Ubuntu :: Can't Get Chmod To Function Recursively
Jan 12, 2011
it seems to me I can't get chmod to function recursively. I have a folder with a couple subdirectories in it and a few in each of those etc. Now, I want to give everyone read-write on all .c files. So, I typed in terminal:
Code: chmod -R 666 *.c However, none of the .c files in any of the subdirectories were touched, i.e. I could have accomplished exactly the same thing by typing
Code: chmod 666 *.c I did RTFM, and it seems that what I did initially should have been the ticket. What am I doing wrong?

Is it possible to change only directories access permissions recursively with some linux command. I need to set x (access) permissions on directories but not execute on files. [URL]
chmod - change file access permissions
-R, --recursive

This should be a simple thing to accomplish, but I can seem to figure it out. Essentially, I want to have a bash alias or function that will let me recursively grep the current directory. A while back I added this to my .bashrc:
Code:
alias rg="grep -r --exclude=*/.svn/* --exclude=*.swp"
This works fine, (and also ignores any svn and vim swp files), and I can call it like:
Code:
rg foo *
However, 99.999% of the time, I am only interested in searching in the current directory, so the "*" is a bit redundant. Also, I would say 5-10% of the time, I am typing faster than thinking and forget the "*", so grep just sits there trying to read from stdin. It's a pretty minor thing, but ideally I'd like to be able to just type:
Code:
rg foo
I've tried creating a function to handle this:
Code:
function rg(){
grep -r --exclude=*/.svn/* --exclude=*.swp $1 *
}
but it behaves exactly the same as the alias above. escaping the "*" with 's doesn't work, and neither does trying `pwd` (or even a hard-coded path) in its place.

I accidentally did a 'chmod +x foo' when i meant to do a 'chmod a+r foo'.

I bought a multifunction stylus sx218 Espon model and I can not run the scanner function. I did some research and found a few solutions and very functional. I hope someone solves the problem. My version of openSUSE 11.2.

I am doing some Linux kernel programming for my research project. I need to record the timestamp (by using cpuid and rdtsc) when an interrupt handler (top half) is first invoked. Due to the time critical nature of the problem itself, I have to do the timestamping inside the interrupt handler itself (the first operation when the handler is called). However, I understand that tasks that are not so time critical should be deferred to a tasklet function (bottom half) for processing because other interrupts are disabled in a (top-half) interrupt handler. I am currently out of idea on how I can pass the timestamp information that I have obtained in the interrupt handler to the corresponding tasklet function.

I'm currently using OpenSuse 11.1 web server. This is bad since 11.1 is no longer supported. the reason why I am using it is because Function set_magic_quotes_runtime() was no longer being used. (so I was told)
That being said, is there a way to get Function set_magic_quotes_runtime() to function on the newer versions of OpenSuSE?

the function terminates if no key is pressed for 10 consecutive seconds. I tried using the -t option as suggested in some forums, but my version of showkey doesn't have the option of changing the timeout. The options I get are:
-h --helpdisplay this help text
-a --asciidisplay the decimal/octal/hex values of the keys
-s --scancodesdisplay only the raw scan-codes
-k --keycodesdisplay only the interpreted keycodes (default).
Is it possible to write a script to use this function and still keep the function active until an interrupt is recieved?

I looked on the net for such function or example and didin't find anything, thus after having made one i guess it would be legitimate to drop it to see what others thinks of it.
#!/bin/bash
addelementtoarray()
{
local arrayname=$1

I just finished setting up my home ubuntu home server. Installed LAMP and it works beautifully. The problem is everytime I upload a file through FTP into the server, the file changes permission even though I did chmod -R 755 www. Si everytime I upload a file to my server i need to run the command chmod -R 755 /var/www

or at least, it doesn't seem to. for some reason, my .txt, .doc, .rtf, and other files that shouldn't have the execute bit set often seem to (i think i know why, but that's not important). it's my understanding that this command should, for example, remove the execute bit from all .rtf files recursively (that is, from .rtf files in subdirectories too):
Code: chmod -R 666 *.rtf i've read help and the man page for chmod, and it seems that -R switch should make chmod work recursively, but it only alters files in the present working directory. could someone point out what i'm doing wrong?

I have been working closely to the Katana boot kit here recently, and this is bugging me. I am trying to use a new program to Katana called Forge. I have it on my flash drive, and I open the properties to make it executable, and when I click something it automatically changes back. I have tried the basic stuff, sudo nautilus.

I have spent the last 2 hours trying to get this to work and it is driving me crazy, I have a 11.04 box and have setup some zfs filesystems for data storage, I have 2 users and have created a group called media and added both of the users to the group. I have changed the group of the directory to media and have set chmod g+s
root@saturn:/tank/data# ls -l
total 8
drwxrws--- 2 root media 2 2011-06-18 13:59 Backups

I have an external fat32 hard drive. It already has some files on it. Now, I mounted it and it shows the owner to be root. fine. but when I change the permissions, it does not seem to change it. I am not able able to access the directories, even as root !.I was able to create directories, but "luckybackup" wan not able to write to it due to permissions. I take it the lucky backup is executing as root/ but even otherwise, if I do chmod ugo+rwx, why do the permissions dont change ? (no erorr message by chmod).
here is the stuff: (ext drive mounted at /seagate)
rootubuntu--seagate# chmod ugo+rwx *
rootubuntu--seagate# ls -l
total 128
drwxr-xr-x 10 root root 32768 2008-08-11 21:03 HPComputerKeyFolders
drwxr-xr-x 9 root root 32768 2008-08-11 21:02 Other
drwxr-xr-x 2 root root 32768 2007-04-06 18:27 Recycled

I've got a directory of geographic data with ~2,000 archives. Each archive (e.g. foo.zip) has two files, the second of which I'd like to remove:
Now, I can remove the _num.tif file with the command:
How do I do this with ALL the files in the directory? If I try the -r (recursive) option, that fails with -d.

I am hoping someone already has a script or knows of an app that will let me do this fairly easily - I have a fairly large folder structure that goes several levels deep, etc. In many cases there are duplicate file names that are not really different, e.g.,
/home/chris/folder/folder1/doc1.doc
/home/chris/folder/folder2/folder3/doc1.doc
I want to recursively go through /home/chris/folder and move everything to /home/chris/another_location/ without subfolders and renaming duplicates as appropriate, e.g.,
/home/chris/another_location/doc1.doc
/home/chris/another_location/doc1_1.doc

I was wondering if anyone knows how to change the timestamps of folders recursively based on the latest timestamp found of the files in that folder.
So for example:

total 55220

I would like to use the command line to compare two directories against each other. I have two folders called music collection that have evolved over the last year on two separate computers. 90% of the two folders are the same, but there are small differences. I would like a solution that will print out all the differences so I can analyze them and choose what I want to do with them, before merging the two folders. for example.I would like some kind of output that shows the differences and where its located.
comparing MusicCollection1 and MusicCollection2
dif1.mp3 located in MC1/folder1 (this one I might want to keep and merge over)
dif2.mp3 located in MC2/folder3 (while this one I might realize does not exist in both folders because I deleted it for a reason)
I've looked at sort, uniq, and even tried scripting my own solution, but haven't come up with an elegant solution thus far. Its important that it is recursive because there are about 15 folders in Music collection and more folders under those 15.

I'm such a newbie when it comes to Ubuntu, or any Linux varient, period. I was trying to install a driver for an HP All-in-One Printer and was trying all kinds of commands from different Google searches... still unsuccessful in the installation. I downloaded the file to my desktop, but after using a Chmod command someone mentioned, I now have a folder on my desktop named:
hplip-3.9.12
i right-click
select
properties
Basic Tab
Type:folder (inode/directory
Contents:unreadable
Location:/home/mesk/Desktop
Permissions Tab
Owner:root
Group:root
"You are not the owner so you cannot change these permissions". The folder's icon on my desktop has a red box with white circle on the middle right side and a lock symbol above that. I'm the only user so I don't get why the permissions are protected from me, how do i undo this?
