Im writing a script that extracts part of the path name:I drop a file in terminal and set the directory name of the file to x using dirname $0note: ( directory is different every time since not all files are from the same location)
ex.
x="/home/Downloads/yesterday/photo/.../image.png" /image.png
/.../ means I dont know the name of folders between but I know the path name always starts
[code]...
I've these path:
Code:
xxx/yyy/zzz/0908/aaa/a.txt
xxx/yyy/zzz/0909/aaa/a.txt
xxx/yyy/zzz/0910/aaa/a.txt
fff/ggg/hhh/iii/jjj/0911/aaa/a.txt
fff/ggg/hhh/kkk/0912/aaa/a.txt
and I would like to extract only the number, so that I've get the result
Code:
0908
0909
0910
0911
0911

I want to record an internet radio station starting at 2:00am tomorrow morning. The specific program on the radio station lasts until 6:00am. The command I need to run to record the station is: Code:mplayer http://wjcu.jcu.edu:8001/listen.pls -ao pcm:file=indie_heat_of_the_night.wav -vc dummy -vo nullI'd use cron, but 1. I'm not sure how to and 2. it seems unnecessarily complicated for something that I only want to run once. If cron is the only/easiest solution, I guess I'll just have to resort to that, but I'd rather not.

View 2 Replies View RelatedSo right now VNC is starting a session using :1. When I connect to that session, the terminal is logged in as root. I'd like for the terminal to be logged in as a different user as some of my end users are going to be using this and don't require such privileges. I found that I can "su" to a different user and start a new VNC daemon on :2 and when I connect to that session, the terminal is logged in as that user. What I want to do is get that to run at boot-up.
View 4 Replies View RelatedI deleted some files on the command line and would like to learn if it's possible to recover them. It's not a terrible thing if they are gone, but I want to see what I can do. The server is configured as a hardware RAID5+1 (ext3, Debian Stable) and I *really* don't want to take a dd of the entire disk.
ls -id gets me the inode value of the directory(155655)
I'd like to create a disk image starting at that specific inode. Then there is the issue of picking an outer boundary of the disk image. I'm hoping there's a dd/ext3 genius out there to advise.
I am trying to zip a directory but when I zip and unzip it, it contains the whole path of the variable "album". I would just like to zip the last folder in the path. Here is what I have now. I tried basename but that didn't seem to work, possible I just can't make it work right.

how to extract only this mail from /var/mail/root
I need to search a bunch of files in a specific folder for a specific number and add all the numbers together to a total sum. I use Rsync everyday, everytime I run rsync i get a logfile (rsync output) witch contains the textstring "Total bytes sent: xxxxxx".
The "xxxxx" can vary in lenght. I need to extract the "xxxxxx" from each file and add the numbers together to a total size over a week or a month. Is this possible? And I wish to only use bash. One way of doing stuff at a time my friends .
A function by name abc is called in many files. I want to copy all the lines with the function call to an output file.A simple grep on function name doesn't help me as the function call is spanning across multiple lines as follows:
abc(parameter1,
parameter2,
parameter3);
So I want to copy all the three lines (till semicolon) to the output file.The problem is because there are more than 200 calls for the same function and I cannot do it manually

Elsewhere is my question about 11.3. I have had to abandon that and 11.3 as my RAM is too small. Now, for the first time in many years, I find it necessary to extract specific data from received .pdf files. According to OpenOffice, editing of these files is only possible from version 3.2. My concern is whether this later vesion will be compatible with 11.2.OpenOffice installed is 3.1.1.4-1.1.4-i586. The same question has been directed to their Forum.

Is this possible, or is there a better way to go about this?

I am using secure delete to remove files from a Debian Linux PC. However, secure delete does not remove folders. This has lead me to look at writing a script that would move files to a predetermined folder for deletion. My plan is as follows:I have a folder on my desktop called shredder where I move the contents of the waste bin to. The script needs to identify all files within the folders and sub folders, within the shredder folder, and move each file to the shredder folder and then delete the folder. At this point secure delete can be used with a command like shred -v -u *.*on the shredder folder.The problem I have is in creating the code to move files from the different folders and then deleting the folders. Note that the names of the files, folders and subfolders will not always be known
View 12 Replies View RelatedMany years ago, I converted a portion of my files to an arbitrary format with a specific extension. i no longer desire to have them in this format and i would like begin the process of replacing them because conversion is not an appropriate solution. unfortunately, they are mixed in separate folders of the same root folder with files in my current format of a different extension. I feel it would make this process easier if I were to move every folder that contained a file with the undesired format to a separate root folder. The files are stored on a Linux server and shared via samba. How can I do this with a couple of commands or a script? I am open to other suggestions as well. I want to avoid time spent editing text files. Ultimately, I'd like a command that produced a list of full paths for folders, sorted by the number of levels would be a nice touch. A list of all of the files is clearly not what I'm looking for.

Currently I have 5 HID's I would like to use on the system at any given time. However, I have the problem of them using different device paths depending on what order I plug them in... Which wreaks havoc on qjoypad and also my music software which looks for a specific device number, which may or may not be the same as it was last time.
For example, I have 2 rock band drum controllers which I use to send MIDI signals. I need them always assigned to the same device path, so that I don't have to change the settings in my music software every time I run it, to make sure it's looking at the right controller
Or if I am going to play games with a gamepad, but I also have the drums hooked up, the gamepad may be assigned to /dev/input/js2, so I create my qjoypad profile.... Let's say the next day I reboot with the drums not plugged in, the gamepad is now /dev/input/js0, and the qjoypad profile won't work because it is looking for that gamepad at /dev/input/js2... So I would either have to create a new profile, or hook the drums back up in the same order ... Or something
It's just a mess...
Is there any way to tell Ubuntu to say "/dev/input/js0 is always Playstation gamepad", "/dev/input/js1 is always drum pad 1", etc.?
Or some way to do away with /dev/input scheme altogether and somehow link directly to the name of the device?

View 1 Replies View RelatedI have a workstation dedicated to monitoring. The goal is to have multiple web sessions and other applications running across dual screens on multiple virtual desktops. I have a nice Perl/TK/wmctrl script that will automatically rotate the desktops. All is working great.
The problem is, I need a solution to automatically start the applications on the correct desktop, with the correct window size, in the correct location on the desktop. That way we can start the monitor boxes in the morning and have everything start in the correct place. It is a really cool effect to have wall mounted monitors with cube rotation showing off multiple graphs and more.
Do any of you pros know how to start an application with a specific window size and define where on the desktop it is placed? The box is running OpenSUSE 11.4 KDE. Is that kind of control possible?
