Set executable file permission on Windows for using in Linux

Last Updated on February 16, 2025

with Windows Subsystem for Linux

git update-index --chmod=+x myfile.sh

If you frequently work with .sh files and want to ensure they are always marked as executable, you can configure Git to automatically handle this. For example, you can use a .gitattributes file to define rules for specific file types.

*.sh text eol=lf
*.sh executable

a .bat script for Windows that searches for all .sh files in a folder and its subfolders, and then runs the git update-index --chmod=+x command for each file:

@echo off
:: Get the current directory
set "ROOT_DIR=%cd%"

:: Navigate to the current directory
cd /d "%ROOT_DIR%"

:: Loop through all .sh files in the folder and subfolders
for /r %%f in (*.sh) do (
    echo Processing file: %%f

    :: Add the file to the Git index if it's not already tracked
    git add "%%f" 2>nul

    :: Mark the file as executable
    git update-index --chmod=+x "%%f"
)

echo All .sh files in the current directory and subfolders have been marked as executable.
pause
