I want to delete all subdirectories and files from a directory, but not the directory itself. For examnple, if I pass "Sample" directory in a variable, and "Sample" directory contains three subdirectories and 3 files, I want to delete all that 3 directories and 3 files. In practice, the "Sample" directory can contain many subdirectories and files.
ETA: This is actually in perlfaq5: How do I delete a directory tree?
Use File::Path, core module.
perl -MFile::Path=remove_tree -we
'remove_tree("Sample",{keep_root=>1}) or die $!'
The keep_root option will cause remove_tree to keep the top directory:
keep_root => $bool
When set to a true value, will cause all files and subdirectories to
be removed, except the initially specified directories. This comes in
handy when cleaning out an application's scratch directory.

The Goal:
How to use .gitignore to exclude all folders & files except PowerShell $Profile?
The answer should help expand the current exception file list to more files in other subfolders. If possible, reduce wildcards to minimum, and use as specific as possible (full/fuller file path). Why? For instance, Book1.xlsx may exist in multiple subfolders but I want to be able to choose only the specific desired subfolders.
Thanks in advance!
Current status:
On Windows 10 (not Linux Distros):
git init initiated on top level directory C:\. [Please don't suggest to start from other subfolders. Just remain with C:\, as I will include more files to the exception list]
C:\.gitignore containing the below:
# Ignore All
/*
# Exception List [eg. PowerShell's $Profile (please use FULL/FULLER FILE PATH, if possible)]
!.gitignore
!Microsoft.PowerShell_profile.ps1
!Users/John/Documents/WindowsPowerShell/Microsoft.PowerShell_profile.ps1
!Users\John\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1
!C:/Users/John/Documents/WindowsPowerShell/Microsoft.PowerShell_profile.ps1
!C:\Users\John\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1
With the above codes, git status successfully returned only .gitignore as 1 untracked file. Microsoft.PowerShell_profile.ps1 remained missing from untrack listing.
I've tried alternative ways (wildcard, partial subfolder name with pattern, etc) but all failed to return the fuller file path PowerShell $Profile.
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.
Imagine the following structure:
/a/1.txt
/a/2.txt
/a/.keep
/a/b/1.txt
/a/b/2.txt
/a/b/3.txt
/a/b/.keep
/a/b/c/1.txt
/a/b/c/2.txt
/a/b/c/3.txt
/a/b/c/4.txt
/a/b/c/.keep
/d/test.txt
/d/work.txt
I want to ignore all files in a directory except .keep files to obtain the following results:
/a/.keep
/a/b/.keep
/a/b/c/.keep
/d/test.txt
/d/work.txt
My .gitignore file that doesn't work:
/a/*
!.keep
Unfortunatelly, you cannot reinclude files at directories ignored by previous rules, according to the gitignore Documentation:
It is not possible to re-include a file if a parent directory of that file is excluded. Git doesn’t list excluded directories for performance reasons, so any patterns on contained files have no effect, no matter where they are defined.
So this
/a/*
!/a/**/.keep
will only reinclude /a/.keep but not the others.
You'll have to exclude each file pattern under /a explictly.
/a/**/*.txt
/a/**/.ignore
/a/**/.alsoignore
UPDATE: Or a better solution is to create the following .gitgnore at your /a subdirectory:
*.*
!.keep
(the only drawback is that this solution will also keep files with no extension)
In your case, you should use:
/a/*
!**/.keep
From the gitignore documentation:
A leading "**" followed by a slash means match in all directories. For
example, "**/foo" matches file or directory "foo" anywhere, the same
as pattern "foo". "**/foo/bar" matches file or directory "bar"
anywhere that is directly under directory "foo".
Suppose I have a directory structure like
C:\Users\Desktop\abc\d
I want to rar archive the abc folder so that the structure of rar is:
abc\d
When I try using powershell to archive, winrar replicates the full path inside the archive, like:
\Users\Desktop\abc\d
I dont want the full path to be created inside the archive
Here's the script:
https://gist.github.com/saurabhwahile/50f1091fb29c2bb327b7
What am I doing wrong?
Use the command line:
Rar.exe a -r -ep1 Test.rar "C:\Users\Desktop\abc"
Rar.exe is the console version of WinRAR stored in same directory as WinRAR.exe. You can use this command line also with WinRAR.exe if you want to see the compression process in a graphic window.
a is the command and means add files to archive.
-r is a switch to recursively add all files and subdirectories including empty subdirectories to the archive.
-ep1 is another switch which results in execluding base directory.
For this command line the base directory is "C:\Users\Desktop\" and therefore the created archive Test.rar contains only abc and all files and subdirectories in directory abc which is what you want.
One more hint: Using the command line
Rar.exe a -r -ep1 Test.rar "C:\Users\Desktop\abc\"
results in adding all files and subdirectories of directory abc to the archive, but without directory name abc being also stored in the archive. The backslash at end makes this difference.
In other words: On using switch -ep1 everything up to last backslash in file/directory specification is not added to the archive.
For more information about available switches see the text file Rar.txt in the program files directory of WinRAR.
