["python","chmod"]
How do you do a simple "chmod +x" from within python?

I want to create a file from within a python script that is executable. import os import stat os.chmod('somefile', stat.S_IEXEC) it appears os.chmod doesn't 'add' permissions the way unix chmod does. With the last line commented out, the file has the filemode -rw-r--r--, with it not commented out, the file mode is ---x------. How can I just add the u+x flag while keeping the rest of the modes intact?
Use os.stat() to get the current permissions, use | to OR the bits together, and use os.chmod() to set the updated permissions. Example: import os import stat st = os.stat('somefile') os.chmod('somefile', st.st_mode | stat.S_IEXEC)
