Recursively Look For Files With a Specific Extension

Recursively find files with a specific extension

My preference:

find . -name '*.jpg' -o -name '*.png' -print | grep Robert

Recursively Find Files With Particular File Extension and Content

What do you mean by keyword? Is that a word, present inside the file? Or is it a part of the filename?

In case it's the part of the filename, you can use file: in the Windows search, like in following example:

file:*keyword*.py

This will show you all files, called *keyword*.py. After you've done that, you might change your Windows explorer's view, clicking on the "View" tab and choose "Details", this will also show you the directory where those files are located.

How can I recursively find all files in current and subfolders based on wildcard matching?

Use find:

find . -name "foo*"

find needs a starting point, so the . (dot) points to the current directory.

recursive search of file with specific extension

You want the sum after filtering all the files:

def fileCount(path, extension):
    count = 0
    for root, dirs, files in os.walk(path):
        count += sum(f.endswith(extension) for f in files)
    return count

files returns a list of files so sum(f.endswith(extension) for f in files) will give you the count of all the files ending with the given extension.

Or just return the sum of all:

def fileCount(path, extension):
  return sum(f.endswith(extension) for root, dirs, files in os.walk(path) for f in files)

How can I grep recursively, but only in files with certain extensions?

Just use the --include parameter, like this:

grep -inr --include \*.h --include \*.cpp CP_Image ~/path[12345] | mailx -s GREP email@domain.example

That should do what you want.

To take the explanation from HoldOffHunger's answer below:

• grep: command

• -r: recursively

• -i: ignore-case

• -n: each output line is preceded by its relative line number in the file

• --include \*.cpp: all *.cpp: C++ files (escape with \ just in case you have a directory with asterisks in the filenames)

• ./: Start at current directory.

How to retrieve recursively any files with a specific extensions in PowerShell?

If sorting by Length is not a necessity, you can use the -Name parameter to have Get-ChildItem return just the name, then use [System.IO.Path]::GetFileNameWithoutExtension() to remove the path and extension:

Get-ChildItem -Path .\ -Filter *.js -Recurse -File -Name| ForEach-Object {
    [System.IO.Path]::GetFileNameWithoutExtension($_)
}

If sorting by length is desired, drop the -Name parameter and output the BaseName property of each FileInfo object. You can pipe the output (in both examples) to clip, to copy it into the clipboard:

Get-ChildItem -Path .\ -Filter *.js -Recurse -File| Sort-Object Length -Descending | ForEach-Object {
    $_.BaseName
} | clip

If you want the full path, but without the extension, substitute $_.BaseName with:

$_.FullName.Remove($_.FullName.Length - $_.Extension.Length)
