I presume that if this is possible it would need to be done as root (or as a user who shares root's UID of 0).How can a process be launched so that it does not show up in a ps aux or ps ef or top listing if the command is run by non-root?Is this even possible?The distributions I typically run are RHEL/CentOS and Ubuntu - so if there is a distro-specific answer, that's ok, too.
View 1 RepliesIs it possible for a non-root user to hide themselves from the output of who/w, so that they can be logged in without other users seeing it? I think that the file /var/run/utmp might have something to do with this, but it's not writeable by non-root users (permission 644). I'm fairly certain that this can be done by a non-privileged user (because someone told me that they were able to do so), but I don't know how they did it and can't ask them right now.

View 2 Replies View RelatedI can't seem to find a way to do this, so maybe it's not actually possible, but I was wondering if there was a way to list all files that link to a file.
For example.
touch a
ln a b
ln a c
I want to find out what files link to a (not symlinks, mind you), assuming that this is more complicated (they are spread around to different directories).
I kind of understand about the filesystem storing links in one area and data in another, so I understand it probably takes more work to find a link from a file location than the other way around.

View 1 Replies View Relatedlist filenames one-per-line, in BASH without including directories. I think he was either wrong or making that up. There is a way to list just the names and one per line but there aren't any arguments I can find that can be used to exclude directories.
Code:
IFS=', '; files=`ls -m`; for i in $files; do if [ -f $i ]; then echo $i; fi; done That does only use ls as a command, however he said his GSI thought he could do it without all that...

Im trying to list the cpu usage of all process that have a cpu usage of 10% or more. Im not interested in the lower usages. Im using the top command and can get a list of all the cpu usage for all the process but cant only get the processes with 10% or more. I'd want these processes sent to a new file. Would I be able to cat the cpu usages and PID into a file?

Code:

How would I limit this to searching for the text 'SomeString' or 'SomeOtherString', but only if the file has extension .php, .inc or .js? Also - what piping to xargs does here? I don't understand how this command actually works.

Description of what the code does or what i intended to do:
1. Created a child process from parent process using 'fork()'
2. Sent a signal 'SIGALRM' from child process to parent process using 'sigqueue' function.
(The Third parameter of 'siqueue' function contains the message (message msg) which the child process wants to send to the parent process.'msg' is a stucture instance containing a) pid of child and b) string) 5. Print the 'msg' sent by child process inside the signal handler function 'sig_action_function' of the parent process I am getting some junk value when this line is executed
Code:
printf("%d
",msg->cpid);
I expected to get the pid of child process, which the child process sent to parent process through the signal.

View 1 Replies View RelatedIs there a command to return a recursive listing of sub-directories and the number of files in them? I have found plenty of ways to give me the total number of files in a directory structure, but none that gives a list of the sub-directories with the number of files in them. "du" gives me a listing of directories with their sizes, but I couldn't find an option (or any other way) to give me the number of files as well. Ideally, I'd like to get list with "Size" "Files" "Dir name" - And the order of the columns doesn't matter. Is there a "simple" command line solution or do I need a shell script for that?
View 5 Replies View RelatedI have, for example, a folder called "MyFolder" and it contains 3 files: MyFile1, MyFile2, MyFile3. The only file that I do NOT want a particular user/group to even see that it exists is, for exmple, MyFile2.So, when they do a directory listing on MyFolder, they should only see MyFile1 and MyFile3. How can this be done in Linux? The important thing is that it is not just preventing them from "executing" MyFile2, but to prevent them from even knowing that it exists by not including it in a directory listing.This is a simpified example using one file, but in reality, I have lots of files and some of those that I want to block are also subfolders.It is very important for me to hide the existence of certain files/folders when the user does a directory listing. It's also important that the files stay in their current folder (that is, I can't use a workaround which requires moving all the files into a separate folder and then securing that folder).
