How to set chmod for a folder and all of its subfolders and files in Linux Ubuntu Terminal ?

chmod -R 755 will set this as permissions to all files and folders in the tree. You can use the find command. For example:

To change all the directories to 755 (drwxr-xr-x):

find /opt/lampp/htdocs -type d -exec chmod 755 {} \;

To change all the files to 644 (-rw-r--r--):

find /opt/lampp/htdocs -type f -exec chmod 644 {} \;

Check the -R option

chmod -R <permissionsettings> <dirname>

man <command name>

So in this case:

man chmod

If you want to set permissions on all files to a+r, and all directories to a+x, and do that recursively through the complete subdirectory tree, use:

chmod -R a+rX *

The X (that is capital X, not small x!) is ignored for files (unless they are executable for someone already) but is used for directories.

You can use -R with chmod for recursive traversal of all files and subfolders.

You might need sudo as it depends on LAMP being installed by the current user or another one:

sudo chmod 755 -R /opt/lampp/htdocs

To set to all subfolders (recursively) use -R

chmod 755 /folder -R

chmod 755 -R /opt/lampp/htdocs will recursively set the permissions. There's no way to set the permissions for files automatically in only this directory that are created after you set the permissions, but you could change your system-wide default file permissions with by setting umask 022.

chmod 755 $(find /path/to/base/dir -type d)
chmod 644 $(find /path/to/base/dir -type f)

Here's another way to set directories to 775 and files to 664.

find /opt/lampp/htdocs \
\( -type f -exec chmod ug+rw,o+r {} \; \) , \
\( -type d -exec chmod ug+rwxs,o+rx {} \; \)

It may look long, but it's pretty cool for three reasons:

find / \
\( -perm -4000 -fprintf /root/suid.txt %#m %u %p\n \) , \
\( -size +100M -fprintf /root/big.txt %-10s %p\n \)

Traverse the filesystem just once, listing setuid files and  direc‐
tories into /root/suid.txt and large files into /root/big.txt.

Use this:

sudo chmod 755 -R /whatever/your/directory/is

It can really hurt you if you change the permissions of the wrong files/folders.

The recursive command is:

sudo chmod 755 -R /opt/lampp/htdocs

Ensure that appropriate files and directories are chmod-ed/permissions for those are appropriate. For all directories you want

find /opt/lampp/htdocs -type d -exec chmod 711 {} \;

And for all the images, JavaScript, CSS, HTML...well, you shouldn't execute them. So use

chmod 644 img/* js/* html/*

But for all the logic code (for instance PHP code), you should set permissions such that the user can't see that code:

chmod 600 file

chmod 600 file

For Mac OS X 10.7 (Lion), it is:

chmod -R 755 /directory

In Terminal go to file manager. example: sudo nemo. Go /opt/ then click Properties → Permission. and then Other. Finally, change to create and delete and file acess to read and write and click on button apply.
