Hello.

I need to change the permission of all files with the following extentions inside of a certain directory to 777:
.dat
.bak
.lock

There are over 200 files in 15 sub-directories.

I have ssh access. How can I change the permissions of all the files in all the subdirectories at once? Thanks!

Use the find command:

find /path/to/parent -name "*.dat" -print | xargs chmod 777
find /path/to/parent -name "*.bak" -print | xargs chmod 777
find /path/to/parent -name "*.lock" -print | xargs chmod 777

You can also combine the three extensions into one command:
find /path/to/parent -name "*.dat" -print , -name "*.bak" -print , -name "*.lock" -print | xargs chmod 777

Or try this one (it is almost equivalent ) :

find /path/to/parent -name "*.dat" -exec chmod 777 {} \; , -name "*.bak" -exec chmod 777 {} \; , -name "*.lock" -exec chmod 777 {} \;

tkalchev,
your solution will be slower: You are forking the chmod command for every single file. The xargs mechanism collects a number of file names and then forks one chmod command for a number of files.

True, but no chance for "argument list too long" error :)

... and for 200 files it does not make a big difference :-)
