Dual pane file viewer, not manager

Sean Con — Mon, 07 Apr 2014 13:21:52 -0400

Hello, here is my situation

I have multiple papers, in multiple directories. let us call the papers A, B, C, D ... and i have to write reports often, where i have to answer questions like q1,q2,q3,q4 ...

Now, what often happens is, I notice that the answer to qi is in , say paper A, G, and K. The answer to Q2 is in B, E, the answer to Q3 is in A, C,D,E and so on.

So I want a software like this:

It has to panels, and a bottom pannel to display additional information. In the two panels, the user can add a symbol / link, which will point to a particular file - can also drag/drop a file on it, and it will capture the files path. clicking on it will lauch the file. and the user should be able to move the symbols (with the path to file in it) between two panes, but it will not change the location of the file in the HDD.

Does such a software exists?

copying a file on a jfs filesystem, does not follow acl guidelines

synthnassizer — Mon, 05 Aug 2013 18:36:43 -0400

Hi everyone, I have a jfs filesystem

/dev/md2 on /mnt/hd2 type jfs (rw)

to which i am trying to copy some folders into target folder /mnt/hd2/videos/movies/.

note: I am actually not using this target folder directly, but a symbolic link in my home folder that points to the target folder.

Now, the folder /mnt/hd2/videos/movies/ has default group acl enabled:

nass@stargaze:/mnt/hd2/videos$ getfacl Movies/
# file: Movies/
# owner: nass
# group: shares
# flags: -s-
user::rwx
group::rwx
other::r-x
default:user::rwx
default:group::rwx
default:group:shares:rwx
default:mask::rwx
default:other::r-x

I copied the folders from a temporary folder and expected to get the group write permission to be set as well, instead the folder looks like this:

drwxr-sr-x+ 2 nass shares        24 Aug  6 01:12 The_Movie/

I had set acls on the "videos" folder initially, and all the subfolders have inherited the default from that top folder. What have I missed?

how do i force upperdir overlayfs to reread/reload lowerdir

badgerhill — Mon, 07 May 2012 08:53:25 -0400

i am having the following problem with an overlayfs: I can mount an overlayfs fine using the following line in my etc/fstab

none /home/student overlayfs lowerdir=/home/student,upperdir=/home/.student_rw 0 0

this works great and the mount command displays the overlayfs corretly:

 pc:~$ mount -l -t overlayfs
 none on /home/student type overlayfs (rw,lowerdir=/home/student,upperdir=/home/.student_rw)

so now when a student logs out of the machine i delete the contents of /home/.student_rw using a script - which also works fine.

the problem is that the student logging in, should find a clean home directory with the settings preconfigured in (/home/student) as the overlayfs does not touch the lowerdir folder.

the exact same approach worked very well for aufs, which are no longer supported in precise.

interestingly, the overlayfs approach works fine as long as i reboot the machine. so how can i fix this problem? for me a possible solution seems to be to let the upperdir reread the lowerdir. how would i do that?

thanks

secure automatic connection to MS-Windows file share (cifs)

daves dad — Wed, 29 Feb 2012 09:05:12 -0500

I can mount a windows file share with sudo mount -t cifs -o credentials=~/Files/server-mount/credentials //sbs2008/local ~/Files/server-mount/. I would like to do this but:

~~Without root privileges.~~ (I can do this one, if I solve the other two.)
Without storing password, unencrypted.
Automatically on login.

I am using kubuntu 11.10

What to think about when installing on an SSD?

aron — Wed, 21 Sep 2011 11:34:44 -0400

What do I need to think about when installing Linux on a SSD? You want to limit the writes/reads so the SSD don't get worn out right?

What filesystems are preferred? What filesystems are not?

What about swap?

Anything else that is good to think about?

I think I will use Debian or Mint.

Ideal backup directory

henok — Mon, 15 Aug 2011 15:06:15 -0400

What is the ideal place for saving backups of code, websites, database, etc? /var/backups is reserved for backups of system files. I suppose one can create /var/backup but then users would have to be careful and pay attention to the distinction between backup and backups. Another possibility is to create a new partition and mount it at /backup, but that would be an over-kill. So, any other suggestions? Thanks.

Cannot create files even though I have group write permissions.

Joehillen — Tue, 15 Feb 2011 03:38:33 -0500

I've run into a bizarre issue.

I'm working on a project with a friend. I created a team group and added us both to it. I gave the directory group write permissions. I even set the sticky bit to make sure that the group setting persists. My friend is able to create files, but I am not. I get an error:

joe@server:/opt/project$ touch file
touch: cannot touch 'file': Permission denied
joe@server:/opt/project$ echo "test" > file
bash: file: Permission denied

Here are the permissions:

joe@server:/opt/project$ ls -al
total 20
drwxrwsr-x 4 root team 4096 2011-02-12 20:31 .
drwxr-xr-x 6 root root 4096 2011-02-12 17:10 ..

And I am sure I am in the group:

joe@server:/opt/project$ grep ^team /etc/group
team:x:1003:joe,friend

Any ideas?

Is BtrFS stable enough to be used

martvefun — Fri, 16 Jul 2010 16:47:11 -0400

Hello,

I heard a lot of good things about BtrFS. Everybody agree on his qualities (next generation file system for Linux).
Meego uses it as standard file system
Ubuntu may use it for the next version
...

So is BtrFS finally stable enough to use it to install my OS ?

ext3 part mounted as swap - can I recover?

Matyas — Thu, 01 Jul 2010 17:28:20 -0400

During mitigating a recent hardware failure (using another drive to boot from while waiting for the bad one to be fixed/replaced under warranty) I caused some self-inflicted damage.

By mistake I reformatted(?) an ext3 partition to be used as swap because I thought that the partition has no useful data. I was wrong and now (after the failed drive is back) I realized that I was wrong...

I have 4G memory and the partition was 4G also. I suspect that I did not run out of memory and needed the swap really. I was using a debian install CD and I do not recall that I asked for the partition to be cleared explicitly.

What are my chances of recovering the contents of this partition? Any tool you can recommend?

(The tags are not the best I am not allowed to create new ones: ext3 swap data-recovery).

Thanks!

How do I chmod a file in USB device with Built in Rom that displays as iso9660 (ro filesytem)?

James 1 — Sun, 27 Jun 2010 07:22:01 -0400

Hi - I am using a data transfer cable (by targus) to move files between computers. It moves files quickly between macs and pcs etc but I am unable to get it to work on Linux (Ubuntu Lucid Lynx). The problem is that the software is that is installed is autorun from the device itself by the usb device mounting itself as an iso9660 Cd rom. This is a brilliant idea but I am unable to chmod the executable bit on the program file in order to wine it up. I have tried links, symbolic links and mounting it in everyway I can think. It's an unusual device and I am not that experienced as a linux user (25 years + with pcs though so I can find my way about) so any help would be greatly appreciated.

file with no inode number

jk04 — Wed, 12 May 2010 01:39:10 -0400

Hi,

Here is a file which shows up on a webserver running debian 4 and joomla

ls -li
??--------- ? ? ? ?                ? icon-48-stats&png

Any idea why ls displays such a nonexistent file?

Regards,
