I want to check weather a for loop has executed properly
Code:
for name in `awk -F: '{printf " "$1}' /etc/passwd`;do
echo $name;done
[ $? -eq 0 ] && echo "SUCCESS" || echo "Failed_to_fetch_the_user";
Every time this gives output as SUCESS even If I change /etc/passwd to other file name.
How can I resolve this ?
I've got a fairly complex bit of code (a for loop within a for loop) which I'm trying to execute remotely, however because of the special characters this exits without making the connection.Usually I'd do:ssh root@ipaddress "for i in `cat /etc/hosts | awk '{print $2}'`; do ping $i; done;"But given the complexity of my code this usual tactic doesn't work

My DVD/CD burner is rather old now (going on 5 years), and I've had some "quality" issues when I've been burning stuff for the past year.
CD's: When I play a burned CD in my car stereo, the songs have a "skipping" sound to them on the low-volume levels of the audio. I use K3b as my burning software, and it seems to be the best, but am I wrong? Is this a common problem?
DVD's: Specifically video DVD's. After converting the .avi to an image file using DeVeDe Creator, it gives me a file that has the .iso and I burn the disc using K3b. It's really hit or miss.
The question: is there a way to test the performance of my DVD burner to make sure it's working properly? Is there a way to calibrate the mechanism? I have a new External DVD/CD burner that supports "LiteScribe" (I could be mistaken on the name, but it's a technology that allows you to create a picture on the opposite side of the disc), but my INTERNAL is a 5 year old Lite-On.

View 1 Replies View RelatedI have a script scheduled to run with Crontab at 5am each weekday.The script is all good and executes manually (is just a simple stop/start of a service)I have reason to believe that it is not executing according to schedule.I am looking to see when a script was last executed.The script is executing accordingly (long story short, I forgot it was Tuesday). I would still like to know how to check a last-execution time.

View 14 Replies View Relatedwhy a script is not being executed during shutdown. I have a script in 'init.d' that works properly from command line. It also works fine at boot. My problem is that it does not execute at all on shutdown. I am using all the standard rc.d stuff for the script. Here are my LSB tags:
Code:
### BEGIN INIT INFO
# Provides: setwebpage
# Required-Start: $network httpd
[code]....
When I check the rc?.d directories, the appropriate links are there with the proper NN. This script has to FTP a couple of files to a remote server so the network is required and the script should be run very early in the shutdown process. However, the first thing the script does is send a message via 'logger' indicating it is executing with the 'start' or 'stop' parameter. The 'stop' message never shows up in the log thus I have to conclude that it simply is never executed.
I have a .wav file that ask "what's is your name in a robotic/computer voice. Is there I way I can execute that .wav file to execute as the script itself ask "What is your name?" giving the illusion that the computer is asking the question?

I use KeePass2 to access username/password information in a Dropbox file. This allows convenient access from multiple devices. I can't seem to copy a password to the clipboard on my Linux 2.6.27.41-170.2.117.fc10.x86_64 system, however, in order to supply the password to a prompt in an xterm(1). I've tried both Ctrl+C/Ctrl+V and highlighting and mouse button 2 clicking. The KeePass2 program on the Linux system is executed by Mono.
How can I copy the password to the xterm(1)?
[Aside: I think we need a "KeePass" tag.]
