chmod all files 644 and files 755


Hi,

I've got a mass of files sitting in a directory I copied from my windows eons ago.

It has about 150gig of 4mb files the directory tree can go up to 10 levels deep.

Because they were copied off a XP machine, the permissions aren't set correctly.
What i'm after is an EASY way (or a utility) that will chmod all files 644 and all folders 755.. if I have to run two commands to do this, eh, I'll live!

Otherwise, I'll have to elarn how to shell or even worse I'll do it in PHP with exec or system calls, both I don't really want to do due to time constraints.


If anyone can lend a hand I would appreciate it.

Of course: chmod -R 755 /top/directory will set everything to 755 throughout the tree. This means your problem is reduced to setting the x bit to 0 for all files that are not directories... chmod -R -x [file] but you need scripting skills to single out only non-directories from this.

Have fun.

You can use the find command to select just the files and the -exec option to change the permissions:
find top/directory -type f -exec chmod 0644 '{}' \;
find top/directory -type d -exec chmod 0755 '{}' \;

You can also combine both operations into one find command:
Code:
find top/directory  \( -type d -exec chmod -v 755 '{}' \; \) \
                 -o \( -type f -exec chmod -v 644 '{}' \; \)

Or do
Code:
find . -type d -print0 | xargs -0 chmod 0775 # For directories
find . -type f -print0 | xargs -0 chmod 0664 # For files
in the directory where you have the dirs/files.

For whatever reason, when I tried the above I got an error: -jailshell: fork: Resource temporarily unavailable

So, I figured this out, which worked for me.

Code:
for i in `find . -type d`; do  chmod 755 $i; done
for i in `find . -type f`; do  chmod 644 $i; done
Cheers!

The above doesn't work if any of the folders or files contain spaces in their names. You can mess about with the $IFS variable to change the for loop's whitespace handling or you can use a while loop instead, ala:
Code:
find . -type d | while read folder ; do chmod 755 "$folder" ; done
find . -type f | while read file ; do chmod 644 "$file" ; done

I have a slightly different situation but don't wanna make things mudder so ill ask first (should have done to begin with)


have a tri boot sda1 win7 / sda5 Fc20design / sda6 mint 16 and sda8 is home in ntfs


both win7 and fc20 took home partition perms just fine after manually pointing fc20 to sda8 instead of a system-based /home
however when i installed mint it was fine with system-based /home but after pointing it to the sda8 partition I get an error dialog on login stating that the user's $HOME/.dmrc is being ignored and needs chmod 0644 i used another tutorial from a forum to re-generate the file using [$ sudo touch /home/myusername/.dmrc and it shows in a ls -l -a readout but with rwx across the board how can i get this to be rwxr--r-- as it needs to be $ and # chmod 0644 -c ~/home/username/.dmrc don't affect the change..


also is it a file or dir that needs re generated......thanks coming back to linux after over a decade of solely windows
