As usual, there are several ways to do this. The easiest is to
dispense with the temporary file and invoke your grep command from
within vim:
:grep if /etc/profile
The results go into the quickfix list just as they do when you
execute ":make". See
:help grep
Vim takes care of supplying the right arguments to grep and
constructing the command line so that you don't need to supply the
-H or -n options yourself.
If you already have the temporary file loaded into a buffer in vim,
you can move the cursor to the start of any of the lines and type
gF
to jump to that file and line number.
^WF
does the same but opens the file in a new window. See
:help gF
:help CTRL-W_F
A third way, that uses both the temporary file and the quickfix
list, is to open your temporary file like this:
gvim --cmd 'let &efm=&gfm' -q /tmp/grep_output.txt
See
:help -q
Since the -q option uses the 'errorformat' ('efm') to parse the
error file, and since 'errorformat' matches the output of a
compiler, not of grep, you need to assign the value of
'grepformat' ('gfm') to 'errorformat' before opening an error file
containing the output of a grep command.
For other ways to get data into the quickfix list, see
:help :cf
:help :cb
As for jumping to a line by double clicking on the file name and
line number, see
:help double-click
for an example of mapping a double click to the operation of your
choice.
