Mar 23, 2011I'm playing with perl and found that I could just go:

General :: Executable File Apparently Doesn't Exist When Trying To Execute With Bash
May 9, 2011I downloaded a program called tonespace http://www.mucoder.net/en/tonespace/ which I extracted and then tried to execute the executable file with ./tonespace. This gives me the following message:
bash: ./tonespace: No such file or directory
When I use the command: file ./tonespace I get this: tonespace: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, stripped
I dont get it. The file is clearly there, yet when trying to execute it bash doesn't seem to recognize it.
It has permissions rwxr-xr-x and is not owned by root. Am I overlooking something?
General :: Kill Bash Processes "nicely"?
Dec 15, 2010I'm trying to avoid kill -9 for the reasons described in the Useless Use of Kill -9 form letter. Is this function sufficient, or do I need to kill the kill processes after a timeout or take care of other subtleties?
soft_kill()
{
# Try to avoid forcing a kill
# @param $1: PID
kill $1 || kill -INT $1 || kill -HUP $1 ||
(echo "Could not kill $1" >&2; kill -KILL $1)
}
As an aside, what's a better name for this function? The current name reminds me of "Killing Me Softly", and manslaughter sounds a bit severe. Maybe spoon_kill (Google it)?

Jan 14, 2011i am using putty to connect to the linux server and i am using nano as my text editor to write a bash script.

Mar 24, 2011I am trying to process a column separated data file, with a few bash command. For example, I have
Code:
file1 aaaa yes
file2 aaaa no
file3 bbbb yes
Let say I want to create new file with the output of first column and do something else with the output of 3rd column. Of course there are many ways to process this data file, but I wish to know by using awk, how could I do it. I'm trying:
Code:
awk '{system("touch $1")}' datafile
but the shell command will not able to get the awk '$1' output. How do I get this done ? And for another question, if the data file contains the variable name of a shell variable, how could I make use of it during a awk output ? For example I have a datafile1:
Code:
server1 yes
server2 no
And in another server declaration data file, I got this datafile2:
Code:
server1=xxx1
server2=yyy1
And in my awk script, I want to achieve something like (the syntax is definitely wrong, just to demonstrate what I assume it will like):

Ubuntu :: Execute Bash Script After Running Process Finishes?
Jul 28, 2011I have a computation going which takes a long, but uncertain, amount of time. I have another computation which needs to be run, but _after_ the first one is done. I won't be at the computer at that time to manually start the new process. I've done some Googling, and I found how to delay execution by a specific amount of time (e.g. "start process x in exactly 8 minutes from now), but that isn't quite what I want to do. Essentially, I'd like to tell the shell, "When process #nnnn finishes running, then start process x". Is there a way to do this?

View 7 Replies View RelatedUbuntu Servers :: Apache - Execute A Bash Script That Uploads A File To Another Server Through A Website?
Sep 20, 2010I have a web server in my kitchen with apache running on it. Since the upload speed is quite low due to my isp I would like to execute a bash script that uploads a file to another server through a website (which is htaccess protected) The idea in general: Someone with access to my website browses through a folder, copies a file path to an input form and presses "upload". Rather than executing a bash script directly I could have a cron job running in background that finds the path and then uploads the file to the other server I have userspace on and is accessible via sftp/ssh. The file would be than erased later after a couple of days or so. That person would be able to access the file with higher speed some time later without logging in via ssh and doing all that manually.

Ubuntu :: BASH: Execute Next Command Until Another Command Succeed?
Mar 19, 2010I have a big bash script ,its goal is to download movie one by one . But I often get into a problem: if this script is executed in cron,it often does not completely download the movie.I often find the movies it downloaded are several KB while the movie is actually 20MB.So I think it is because it did not wait for finishing one task ,and jump to download another.So I want to know ,is there a way to force the bash script to wait until one movie downloaded completely and then start to download another movie ?

View 6 Replies View RelatedGeneral :: How To Monitor Some Processes
Apr 30, 2011I need to create a small list of processes in a monitor.conf file. A shell script needs to check the status of these processes and restart if they are down. This shell script needs to be run every couple of minutes.
The output of the shell script needs to be recorded in a log file.
So far I have created a blank monitor.conf file. I have gotten the shell script to automatically updated every couple of minutes The Shell script also sends some default test information to the log file.
how I go about doing this part ? A shell script needs to check the status of these processes and restart if they are down.
I have put in the conf file the below commands but I am not sure if this is right.
ps ax | grep httpd
ps ax | grep apache
I also dont know if the shell script should read from the conf file or if the conf file should send information to the shell script file.
