Question

I want to debug a process, hence I attached strace to the process and redirected the output to a file and then performed the operation. During the process it has created a lot of processes. So here is what I want to do, I want to select all the system calls executed by a process. To do that I used grep command with pattern as pid:

:grep pid %

It shows the result but I am not able to traverse through the result, it promts

Press ENTER or type command to continue

and returns to the file. What I would like to do is store the result in a buffer and then have a look into it and if required save it into a file or else discard it and return to the original file. Is there a way to do this with out exiting from the vim editor? Thanks in advance.

I would like to search with the result and store that in a buffer.

Answer 1

You can go to older searches, and back easily:

:copen
:colder " goes to older
:cnewer " newer

You can have another search using lvimgrep (uses location window):

:lopen
:lnext
etc...

It also has history:

:lolder
:lnewer

You can read into any buffer:

:r!grep bla **/*.cs

Finally, any command that gives output, can be redirected with the redir command:

:redir >> file
:grep bla **/*.cs
:redir END

See :he redir for the many ways to use it (redirect into registers or variables).
