I have a program I use, rrdtool. I need to modify a ds value on every file at the same time. However, using a wildcard (*) to try this operation of all files does not work and instead only updates one file.
Here is the command syntax:
rrdtool tune <file> --maximum traffic_in:100000000000 && rrdtool tune <file> --maximum traffic_out:100000000000
So, how can I do this on every file in the directory?
The output of a command changed and I need to extract the data and print it out in a different fassion:

should be transformed to:

Currently I used sed "search1|search2|search3" to get the lines that need to be transformed. But I also need to search for substrings in those lines and I need to print those substrings in a specific order together with other characters. How is this done with sed?

Prior to upgrading some of my hardware I had 4 drives used just as storage. Now I'm trying to mount the drives as an LVM but I don't have enough slots to connect all the drives at once now b/c they use an outdated type of cable. I can connect three of the four. So, can I somehow move these to a new group, or remove the missing drive from the existing group?The error is:Couldn't read all logical volumes for volume group VolGroup.Couldn't find device with uuid 'yQtrVB-5jCk-vF10-05c2-AcDL-GNn1-ivdxxh'.

I was installing a software in my Ubuntu 9.10 and after installation completed it prompted the following warning:
Warning: Your PATH does not point to your newly installed /home/pc/Reflex/software/bin/esorex.
To ensure execution of the newly installed software you should modify your PATH.
Note that "esorex" is the executable file and by typing its name in the Terminal the program starts.
What should I write in my "bashrc" as PATH to that program?
If I want to modify my .bashrc file to change the HISTSIZE would the following command be for example; HISTSIZE=200? And if I want to change the DEBUG_LEVEL to 8 would the following command be; DEBUG_LEVEL=8?

how to modify (or get rid of) the sound (music) that is played when the computer starts ? (with ubuntu).
View 5 Replies View RelatedI want to modify a file like /etc/gdm/custom.conf from the shell or a script.
# GDM configuration storage
[xdmcp]
[debug]
[daemon]
AutomaticLoginEnable=true;

But the idea is that I can add a line to a section and it check if the section is defined, (add the definition if not), the property is defined, let it undefine (erase the line), (and delete the section header if there is no property defined), etc...
I didn't find anything except gconftool-2 but it do not explain how to modify other files. (there is a shema file there).
there isn't a program/script to achieve this, but can easyly be made for every config file, If someone do something like that, with a little database of which markup use each file, it could become really popular.
