Grep for String and open at the corresponding line

Question

I'm having several occurrences of a specific string over several files in several lines obtained with grep.

$ grep -rn --include="*.cpp" mystring
lib/mlib/actionbuttonrule.cpp:300:  mystring Foobar...
lib/mlib/actionbuttonrule.cpp:314:  other mystring
lib/mlib/item.cpp:3025:             /* mystring**/
lib/mlib/item.cpp:3082:             mystring Foobar...
lib/mlib/item.cpp:3095:             Foo mystring bar

I'd like to open these files sequencially on the corresponding lines. I tried to do it with vim, but so far no success when it comes to open the line. Mustn't be vim or grep, but I'd assume there must be some kind of functionality out there...

Answer 1

Here is another way to do

$ grep -rn --include="*.cpp" mystring > op
$ vim op

Then use gF and to come back to file op, use Ctrl + 6

Answer 2

You can load your grep output in Vim's quickfix list with:

$ vim -q <(grep -rn --include="*.cpp" mystring)

Go to the next occurence with :cn and to the previous occurrence with :cp.

See :help -q and :help quickfix.

A trick to use vim as a pager is to pass it a hyphen character. This causes it to read from STDIN instead of from file

grep -rn --include="*.cpp" mystring | vim -
