Programming :: Execute A Shell Script (with Source Command)?

Nov 19, 2010

This is weird. I have a shell script with no execute rights.$ chmod -x test.shThen I try$ test.shwhich does not work. (I have "." in PATH)When I do$ . test.shit works! I can run the script even though I have no execute rights. Why is that?Another question: If I have a shell script without a hash bang, I still can execute the shell script. Why? What does hash bang do? If there is no hash bang, why is the shell script run? What does the hash bang do

General :: Execute A Command When Power Source Changes

May 20, 2010

My laptop has a dead battery. Even when it's fully charged, if the power cable is pulled out it only lasts for about 4 minutes before it dies. I'm running Ubuntu Lucid Lynx 32-Bit. What I want to do is create some sort of script or program that will immediately set my computer to go into hibernation once it detects that the power cable has gone dead. I'm willing to look into all ways of doing this. I can program in C, but I'm not familiar with the API used to manage Power Management in Linux.

Programming :: Unable To Execute A 4GE File In Ksh Shell ?

Apr 7, 2010

I am trying to execute a 4GE file using command something like this "/usr/bin/ksh path of the file with some arguments " ex: /usr/bin/ksh /home/abc.4ge S "./xyz" . I am able to execute the 4GE without this "/usr/bin/ksh" specifying in the command which basically runs in ksh shell itself. But when i try to run it exclusively using the path of the shell it gives me an error something like this "/usr/bin/ksh: /home/abc.4ge: cannot execute". I did check the permissions and all the file has execute permission.

Programming :: Getting Shell Script To Execute IF New Row In Postgres SQL Is Added?

Mar 17, 2009

I do not want to use cron.I want it to be instantaneous. I am working on a web server where the hosts turned-on safe mode and turned off a-lot of the functions for PHP (including exec) in order to secure their servers. Outside of that, I do have access to chroot and can pretty much do anything on the server. I want to use ImageMagick to create dynamic images based on form data.

I was trying to find a work-around with PHP where I can still use ImageMagick (a shell-based imagining program) by causing SQL to execute a shell script after the form data is saved to a table. Is there anyway it could cause a flag to automatically run a shell script when someone adds a new row to a certain table. It has to be instantaneous, more or less, so that the user isn't sitting there waiting for a minute for cron to catch any changes to the database.

Programming :: Effect Of Using Eval To Execute A Command As Opposed To Writing It On The Command-line?

Jun 18, 2010

Code: cmd='date | wc'

$cmd If this script is executed, an error is generated. The reason written was that "The execution fails because the pipe is not expanded and is passed to date as an argument".What is meant by expansion of pipe. When we execute date | wc on the command line, it goes fine.then | is not treated as an argument. Why?

Programming :: Using Bash Command To Execute Output Of Awk?

Mar 24, 2011

I 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):

Programming :: Source Or Dot Command Not Working In Makefile

Apr 5, 2010

I am trying to run a script to setup environment variables and then run other commands in a make file. But the source or the dot operator (shell is bash) does not seem to take any effect as the subsequent command didn't pick the environment up. Do I have to put every lines of the environment setup in the first script into the makefile instead?

sample setenv.sh
#!/bin/sh
export MYDIR=/somedir

sample makefile:

Programming :: Executing Shell Command In JSP

Aug 24, 2010

what we are trying to do is, to let the customer click a button in the web browser, and then the web server to call a shell script to do the work. The output from the stdout && stderr of the script should be displayed in the web browser once finished or timeout, along with the exit code of the script.

The shell script is however not on the web server, but on another app server. So to call this script from the web server as the identity 'tomcat':

Code:
$ sh appuser@app-server:$appbin/app-script

The .ssh/id_rsa.pub thing is done, and we have no problem doing this in the command line so far.

Our loaded ex-colleage has left us the webpages (jsp) with code like these:

Code:
<%@ include file="jsp_functions.jsp" %>
<%
String cmd = "sh $appbin/app-script";
ExecResult r = new ExecResult();
