Know a better way?

If you can do better, submit your command here.

What others think

find . -type d -exec chmod 755 {} +;

{} +: to let it behave like using xargs

the same command has been posted before

find . -type d -print0 | xargs -0 chmod 755

1. It is much faster of large amounts of files because chmod does not get invoked for every file seperately.

2. And besides null terminating the file name takes care of nasty spaces|quotes|your-favorite-non-printable-characters in file names.

3. Same goes for files:

find . -type f -print0 | xargs -0 chmod 644

In zsh you can do the same with this command:

chmod 755 **/*(/)

It's fast, efficient and works with all filenames (spaces and anything).

To do the same with plain files:

chmod 644 **/*(.)

For those not familiar with zsh wildcards, this is how the above commands work: "**" is the same as "*", but it works recursively down the directory tree, so you don't have to use the find command. Any wildcard pattern can be followed by a set of flags in parentheses (there must be no space between!): "(/)" restricts the matches to directories only, and "(.)" does the same for plain files. There are many more wildcards and flags; this is just the tip of the iceberg.

+1; xargs is better

Comment by asmoore82 462 weeks and 3 days ago

Actually, koukos was right here -- using "{} +" in a find -exec command tells find to build the command with every matching file /before/ execution, so chmod would only be invoked once (unlike using "{} \;" which tells it to invoke the command once for every file matched)

I have a shared drive here in the office which I occasionally get permission problems with for other users, so I use

find . ! -perm /g=r -exec chmod g+r {} +

a lot: turns on the group readable bit for any files that don't currently have it on, in one invokation of chmod.

Beware, the ^above "zsh" method misses hidden files and folders. While there may be a way around this with zsh's options, why waste the time when `find` is Unix standard? Will zsh also search by perms or times? Will zsh combine search methods? Always pick the right tool for the job; `find` is for *finding*

^oops :/, excuse me :[

`xargs -0` is _still_ *better*; the "+" is *NOT* Portable.
