# recursively chmod

I was attempting to chmod folders and also documents with:

find . -type d -exec chmod 755 {} \;
find . -type f -exec chmod 644 {} \;


1. Just how to do it in one line making use of find and also leaving out the directory sites . and also ..

2. Which method is much better, find -exec or xargs?

You can do this with the called debates to chmod:

 chmod u=rwX,go=rX {}


The resources X is the key component below which transforms the approval to executable just if it is a directory site. See the manual page for even more information.

Sherlock obtained (1 ), for (2) xargs is usually better as it permits even more practical syntax and also much less covering conjuration expenses. Recognize the -print0 and also -0 alternatives to find and also xargs specifically as courses with rooms and also unique personalities can fumble the jobs.

For a one - time run, the distinction actually should not matter unless you are chmodding a massive tree. If you do this usually adequate to define right into a manuscript, I would certainly make use of xargs.

Is making use of find or xargs required?

Otherwise, you can make use of :

chmod -R u=rwX,go=rX *

find . -type d -exec chmod 755 {} + -or -type f -exec chmod 644 {} +


find ... -exec ... + resembles find ... -exec ... \; other than that the command is implemented just as soon as per huge set of matching documents.

Once, find OPTIONS... -exec COMMAND... \; needed to act upon one documents at once. So xargs was designed to team activities for performance. Yet xargs presented its very own share of problem : it anticipates input that is priced estimate in such a way that find can not generate. So find OPTIONS... | xargs COMMAND... is no excellent unless you recognize that your documents names do not have any one of '"\ or whitespace.

After that GNU designed find OPTIONS... -print0 | xargs -0 COMMAND..., which permits any kind of personality to show up in a documents name. Yet it took a long period of time for any person else to embrace it, and also in the meanwhile Sun (I assume) designed find OPTIONS... -exec COMMAND... +, which does the very same group work as xargs, without the included difficulties (longer command line, restriction to one per find command). Currently find ... -exec ... + is typical (it's in Single Unix v3), and also extra extensively readily available than xargs -0. Unless you need to keep compatibility with an old Linux system, simply forget xargs.
