Getting "Permission Denied" on Dirname and Basename

Getting Permission denied on dirname and basename

As it stands, your script is trying to run the file named in $nquo first with the environment variable dirn set to the value dirname, and then with the variable bnam set to the value basename. Since it is not executable, you get the error message about not being able to execute the file.

You presumably intended to run the commands on the name of the file, which requires either back-ticks or (preferably) $(...) around it:

dnam=$(dirname "$nquo")
bnam=$(basename "$nquo")

open(filename, 'w+') causes Permission Error 13

Look the way you handle paths its very dangerous.
its better if you use "OS"

import os
from tkinter import filedialog

path_to_file = filedialog.askopenfilename(title = "Select a JSON file")
dir_path= os.path.abspath(os.path.dirname(path_to_file))
basename = os.path.abspath(os.path.basename(path_to_file))
fileName = basename.split('.json')[0] + '.csv'
csv_filename = os.path.join(basename, fileName)

Trying to create empty php file gives failed to open stream permission denied wordpress

Finally I find a fix that fulfill my requirement and I am posting here in case anybody faces same situation. Rather creating file in active theme folder, I created a template file in the plugin and used below code to load the template.

function my_page_template($page_template){
    $slug = 'slug of the page where to load my custom template';
    if ( is_page($slug) ) {
        $page_template = dirname( __FILE__ ) . '/templates/my-template.php';
    }
    return $page_template;
}
add_filter( 'page_template', 'my_page_template');

NOTE: This code will not list the template name in the templates listing dropdown (Template) option of pages. It will load the custom template irrespective to assigned template from the admin panel of the pages.

os.path.dirname() and os.path.basemane() are giving weird results

OSX, just like Linux, uses / as a separator. You can get the standard separator for your OS from os.path.sep.

>>> import os
>>> os.path.sep
'/'
>>> path='/Users/apple/Documents/list.txt'
>>> os.path.dirname(path)
'/Users/apple/Documents'
>>> os.path.basename(path)
'list.txt'

Notice that os.path is just constructing "correct" paths, it does not do any checking, if files exist. That would not make much sense, if you constructed a path to create a new file. You could use os.path.exists() for that.

How to Zip a file/folder from QTreeView - PermissionError: [Errno 13] Permission denied:

dpath error...change to a user directory...new code

def zip_file(self,):
    dpath = r'C:\Users\Black Laptop\Desktop\DC.zip'
    if os.path.isfile(self.path):
        with ZipFile(dpath, 'w') as zip:
            zip.write(self.path, basename(self.path))

        print('file zipped successfully!')
    else:
        zf = zipfile.ZipFile(dpath, "w", )
        for dirname, subdirs, files in os.walk(self.path):
            zf.write(dirname, basename(dirname))
            for filename in files:
                zf.write(os.path.join(dirname, filename), basename(os.path.join(dirname, filename)))
        zf.close()
        print('All files/folders zipped successfully!')

Segmentation fault occurs because of dirname api for some particular strings (like . and usr)

You don't include libgen.h thus dirname is not declared thus it is assumed to return an int thus your program is corrupted and you get a segfault.
