view only permission?

robertkwild · 04-23-2015, 08:58 AM

hi all,

i know there is read (4) write (2) execute (1) and you can set it for owner, user other but i just want to know is there such a permission as just browsing the directory ie view only, so the user cant read/open or execute the file just view the filename in the directory?

thanks

Yes. Do:

Code:

chmod a=r dirname

You may set permissions for group and/or other and not owner if you like.

i know r is recursive

basically i have created an apache server and have got it to show my directory under docuroot on a web browser so it lists directorys and files, but i dont want the end users to actually open/read the files, i just want them to browse directorys and list the filenames in the directorys, i have tried your command but to no avail

when i type in -

chmod a=r /var/www/html/view

when i refresh the webpage i get this

'a' stands for all (ugo).

Just check this with 'ls' command locally. Perhaps html folder has also restricted permissions.

r is for reading, not for recursive.
You need to set permissions on the dir to allow reading its content and you need to disable(or set) read/execute permission on files/dirs inside the dir one by one.

awesome i have done it

so

chmod -R 755 /var/www/html/view

i can open all files under root and all files under sub folders on a web browser

but when i issue this command

chmod 700 $(find /var/www/html/view/ -type f)

when i then try to open files again i get a forbidden page

many thanks, much appreciate everyones help

glad to help you
if you really want to say thanks just click on yes.

Your command may fail if the list of the files was too long. In that case you can also try to use:

Code:

find  /var/www/html/view/ -type f -print0 | xargs -0 chmod 700
or
find  /var/www/html/view/ -type f -exec chmod 700 '{}' \+
