General :: Writing To The STDIN Of A Shell?
Jul 28, 2010I am trying to write input to a shell and get the shell to parse the input that I am writing to it as if a user was typing in commands.
Thus far I have tried echoing some text into the shell's FD for STDIN in /proc/<pid>/fd Whilst this displays the text that I echo, the shell that I am writing to never tries to execute the command that I pass to STDIN. What is the difference between a shell taking STDIN from the user and data written to STDIN by another process e.g. echo ? It appears I am missing something fundamental.

Aug 10, 2010I am about to write my first shell script for backing up my server.
These are the steps I have identified so far.
Copy files to be backed up to /srv/backup/ run mysqldump and copy the file to srv/backup/databases run duplicity to backup /srv/backup/* to another folder on my machine
I am writing a bash shell scrip that will be run everyday, and will carry out the three tasks mentioned above.
Note: point 3 (backing up to a local folder) is only a temporary measure - to allow me to understand what I'm doing, since all the tools I am using, are new to me. Once I can backup and restore correctly, I will use duplicity to compress and encrypt the files and upload them offsite.
If my understanding of duplicity is correct (according to the documentation here), the first time I run the script, a FULL backup will be done. Every subsequent backup will then be incremental. I will then force a FULL back on say a weekend.
First things first though - I have a few questions:
I would like to use backup rotation for the 'scheme' described above - I would like some recommendations on what kind/type of rotation to use. Once I have implemented the backup rotation, how can I restore from a particular day back in time (assuming the backup exists of course). ?

Ubuntu :: Writing A Single Shell Script To Change Preview Settings And A Launcher's Icon
Mar 22, 2010I want to write a single shell script that allows me to, once executed from a panel launcher, change the image preview setting between "local files only" and never. Right now i have two tiny scripts, one for local files only and another one for never, that is:
[Code]...
and the other says string "local_only". But that means i need to have two launchers, because i don't know how to write the condition <<when set to never, change it to local only. And is it possible to make a script that also changes the launcher's icon when the preview config is set to one or the other value? That way i'd know what it is set to just by looking at it. It would act as a diagnostic and therapeutic tool XD

Jul 26, 2011how to match to find matches in two different files when comparing timestamps. The fields I'm wanting to match up are in the format:
Jul 26 09:33:02
I have tried reading the file line by line and using awk '{print $1,$2,$3}' which only gets and stores the timestamp in one of the files. I've been looking around and saw this example:
awk 'FNR==NR{!a[$3]++;next }{ b[$3]++ }
END{
for(i in a){
for(k in b){
if (a[i]==1 && i ~ k ) { print i }
}
}
}' $FILE $FILE2
Which sorta works but its way over my head at the moment. The two files can be found in your /var/log/syslog and /var/log/auth.log (using Ubuntu 11.04)

Mar 18, 2010Samba seems to crash and come back after some seconds if I copy a lot of small files in a short period of time over the network. How do I fix it?
I have Ubuntu 9.10 Server 64bit running on a D945GCLF2 board sharing two 1TB ext4 formatted HDDs to my Windows PCs using samba. I've been having an issue with reading or writing files through samba. It happens during copying operations or checksumming, anything that reads or writes MANY small files in a small amount of time. I am pretty sure the problem has to do with my server because the server has run on two different LANs in different homes and will crash from activity with any of several other PCs. There is no crashing if I access the files through SSH, although when I do that the max transfer speed is less than 1MB/s.
When I induce the crashing, there is absolutely no output to the server terminal.
As an easy access example of something that will crash samba, extracting Cinebench R11.5 to the server will do the job. It always fails.
Ubuntu :: Pc Acting Slow When Reading / Writing Files From _ Onto Disk - Is That Normal?
Sep 27, 2010Whenever I am busy reading or writing large files, or large sum of files, my computer is unresponsive. Screens are getting greyed-out and I just can sit there and wait until the reading/writing is done.
This is not caused by the CPU which is overstressed because it is not. Look at the attachments and you will see the CPU is used for about 20%. When these pictures were captured the computer was using hellanzb to unrar a long list of rar-files.
When you look at my signature you see the computer is not bad at all, just disk-access is slow. I can transfer files with a maximum speed of 30MB/s. Is that normal or is it very slow? I don't know the numbers. I have 2 SATA disks.
O.S. is Mint 9-Isadora, based on Ubuntu 10.04 and I use the 64-bits version.
Debian :: Suid And Writing Files Permissions In The ET Server?
Feb 22, 2010I have tried to configure an Enemy Territory Server in an way that a common user could run it just executing a command line. The first thing I did was writing a script like that
/usr/local/games/enemy-territory/etded +set dedicated 1 +set net_port 27960 +set fs_game etpub +set fs_homepath /usr/local/games/enemy-territory/27960 +set sv_punkbuster 1 +set +exec server.cfg +set +exec punkbuster.cfg +set +exec bots.cfg
and then putting it in the /usr/local/bin directory. Ok, the things seem to be fine, but then I realized that the program tries to write some config and log files. I noticed that because some warnings appear in the command line, like that Couldn't write etconfig.cfg always that I run the command as a normal user. On the other hand, if I give writing permission to these files, all the warnings disapear.
But I don't think it is a good way, because someone could change these files by hand, what would not be good.
My last try was to set the suid of the script up, with the command chmod u+s /usr/local/bin/etded-server
But as I already knew that suid does not work well with shell script I wrote a C source like that:

General :: Writing Files From NFS Client To Server Behind Firewall ?
Jan 25, 2010For some time now, I'm having some problems with configuring an NFSv4 server to let it work with a firewall. I've already searched to web, but I was unable to find a solution that works for me.
The situation is as follows:
I'm trying to connect an NFS client to an NFS server that is behind a firewall. I don't have access to this firewall, but I can contact the administrator to open some ports for me. I already did this for opening port 2049.
The result is that the client can read files from the server, but is unable to write files to the server. I believe that for writing an extra RPC-connection needs to be set up. However, the ports on which the RPC-connection is set up, seem to be different for every connection (I verified this using 'netstat -tn').
Clearly, this is a problem since the server is protected by the firewall.
Thus, what I want to do is configure the server in such a way, that it always uses the same server-side port(s) to connect with the writing clients (just like 2049 for reading). I've already tried to configure the /etc/default/nfs-kernel-server and /etc/default/nfs-common files, but that hasn't really worked out yet.
Note: Because I don't like to contact the system admin every day, I hooked up 2 computers (client/server) on which I set up the same configuration (without the firewall). I'd like to see it working on those machines first (that is, 'netstat -tn' showing the correct port), before I contact the admin to open some extra ports.
General :: Writing Or Sending Files To CD Accomplished In Mandriva?

Linux does not offer this option in it's helper file and you can't click and drag a file in the CD folder. The dialog box reads "you do not have permission to write to this folder" when I try to drag it in and I can't change the permission signed in as Root.I don't have a clue. I wish Linux Questions would add a emotioncon that has the expression " what the hell buddy? are you on ten hits of acid?

View 2 Replies View RelatedUbuntu :: Comparing Multiple Files In Shell Script?
Jun 13, 2010I've got an interesting challenge for the shell scripting wizards here. I've got a mySQL dump of three files for my amarok database with the intention of copying some files to my media server (cover art) so that I can keep the server the server and not rely on my local machine.
Step 1: Identify any cover art files on my local machine.
I did this with:
Code:
mysql -u amarok -p amarok -e "SELECT * FROM images WHERE path like '%.kde%'" > cover_art.txt
Output looks like this:
[Code]....
What I have here now is the ENTIRE album list in my collection -- and something to compare the IDs in Step 1 against. I'm going to stop here and will update the thread as I get past this stumbling block. "ID" in cover_art.txt = "image" in albums.txt... straightforward enough, right?
So the question is this: how do I create a simple shell script that will loop through the IDs in cover_art.txt (i.e. characters 0 -> 4 -- it will always be a 4 digit ID) and then search for that ID in the Albums.txt file.
