General :: Write A Script To Report Useful Information On Disk Utilization For Each User's Home Directory
Feb 27, 2010
I need to write a script to report useful information on disk utilization for each user's home directory.For each directory I need to show: 1. the long listing of that directory entry (but not the files in the directory), so that I can see the rights and owners of the directory.2. The amount of disk used by that directory, in human-readable format, including subdirectories. I need to have two lines for each user one after the other. For example:
/home/user1 directory info
/home/user1 disk usage
/home/user2 directory info
/home/user2 disk usage
The script will assume that all users, except user root, have their home directories in the /home directory (no need to do anything with the /etc/passwd file). And if the administrator adds or removes users, the script should still work correctly (so the script shows the information for all current users).
Here's what I do know. The command "ls -ld /home/user's_name" will give me the info I need for #1. And the command "du -hs" will give me the info I need for #2. What I don't know is how to grab each individual directory in order to apply the above commands to each of them in order. ???
I want to write a shell script which will simultaneously collect OS user information and write in an individual text files.Can anyone tell me the syntax of the script.N.B. The user name will be mentioned in an array within the shell script.
I would like to move a user's home directory to a different disk. Is there a "clean" way to do this? Specifically, is it safe to just copy all the .* files to the new destination and then change the home in the user config? Or are there maybe environment entries with absolute paths which will cause problems with this strategy?
I have a secondary disk which holds a /home directory structure from a previous install of Linux. I installed a new version on a new primary drive and mounted this secondary drive as the new /home. Problem is, even though the users are the same names and I can access the home directories for the users, I cannot login directly to their home directories, as I get the following error: -
login as: [me] [me]@[machine]'s password: Last login: Wed Jan 6 18:34:33 2010 from [machine] Could not chdir to home directory /home/[me]: Permission denied [[me]@[machine] /]$
Now, since the usernames are correct and the users are in the passwd file with the correct home directory paths, could it be user ID's that are different or something else? It's not as though I cannot access the home directories for the users, simply that I cannot log directly into them from a login prompt.
This might see a dump question but I will make it anyway .Here is the scenario:I have two users on my Linux Mint installation:
User A User B
I want User A to be able to write on User B home directory, say /home/B.For this I have changed users's B home directory to look like this:ls -ld drwxrwxr-x 36 B music 4096 2010-09-26 10:31 /home/BI have created a "music" group and assigned to /home/B, so all users that are member of "music" are going to be able to write on User B home directory, right?The answer is No! Not here in my box Can you tell me why?Why users under group music can't write on /home/B if B directory is owned by group music and group music has write permissions?
I'm developing an application in which one user must run java software that I'm compiling as another user. I wanted to give user A permission to see the bin direcory of my workspace, which is in the home directory of user B. I was wondering how can this be done? I gave the bin direcotry full read/execute premissions, but since it's in my home directory user A can't navigate to it.
I know there are a few ways I could get around the problem but they arn't very elegant. I was wondering if there is a simple method for giving a user access to a specific directory without giving access to all the parent directories. I tried symbolic link but user A still can't access it, and a hard link to a directory isn't allowed in Linux. I don't feel like making a hard link to every single file in the bin directory, and I'm not sure that would work anyways, since every recompile overwrites them.
On my laptop for testing, I simply chown each subdir of /var/www to my myuser:www-data. But, now that I am setting up a public facing server, I'm wondering if this is the proper way to do so? If not, what is the best way to allow a non-root account to write to /var/www.
I need to give a user write access to /var/www and its subdirectories. The current directory permissions are as follows:rwx r-x r-x root root
I added the user to the root group but that didn't seem to help.I read I could chmod -R to change the access to write for the www directory and subdirectories but I don't want to change things and mess up the website. How can I give the user access to write to the www directory and subdirectories without messing anything up? Would changing the www directory group owner to his group cause an issue anywhere?
When I log on a root and attempt to issue the command Freshclam to upgrade the virus definitions it attempts or create a new file with a definition name. I get a message stating that the directory isnt writable. The user and group access rights are as follows:
USER = read, write, execute Group = read, write, execute All= read, execute.
The only way I can get around this is by applying a 777 which would be read, write and execute for all. Now, I have a group define with several user ids in it including Root.How do I connect the group with the directory/file so I dont have to apply a 777 access right to group users could issue the Freshclam command.
Ubuntu 10.04 64 bit I ran following command to change username; # usermod -c "Real name" -l new_username old_username but forgot adding -m option to move the contents of the old home directory to the new home directory. Therefore; # ls /home old_user_directory
I must to give ssh connection to own customer. So I want to lock ssh user on own home directory. It is not necessery to reach other folders. I know that ftp user can lock on own folder but I don't know how to lock ssh user.
Is there a way where i can chroot their user home directory, lets say the user login on linux box /home/user, what i wanted to do is to chroot /home/user where user won't be able to browse the filesystem which is /. Tnx
How do I change user's home directory, because right now everything saves into File System and it's almost full(I got windows and Ubuntu installed in the same partition), while the other 120Gb filesystem is unused..
I am new to writing shell scripts. So, please bare with me. I am currently trying to write a shell script which will read the directory path as input from user and will traverse the Dir tree to find all available audio and video files. I have tried to write as much as I could but I don't know where I am making mistake as I get some files to be audio file which are actully tar balls. On the second note there are some files which video but script shows them to be audio. And, some video files are completely skipped. I am giving the shell script below so that you can see. I am using two external files as source which I am attaching.
#!/bin/bash #Let's load the extensions that we want to search for vdExt=$(cat vdExtList) adExt=$(cat adExtList)
This may be a rookie mistake, but I created a user (new user) in Linux on a Ubuntu system and didn't actually create the home directory for this user. Now, when I log in, it says there are problems... If I delete the path home/<new user> and try to log in the system tells me I can use root as home directory but I will likely experience problems, and then it won't let me log in. What is the best way to create this directory with the appropriate permissions? Should I just create another user and delete this one?
Why would rsync insert a user's home directory path in variable expansion when run via cron, but not when run manually. The gory details... Red Hat Enterprise Linux AS release 4 (Nahant Update 6) Linux 2.6.9-67.0.20.ELsmp The script (parts anyway, and simplified)...
So I have a system that is about 6 years old running Redhat 7.2 that is supporting a very old app that cannot be replaced at the moment. The jbod has 7 Raid1 arrays in it, 6 of which are for database storage and another for the OS storage. We've recently run into some bad slowdowns and drive failures causing nearly a week in downtime. Apparently none of the people involved, including the so-called hardware experts could really shed any light on the matter. Out of curiosity I ran iostat one day for a while and saw numbers similar to below:
Some of these kinda weird me out, especially the disk utilization and the corresponding low data transfer. I'm not a disk IO expert so if there are any gurus out there willing to help explain what it is I'm seeing here. As a side note, the system is back up and running it just runs sluggish and neither the database folks nor the hardware guys can make heads or tails of it. Ive sent them the same graphs from iostat but so far no response.
created a user but i forgot to change the home directory permission.so after user created when i go to the user and group mangement i cant see that permission filed related to the home permission directory.my purpose is to stop accessing other user to my home directory,how it can be possible??
i have rhel 5.2 and i want to create user using useradd command without creating user home directory and not throwing any warning/error about not creating any home directory.i have tried useradd -u "$NEW_UID" -g <gid> -d "/home/$1" -M "$1"where $1 is user name and $NEW_UID is i am calculating.it throws error as useradd: cannot create directory /home/$1which i dont want to come , how to prevent this?
