General :: How Many Files Should Be Listed As Open Under Lsof
Jul 10, 2011
I am not an advanced Linux user. I have a VPS with 768MB of RAM running CentOS.I executed the lsof command as root and I see that there is a list of 3000 files. Usually, how many files should be there? My system is getting very slow, so is this list too long?How do I know which files to keep and which to close?I have seen that there are multiple copies of the same files with different PIDs. There are many log files in the list that I have not opened. Is this normal?total used free shared buffers cachedMem: 104287 492 103794 0 0 0

I have a file that is a list of other files, lets say FilesIWantToTar.dat. I want to say something along the lines of tar -c input-file=FilesIWantToTar.dat archive.tar or similar. Does the tar utility provide this functionality, or do I need to write a simple script?

I was trying to install some Windows applications in Wine/PlayOnLinux. The result was not very useful for what I wanted and I removed all the application including wine and Playonlinux completely from my computer (9.10 64bit).But I was not really able to completely clean up what I did because when I right click on any files and use "OPEN WITH", I got a LONG list of application with many of them are uninstalled and duplicated.

I am puzzled by this really weird issue that involves Mozilla Firefox 3.6.8. When I add a bookmark (doesn't matter where I add it, could be to the field or to the menu) followed by exiting Firefox and then starting again, nothing happens. The process firefox gets listed with 'ps aux | grep fire' but the program itself doesn't appear, as if it hung before it could get to the display. However, when I remove ~/.mozilla (or rename it) Firefox starts up again nicely. I can only assume that the problem has to do with bookmarks (which is really odd..).

How do you convert Open Office (ODT) documents to Text files?
I have made a report using libre office. Now I wish to continue editing the document using lyx (latex front end). So the ODT file needs to be saved as some .tex file.
I don't see an option to do this in File menu (export/save as). So is there any other plugin to do this?

Through various Windows reinstalls and switches within Linux distros, I have a massive amount of duplication within my music archive (on the order of 7+ dupes of each file). Now, I found a lovely program called "fdupes" and was able to build a list of all the duplicate files, and I'm trying to use "xargs" to remove then. However, when I try and run the command "xargs -0 --arg-file="dupes.txt" rm" or "xargs -0 rm < "dupes.txt"" it give me the following error: "xargs: argument line too long".
how perhaps a different way of accomplishing the same thing?

I use Apache 2.0.55 (Ubuntu) as a document server for a business association. When the document files expire, I change the permissions so that only the owner can open them but I like to leave them on the server so that they are all in one place.
Here is my trouble--when visitors come to the site and get the directory listing, all the document files show up, whether the visitor can access them or not.
Is there some way to configure the server to not show the inaccessible files?
I guess a few technical details might help. During their useful lives, the files permissions are set to 644. Once they expire, I change them to 600. After the change, the files are still visible. Setting them to 000 doesn't help either.
It might be of note, but directories behave differently than files. If I set a directory to 600, it disappears from the listing.

I've got a text file with a list of .gz files, these .gz files are in various sub directories of one parent directory and I've hacked this little script together to copy them from their current location to a new one and spit out any it can't find to "/home/user/not_found" but for the life of me can't get it to run properly!
The shell script as it currently looks:

In order to upgrade a machine that can not successfully upgrade to 10.4 I downloaded and burned the 10.04.1 iso image off the ubuntu alternate download site. In my first attempt I unsuccessfully burned the image with it failing at the very end. I did perform an md5sum on it and received the precise output I got from my second burn attenpt which DID complete successfully. Here is the output:
[code]...
I did research this last night and it seems the common wisdom was to reburn the iso (which I did twice) or copy down the iso again. This I also did and it came down precisely, bit for bit, the same as the first one. Here are the two cksums
[code]...
Is there something wrong with this image on the website or is the error about 1 file being unreadable (could that also mean missing?) be erroneous?

Server - Ubuntu 10.04.1 lts
Client - Kubuntu 10.10
When I try to open any nfs-mounted file using OpenOffice, I get a pop-up window titled "Document in Use". The text of the message is:
"Document file 'abcde.odt' is locked for editing by:
Unknown User
Open document read-only or open a copy of the document for editing." I then have three options - <Open Read-Only>, <Open Copy>, & <Cancel> If I cp any of these files from the mounted directory to my home dir (not mounted), I can open them without problem.Also, my firefox & thunderbird date are in this mounted directory as well (sym links to ~dan/.mozilla & ~dan/.thunderbird). Both of these apps hang when trying to open, leaving two processes behind that need to be manually killed. Again, cp'ing the data out of the nfs-mounted dir onto a local dir resolves the issue, so I am 100% confident there is nothing missing or corrupted in the firefox &/or thunderbird data...
relevant entry in /etc/fstab:
server:/nfs/dan/Documents /home/dan/Documents nfs defaults 0 0
relevant entry in server's /etc/exports:
/nfs/dan/Documents client(rw)

I have a while(1) loop, and the error is: glibtop: open (/proc/stat): Too many open files This error occurs after about a half hour to an hour of running. I've tried running this multiple times, both with using glib_close() at the end of the loop, using glib_init() and glib_close() at beginning/end, and just using glib_init(). The strange thing is these have no effect on the actual glib_get functions.
