Is there a way to delete files on the commandline that uses the KDE-Wastebin?It appears that I never ever need the KDE4 Wastebin for files that I deleted through Konqueror or Dolphin. It is only when I delete files on the konsole with rm that I wish I could undelete them. It always happens like that, mostly by being in the wrong directory or using a wildcard when I should not have. (I don't have any erroneous deleted file right now, and I do have plenty of backups, but I just wonder whether there is something better than rm to use generally on the commandline.)

I am currently reviewing what it means to switch over to Ubuntu and I have the following scenario. If I was to switch all the windows servers over to an Ubuntu solution. I already understand that file servers/ mail servers and resources can be provided Ubuntu 10.04. The issue comes with the user accounts access and control. In a windows environment, I have a domain with sub domain sites. I am able to control passwords in each site separately thought Active directory. I need the instructions on how to setup an LDAP server so that I can control access rights to different services located on different servers.
Example 1.
I have 5 mail servers and on the HR side, I have 2 email administrators. I wish to provide them access to only the relevant resources centrally. With out having to add users to different users repeatedly. For example, if I wanted to grant the two administrators access to all five servers. As I understand it, I would have to create the same user on every server and add a public key on every server, as well as set the administration rights for that user on each server individually.
I want to be capable of doing this like I am in a windows environment from some sort of domain controller equivalent. Things that I must be able to do, manage users public keys on each server centrally. Add and remove user's access to each server centrally. Finite control on what each user can do on each server. (i.e., add them to the sudo group or any other group for specific servers/server class I specify). To a lesser extent of requirement, I also need to be able to inform users they have to change there password every 3 months from when they change it. As well as enforce password rules, such as characters complication.
I want to write a shell script which will simultaneously collect OS user information and write in an individual text files.Can anyone tell me the syntax of the script.N.B. The user name will be mentioned in an array within the shell script.
View 8 Replies View RelatedA US ISP's "privacy" policy basically states that they will collect any and all of your data (email, posts, surfing etc ) and then "share" it". direct me to a "checklist" which can suggest counter measures for non-geeks? How can we function if we cant trust our ISP? Are there some specific 'tricks' in Ubutu to foil rogue ISPs? If yes, it would be a great 'selling point', especially for professionals concerned that rogue ISPs could "share" their intellectual property.

View 5 Replies View RelatedI'm trying to write a toy linux shell. For starters this is what I'm trying to do:
1. Start a new process with fork.
2. Execute a program in the new process with execl().
3. Redirect the output from the new process from STDOUT to another file descriptor, using dup2(2).
4. In the parent process, read the output from the child process and write it to the screen.
Creating a new process and executing a program in it is no problems, the problem is that I can't seem to capture the output from it in the parent process.

How do i get about doing it?
I have a number of text files throughout my /home/pjs/Documents directory tree that have execute permissions set. Almost all of my file names have spaces in them. I am trying to write a shell script that will look at each file in my Documents directory, find the ones that have execute permissions set, and run the command chmod 644. Of course, I don't want the command run on the directories.
The following script *doesn't work*, but might serve to illustrate what I am trying to do:
#!/bin/bash
for x in "$(ls -R)" do
if [ -f "$x" ] && [ -x $x ]; then
chmod 644 "$x"
fi
done
I want each file and directory name to be placed, one by one, in the variable $x, and then tested with the "if" conditionals.
The first problem seems to be that, although the command "ls -R" does produce a complete list of the files and directories I need, they are not placed, one by one, in the variable x like I want them to be.
Also, I think I should use the shift command so that the option -R doesn't get included as one of the values of the variable $x, but I can't figure out where to put it.
I write a shell script below to add a job to cron.
#!/bin/sh
touch date.cron
echo '*/3 * * * * /usr/sbin/ntpdate 192.168.2.3' >date.cron

Write some simple script?
Heres what Im trying to do:
-Qjackctl has a config file which is modified each time QjackCtl is shut down. This means that whatever preset is in use when QjackCtl closes is written into the QjackCtl config file as the DEFAULT PRESET, for the next time QjackCtl starts (or at least this is how I understand it).
-I want to edit a specific line in the QjackCtl.config file, which specifies the DEFAULT PRESET. Obviously its easy to do manually, but I want to do it using a shell script which runs automatically on StartUp so that QjackCtl starts every time with the same DEFAULT PRESET, NOT the last one used.
-Unfortunately Im not at my Linux system right now (which is KXStudio/Kubuntu), but I believe the QjackCtl.config line looks something like this: DEF_PRESET=alsa (where alsa is the name of the preset)
PRESET1=alsa
PRESET2=firewire
I want a shell script which changes the line DEF_PRESET=alsa to DEF_PRESET=alsa, even when it may currently exist as DEF_PRESET=firewire due to occasions when firewire was the active preset when Qjackctl was last closed. I notice that the application in KDE that enables the user to set which applications open automatically on StartUp also allows the user to select shell scripts.
Ive done some research, as a beginner, and Im led to believe I might need to use AWK and/or CHMOD. I could have a go at writing a shell script but Im always wary about experimenting with StartUp scripts/operations because obviously if I get it wrong and make my system unusable, then because its going to run first thing on each boot, Id have great difficulty disabling it.
