I have a bunch of files with filenames like Matroid (bifrons's conflicted copy 2019-11-19).scala due to problems of synchronization. I want to find this files to remove or manually correct the problems (merge the two versions of the file). I tried the command below:
$ find . -iname '*conflicted*'
But it returns nothing! Nada!
I am guessing this is because the word conflicted occurs inside parentheses, but this is just a conjecture. Anyway, why my command do not find the files? How can I find them?
Thanks.
Actually the problem had nothing to do with parentheses at all. It as a (silly) mistake of mine. The directory containing the files with the *conflicted* filename was actually a link and find does not follow links by default. After informing the option -L it worked perfectly.

Please, open File 1 to access the problem. If I type it here some important characters that I believe to be what's causing the drama won't show on the post. Thank you!
I basically created a file that I can't get rid of.

Space, <, and > are all treated specially by your shell.
Because of that, you'll need to quote the name. Try this:
rm 'index.html <RET>'
In cases where you can't figure out how to quote/escape the filename appropriately, a convenient approach is:
rm -i index.html*
You will be prompted (because of the -i option) to delete each filename matching the specified glob pattern, one at a time. Simply answer y to the ones you want to delete.
Quoting the arguments correctly is safest (it avoids any possibility of accidentally deleting something you didn't mean to delete), so I recommend always doing so when you can; but if you've managed to generate a really garbled filename (Unix places very few constraints upon filenames) then this method can be very useful.
there is an --exclude option but that to exclude the directories/files. I work on a big project and want to only include the directories that has source code and not build stuff.
How to do that? What should I include in my .ctags file?
I use:
find FILES | ctags -L -
where FILES is the appropriate arguments to make find return only the files I want to index.
Exuberant Ctags (5.8) is now old and unmaintained, though. It still works for me, so I've not switched; but the last time I checked "Universal Ctags" appeared to be the way forwards, so I would suggest starting there:
https://ctags.io
https://github.com/universal-ctags/ctags
n.b. I experienced a curious bug with Exuberant Ctags 5.8 whereby find . resulted in some corrupted tag entries, but find * did not; so you might want to use the latter if using this approach. I didn't need to index any dot files at the root level, so I'm not sure offhand what happens for .* -- I don't think I tried it. Absolute paths were also fine, but then the TAGS file isn't portable. Potentially not an issue in the newer fork.
How do I set up cscope in Emacs when my source code lives in multiple directories?
Say I have several paths for my C++ project:
/path/to/my/code (and subdirectories)
/path/to/other/code (and subdirectories)
/path/to/static/linking/include/files (and subdirectories)
/path/to/static/linking/lib/files' (and subdirectories)
I would like to use xcscope to navigate/look up symbols in my code and the library that I am linking to.
The instructions for xcscope.el say that I should first run C-c s (Cscope->Create list and index) at /path/to/my/code, but I am then confused about how I to have the other paths indexed by cscope.
The documentation says I should go to the other directories and run cscope -b, but what I am supposed to do after that?
I looked at the cscope.files file that C-c s built. I think I am supposed to add my other paths to this file, but this file includes a list of source code files (not directories).
Do I have to manually edit cscope.files to add every single file that I want to index that is outside of my project's root directory?
The documentation is confusing.
I got one sol'n from http://cscope.sourceforge.net/large_projects.html. Still confusing.
cscope.files is aptly named. It is NOT directories. It is files, only files. Which is as daunting as it sounds. What if you have hundreds of files. Then you have to write hundreds of lines, one per file, into cscope.files. No joke.
Automate it with some scripting. E.g., on linux, use bash scripts and redirection (>,>>,|) operators to select and filter files from any and all directories into that cscope.files.
What about the directory where cscope.files resides? IF you don't include those files, it'll only find them when you open your project (in emacs, but probably applicable to any IDE) in that source directory. So, include them, too, for easy opening of your project from anywhere.
The option "recursive/-R" seems obvious to send to cscope-indexer. Nope, not with many root directories. Does nothing (probably could do something with scripts or elisp or who knows). Just feed those files, absolute path, into cscope.files. And you might have to make sure you have only one cscope.files per project. Don't split them up relative to each diretory. Or maybe you can, something to look into.
Remember, include the /path/to/each/file/ before the file if you want cscope.files to point to it from anywhere. cscope isn't "smart", it's dumb, it just takes directions for where to look and it won't know where to look for "filename", without knowing where it is. You're just asking it to call locate filename, which it can't do anyway, when you give it a lonely filename without a dir path outside of the directory that a particular cscope.files resides.
I hope there's a way to use xcscope inside emacs, just adding directories which it will catalog and index, as the xcscope docs and emacs menu suggest. But I didn't succeed in making it work that way.
Wouldn't a soft link (ln -s) work? Worked for me.
I have an application (Templify) that creates a templatized directory structure, but it seems to not be able to rename the "__NAME__" with what I've identified as the target.
This is fine if I can find a clean way to rename all files & directories with my replacement text.
I found a rename.pl method that renames files, and I found some code that removes underscores in file names and replaces it with spaces... but when I modify the code to put in my search terms, it never seems to work.
So, basically, I need to replace "__NAME__" with something like "Project-Name".
I'm happy to modify the search strings for each future reuse, but I'd love to figure out how to create a file to which I can pass ARGS.
I'm on XP and can use cygwin (cygwin doesn't seem to have 'rename' which makes it hard to locate linux-type solutions with using the function called 'rename'....)
I did find this which is easy to use for files in the current directory, but I don't know enough to tell it to recurse into sub-directories.
Any help would be great.
Thanks,
Scott
From cygwin:
find /cygdrive/c/mytree -type f | perl -ne 'rename $_, $1/Project-Name if m[^(.*)/__NAME__$]'
Or using python:
import os
for root, dirs, files in os.walk("C:\\mytree"):
for filename in files:
if filename == "__NAME__":
os.rename(os.path.join(root, filename), os.path.join(root, "Project-Name"))
I've looked through several similar questions, but either I didn't understand their answer or my question is different than theirs. So, I have a project contains many subdirecties and different type of files. I would like to search a function name among those .C files only.
Some information on the web suggest to use "Esc x dired-do-query-replace-regexp". However, this will search not just C files, but also other file like .elf which isn't helpfule in my case. Other people sugget to use TAG function, but it will require me to type "etags *.c" for every subdirectory which is also impossible.
How should I do this while working on those large scale software project?
Thanks

Use ack-grep on linux
ack-grep "keyword" -G *.c
My favorite: igrep-find, found in the package igrep.el. Usage is:
M-x igrep-find some_thing RET *.C
There's the built in grep-find, docs here, but I find it awkward to use.
For a more general answer, see this similar question: Using Emacs For Big Big Projects.
if you're on linux, you can use grep to find files with a certain text in them. you would then do this outside of emacs, in your shell/command prompt. here's a nice syntax:
grep --color=auto --include=*.c -iRnH 'string to search for' /dir/to/search/
the directory to search can be specified relative, so if you're in the directory you want to use as the root directory for your recursive search, you can just skip the whole directory address and specify a single dot.
grep --color=auto --include=*.c -iRnH 'string to search for' .
the part --color=auto makes some text highlighted. --include=*.c is the part that specifies what files to search. in this case, only files with the c-extension. the flag i makes stuff case insensitive, the flag R makes the search recursive, the flag n adds the line number to the report, and the flag H adds the file path to the report.
To breed find and grep there is find-grep function, there you can change the invocation string to find . -name *.c etc. Make it a function, if You like. Then You use eg. C-x` et al. to navigate the results.
To search among the files in one directory i use lgrep, it prompts you in which files to search.
You can use cscope and xcscope.el : http://www.emacswiki.org/emacs/CScopeAndEmacs
Try with dired: place the cursor on the directory name to search, type A and in the minibuffer the text to find.
