In Dired imagine you have the following directory.
| - src
| - | - text_input.rs
How do you create a file in the src directory named text.rs (in emacs)? How would you rename a file in the same directory to text.rs?
If you try to create a file through 'find file' or rename a file colocated with text_input you can have an issue.
If the file you are trying to create is text.rs, the '.' will be interpreted as a regex "any character" selector. You will not be able to create as find will resolve to text_input. Rename similarly fails, however I don't understand why.
If this is unanswered and you find yourself here I have a gnarly hack. Rename text_input.rs to a placeholder name, rename or create text.rs, then return the name to the text_input.rs.
Edit: Its been brought to my attention this isn't because of vanilla emacs, but because of the combination of tools bundled within doom emacs. Given this I am moving to escalate this within proper channels.

When trying to open a file with text editor VIM, I am unable to open the file unless VIM (shortcut) is in my current working directory. As an example, I am able to write start firefox to open a firefox window. However, start vim C:\filepath\filename.txt does not work unless a vim shortcut is in my current directory. How do I get around this?
Also, is there a way to have a program execute a file in the current working directory without having to reference the entire file path? For example instead of Start-Process vim C:\Users\User\Desktop\File\file.txt is there an available path shortcut like Start-Process vim ~\file.txt with ~ representing the current working directory?
The OS need to determine the full path of the exe, no matter what.
There's 2 ways that it will happen.
You're calling the executable from it's working directory
The executable location is in the Windows environment variable.
You can view the PATH variable content through this simple statement
$env:Path -split ';' | sort
You sill see that the Firefox path is listed there, but not the one from VIM.
That's why the former can be started by it's executable name and the latter require the full path.
You need to add VIM directory to your PATH variable if you want to be able to call it just by typing vim
Otherwise, if you have restricted access or don't want to edit that variable, you can also set a $vim variable, then invoke it whenever you want to call the executable.
Regarding the second part of your question
Powershell use the dot as a reference to the current directory .\file.txt.
You can also just specify the filename without anything else file.txt.
Both backslash \ & slash / work for filepath so .\file.txt and ./file.txt are both valid ways to reference the file.
Use ..\ to reference the parent directory (e.g. ..\file.txt)
$Vim = "c:\Path\To\Vim.exe"
& $vim "file.txt"
& $vim ".\file.txt"
#Forward slash also work for paths
& $vim "./file.txt"
I have 200,000 files I want to send to different folders based on key words in the file name
in English if a file name has (shtf or prepper or prepping or survival) in the name send(move) it to folder shtf
if a file has (cookbook or gluten or recipe) move to food folder
*cookbook* *GLUTEN* *RECIPE*
example
(file name)
more shtf tips.epub move to folder shtf
ifshtfbeready.epub move to folder shtf
oldworldcookbook.epub move to folder food
i'm old retired ibmer small basic sas dos commands or ????
Here is a bash command, you may be able to adapt it into dos etc. I'm posting this because others may it useful as well.
find . | grep -E "(cookbook|gluten|recipe)" | while read name; do mv $name directory; done;
Where directory is the name of the directory you want to move the file. You can replace . with whatever starting directory you want, of course.
You can use wildcard in the source filename list and use a directory as the target to move multiple files with one command.
move c:\dir1\*cookbook*.* c:\food
move c:\dir1\*gluten*.* c:\food
Okay so I want to know how I would go about doing this, using grep to locate .txt files named "cocacola1", "cocacola2", "cocacola3" & then copying them to another directory. So searching for files named "cocacola" &/even if it contains other characters within the file name to then copy them to another directory/location.
You can just use unix find. Assuming the files you're searching for are in 'source' and you want to copy to 'destination':
find source -name '*cocacola*' -exec cp {} destination \;
I put the wildcard '*' before and after cocacola since you said other characters might exist in the file name.
This should work on my CentOS 6.6 but somehow the file name is not changed. What am I missing here?
rename -f 's/silly//' sillytest.zi
This should rename sillytest.zi to test.zi but the name is not changed. Of course I can use mv command but I want to apply to many files and patterns.
There are two different rename utilities commonly used on GNU/Linux systems.
util-linux version
On Red Hat-based systems (such as CentOS), rename is a compiled executable provided by the util-linux package. It’s a simple program with very simple usage (from the relevant man page):
rename from to file...
rename will rename the specified files by replacing the first occurrence of from in their name by to.
Newer versions also support a useful -v, --verbose option.
NB: If a file already exists whose name coincides with the new name of the file being renamed, then this rename command will silently (without warning) over-write the pre-existing file.
Example
Fix the extension of HTML files so that all .htm files have a four-letter .html suffix:
rename .htm .html *.htm
Example from question
To rename sillytest.zi to test.zi, replace silly with an empty string:
rename silly '' sillytest.zi
Perl version
On Debian-based systems ,rename is a Perl script which is much more capable
as you get the benefit of Perl’s rich set of regular expressions.
Its usage is (from its man page):
rename [ -v ] [ -n ] [ -f ] perlexpr [ files ]
rename renames the filenames supplied according to the rule specified as the first argument.
This rename command also includes a -v, --verbose option. Equally useful is its -n, --no-act which can be used as a dry-run to see which files would be renamed. Also, it won’t over-write pre-existing files unless the -f, --force option is used.
Example
Fix the extension of HTML files:
rename s/\.htm$/.html/ *.htm
example
There is a file "sample.rar".
Folder structure is: "rising\dawn\ and here there are many (folders1, folders2 and file1, file2)" in this archive.
i have used following command
7z.exe x "sample.rar" "rising\dawn\*" -oi:\delete
The result is:
all files and folders in "rising\dawn\" are extracted to "i:\delete" folder but the empty parent folders "rising\dawn\" are also created in destination folder.
e.g. destination looks:
i:\delete\rising\dawn\folder1\file1.bmp
i:\delete\rising\dawn\folder2\subfolder
i:\delete\rising\dawn\file1.txt
i:\delete\rising\dawn\file2.txt
i don't want "rising\dawn\" empty folders to be created but the folder structure there onwards must be as is in the archive.
i want the result:
i:\delete\folder1\file1.bmp
i:\delete\folder2\subfolder
i:\delete\file1.txt
i:\delete\file2.txt
at last i found a way out solution. thanks to the winrar support. i have accepted it as an answer below.

Finally this gave me the result.
Thanks to winrar support.
rar x -ep1 sample.rar rising\dawn\* d:\e\delete\
i have tried other answers given here, this is the only correct answer.

You can extract the archive normally and
1) move the lower level folder/files to where you would like it, then
2) remove the extra top level archive folders.
Code to do so will depend on the exact task.
Using e command instead of x and add -r option works well.
Like this:
7z.exe e -r "sample.rar" "rising\dawn\*" -oi:\delete
My executable version is "7-Zip [64] 9.20 2010-11-18",
And the platform is Windows 8.1.
This command line eliminates unnecessary parent folders and preserves the hierarchy of folders.
You need to use the e command rather than the x command:
7z.exe e "sample.rar" "scholar\update\*" -oi:\delete
Using e instead of x means 7zip will extract all matching files into the same folder (as specified via the -so switch, or the current directory if this isn't specified) rather than preserving the folder structure from inside the archive.
