn] [-a] file ...

DESCRIPTION

       This  manual  page  documents briefly the lessecho command.  This manual page was written for the Debian GNU/Linux distribution because the
       original program does not have a manual page.

       lessecho is a program that simply echos its filename arguments on standard output. But  any  argument  containing  spaces  is  enclosed	in
       quotes.

OPTIONS

       A summary of options are included below.

       -ox    Specifies "x" to be the open quote character.

       -cx    Specifies "x" to be the close quote character.

       -pn    Specifies "n" to be the open quote character, as an integer.

       -dn    Specifies "n" to be the close quote character, as an integer.

       -a     Specifies that all arguments are to be quoted. The default is that only arguments containing spaces are quoted.

AUTHOR

       This manual page was written by Thomas Schoepf <schoepf@debian.org>, for the Debian GNU/Linux system (but may be used by others).
