3. Search unopened files (grep) for a string or re.
How do you do this with emacs?
I find a menagerie of greppish commands -- rgrep, lgrep, grep-find etc
To grep for a pattern in the directory of the active buffer:
M-x grep
Run grep (like this): grep -nH -e
Complete the grep command:
Run grep (like this): grep -nH -e class *.py
and hit ENTER. Feel free to modify the command from grep to egrep, for
example. I often replace -e with -i.
To grep for a pattern in any subdirectory:
M-x grep
Run grep (like this): grep -nH -r assert .
or:
M-x grep-find
Run find (like this): find . -type f -exec grep -nH -e assert {} +
Again, you can modify the command freely:
M-x grep-find
Run find (like this): find . -name '*.py' -exec grep -nH -e assert {} +
Thank you for the answer. I once had things like this memorized, but now
I prefer Idle's dialog, with selected text (if any) and the full path of
the current directory (+/.py) pre-inserted as target and search
directory, and options as radiobuttons (remembered from my last search) ...
You will get a list of hits in a new buffer. You can use the C-x `
command to traverse them in order, but there are many other ways.
and a scrollable window for results ;-).
