this is my sed script
#
# insert the line '-A INPUT -i eth0 -j ACCEPT'
# in iptables
#
/-A INPUT -i eth0 -j ACCEPT/a
-A INPUT -i edge0 -j ACCEPT
but when i run sed -f script iptables. it just echo's it to the the screen with my line added and not into the actual file. anyone know what i am doing wrong?
I am browsing our repository and I want to get this folder but all of the files there have ",v" in the end of their filenames and if you open each file, they have some written data which are headers for version control before the actual content of the file. I want to extract the actual content to make the file my_file.c,v --> my_file.c. Is there a command to do this?
I am having lock error and permission errors so I cannot checkout manually using CVS.
I have a large number of folders that each contain quite a few files of varying sizes (from a few bytes to 400kb or so), mostly smaller ones. I need to get the actual (not the disk usage) size of these folders. Is there any way to do this with a command like 'du'?
View 4 Replies View RelatedI multi-boot several Linux distributions with an assortment of additional data partitions. I get frustrated whenever fsck is forced during boot. (It ONLY happens when I'm in a hurry don't you know...) So I wrote a script to automate forced fscking when I do have the time. (And/or while I'm doing something else in another workspace.
Because I multi-boot, I've learned that udev doesn't always assign the same device name to each drive for all distributions. I've had the same partition identified as hda5, sda5, & sdb5 by different distributions (without doing anything to affect the boot order) So my solution is to keep a list of partitions in a specific file on each distro with valid device names according to that distribution's udev process. Actually I'd use LABEL= instead but the labels don't show up in /etc/mtab, and I like to make sure a partition isn't mounted before I try to fsck it.
I can make this work in a for loop using cat. But I've seen so many things about NOT using cat that I wanted to rebuild my script. I can make this work with a redirect instead of cat via a while loop, But I "LIKE" old style for loops. But I can't seem to find a way to make a redirect work with one. I thought this might make a good first �LinuxQuestions.org� question. I'm also open to any other suggestions on better/alternative methods... Is it possible to redirect from a file into an actual for loop?
My script is as follows:
Code:
#!/bin/bash
# FsckEm I script to force file system checking on unmounted ext2/ext3/ext4
# partitions in preselected list. FsckEm accepts no options. Partition

I'm confused about "hard link" feature. I've been learning from my UNIX Academy DVDs training that hard links to a file can be many and each of them is an effective filename for the associated data. So let assume that we have some very sensitive data in a file and we want it to be deleted and file has 20 links. I "delete" a file, but in fact I deleted only one "name" of it. My understanding from the training that data is still there until we delete the last associated hard link. But how can I find the names of all of them? If we have the names, they can be removed one by one. Or may be there's command that can trace all the "names" and remove them at once?

View 14 Replies View RelatedI use amarok 2 and I have a lot of files that are titled "Track #.mp3", in Amarok I have changed them to see as the real songs but the actual files are still the same. Is there a way to change the actual file names using amarok to match the tags I have inside of amarok? The reason why I'd want to do this:
1. If my home folder becomes corrupt I don't have to redo 100's of songs (I have a backup but none the less
2. If I ever decide to use another program or if I'm in W7 using Windows Media Player classic it'd be nice to have it recognize the correct files without having to double up on the tag editing
If this isn't possible I'm going to wishlist it because I think it's functional and having a bunch of Track# files is a pain but impossible to get around when you have a lot of mix cd's.

I am trying to figure out the "actual" disk size used by my system. When I run the "df -h" command,I am not taking here into consideration the shared memory of 2Gb as it is a sort of virtual shared memory and is not allocated physically. Is that correct ?

View 2 Replies View RelatedI recently setup a new Linux server running Fedora 10. For some reason all ping response times are rounded to the nearest 10ms. For example, running the simple command "ping yahoo.com" give the following sample results:
64 bytes from ir1.fp.vip.re1.yahoo.com (69.147.125.65): icmp_seq=12 ttl=57 time=60.0 ms
64 bytes from ir1.fp.vip.re1.yahoo.com (69.147.125.65): icmp_seq=13 ttl=56 time=50.0 ms
64 bytes from ir1.fp.vip.re1.yahoo.com (69.147.125.65): icmp_seq=14 ttl=56 time=40.0 ms
64 bytes from ir1.fp.vip.re1.yahoo.com (69.147.125.65): icmp_seq=15 ttl=56 time=50.0 ms
I could post a larger result set but its all the same... every response is rounded to a multiple of 10ms. This wouldn't be a big deal except that the server is running Nagios for monitoring so accurate stats are important. The Nagios check_ping and check_icmp commands are also returning rounded off results. How can I get ping to simply respond with the actual response times rather than a rounded off number?
I have to administer a few mail servers, a mail log server, 4 nameservers and a web server -all running on Centos 5 server distributions. Now I have a task: to avoid accidental crashes on the production servers while installing updates, my boss asked me to do clones (these clones will all be VMware virtual machines) of the servers (EXCLUDING the actual e-mails and mail log contents) and then to run those clones on VMWare Server. This way, first I will install and test updates on the clones and - if they will be running without crashes - I will apply the updates on the real production servers themselves. I have already installed VMWare Server 2.0 I have a few questions:
- How do I build the virtual machines to exclude the actual mail files and mail logs? Can I use VMware Converter for this purpose, or do I have to use another program?
- How do I actually do this cloning? Is there a tutorial on how to do this?

I have an ISO of a game I own that shows up as 5gb. When I mount the ISO like this:
mount -t iso9660 -loop game.iso /mnt/loop
and go to /mnt/loop and execute
du -hs
it returns 2.5gb. Examination of all the files and directories in /mnt/loop does indeed add up to 2.5gb. So my question is what happened to the rest of it? Does the 5gb ISO contain a bunch of empty space? Should I try to burn it to a DVD and see what happens or should I burn it to a dual layer disc? I don't want to waste a dual layer disc if I don't have to.
Is there a git client that doesn't require git to be installed? Every client I've found so far requires the binary "git" to be installed on your system and is simply a wrapper to that. Does anyone know of an actual standalone git client?

Im trying to find a way in redhat to see if there is a command that could tell me the actual used memory by the system.

Is there a way linux can report the true used memory and not the cached/buffer etc? if there is not specific command for that, can someone tell me a bash script that could calculate used-cached ?

I recently bought a new pc and installed Ubuntu on it. It came with a 500gb hard drive and during installation I manually partitioned it as follows:
10 gb (ntfs) for a windows partition
15 gb (ext4) mounted on /
4 gb for swap
the rest (470gb - ext4) mounted on /home
I've just installed a few apps from the repository, nothing big (about 500 mb in all), but in the 'file system' tab in 'system monitor' it says that for /home I have a total of only 432 gb, of which just 408 gb are available, with 500mb used. According to this, around 60gb of space have just vanished into thin air. Where did all this missing disk space go? The disk is brand new and there are no bad sectors in it.
