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();
I tried to execute a shell command by M-! cmd RET but it did not work.M-! does not turn up in the microbuffer no matter how many times I press Alt+!.But if I go to Tools menu and select Shell Command... option then it writes M-! to the microbuffer and everything works fine.What is the problem here?
I need to execute an external command with Python from Web. I know there is subprocess module that executes external programs but I'm trying to execute a command registered for the execution of a program. In this case when I execute my file in the shell everything is Ok, but from the Web it doesn't work.
A colleague gave me a shell script ("dti_motion") which needs to be run from the directory containing all the files it works on. I want to run the same script for several different directories. But I don't want to have to cd into each directory, run the script, wait for it to finish, and then cd to the next directory (there are 52 to do altogether).
So I wanted to write a very simple script that will cd to each directory and perform the script there, before going on to the next one. My colleague's script ("dti_motion") is stored in my home/bin/ and is executable. My home/bin/ is in my path, as verified by echo $path. When run from a directory containing the necessary information, the dti_motion script works perfectly well. I wrote an extremely inelegant script called "dti_motion_do_all" which is also stored in my home/bin/ and executable:
#!/bin/sh #Get motion information for each subject, using Mark's script, called dti_motion cd /imaging/cr01/PD_DTI/C_10/12x5
[code]....
I know there will be more elegant ways to write this script with loops, rather than simply using cd, but for the moment, I just want this to run, until I have learnt to use loops properly. how to correct either of those "command not found" or "no such file or directory" errors, given that both the original dti_motion and my dti_motion_do_all script are in my /home/bin/ (which is on my path) and both scripts are executable?
I'm developing a Servlet which when it gets a request, it has to execute a command. I've tried in Windows and it works fine, but when I "install" my web app in Linux, if I try to execute the commands I get permission error.
An example of one command I'm trying to execute is: Runtime.getRuntime.exec("rm file_name"); -> This commands outputs that I don't have permissions.
If I add "su" before the command, how do I add the password?

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
I have this scenario, where in I'm calling a shell script inside another shell script. The only criteria here is that the embedded script will have 654 permissions and the master script should be able to execute this embedded script. The sample code is given below:
The test.ksh which has 654 permissions is called by the main.ksh script and when I try to run it using ./main.ksh, it fails with the error "Execute permissions denied."
when I execute the command from the shell command line - it works and no error code.if I do the exact same command from a perl file - it fails with code 32512.the file is created from the same perl script that runs the command that fails. file permission is 0664.
How can we fire a shell command like ls,./a.out automatically in kernel space via a kernel module ? i.e. replacement of system() function of user space into kernel space.We need to develop a kernel module which can fire some shell command let say "firefox [url]" automatically to open google automatically from module.
If say, I want to read the input given by user at the command prompt and write a code to execute the cmd given then which commands do i use to implement this ( Im writing the code in C )?
Does anyone know a method of being able to process the complete and literal command line passed to a shell script ? I want to have the command line parameters with ALL characters (including meta characters e.g. $ literally).
So as if there was no shell to substitute or expand parameters nor applying it quoting rules.
I have written the following script in my linux server to add users for LDAP database.But i can't able to run this.
The script is as following
#!/bin/bash echo "Mention the username which you want to convert LDIF format" read username if ["$username" -e "/ldiffile/passwd"]; then echo "Username already exists" else cat /etc/passwd | grep -i "$username" >> /ldiffile/passwd fi The output which i got : . ldapadd.sh Mention the username which you want to convert LDIF format yal2361 -bash: [yal2361: command not found
I've been looking around the net for executing a shell script. My basic understanding is that after setting executable permissions and providing a path (#!/bin/sh) in the first line of the script, I can type ./myscript to execute instead of sh myscript. This is not working for me. I can run "sh myscript" but not "./myscript" even though I know for sure I have across the board execute permission and my sh path is correct. I'm working on a redhat linux station.
I wonder if there is anyway to make a user-defined bash shell function global, meaning the function can be use in any bash shell scripts, interactively or not. This is what I attempted:
I am trying to fix a perl script, and I really suck at perl. But I think this problem will be easy for people who know it.
The problem is, I have an old setup script someone wrote many years ago. It fails if the standard shell is dash and not bash. The only way I've gotten it to work is to point /bin/sh to bash. I looked thru the script and it uses "system" many places, and I think that's the problem.
I searched for it and found this link:url
My plan is to include this function:
Code: sub system_bash { my @args = ( "bash", "-c", shift ); system(@args); } Then I could simply change all calls to system into system_bash and it should work?
The parameter to the system calls is usually some variable. What if the parameter is a list already? Do I need to test for it somehow, and if it's a list, prepend "bash" and "-c" to the list? How do I do that?
In the script there are lots of places like this:
my $error = system($cmd); if ($error) { die/warn "some error message"; }
Shouldn't there be a return in the system_bash function?
Trying to create a small script that will read user's input, test if user entered some input and if not display some message or display a text using user's input.
The script is the following but i get an error saying "[: 6: =: argument expected"
I have a some c source code files that i have to copy to linux machine from a windows machine over a network. This source code folder has to be copied into a particular directory structure in the linux system at the other end. After copying the file into the appropriate folder in the linux server i have to instruct the linux machine to make(using the make file that is there with the c files) this source code from the windows machine. Does anyone have any idea in regard to how this can be implemented?? i am trying to have a gui client that has the above mentioned options(copying and inserting the c files into the appropriate directory and then for making the files and getting the executable.)
im searching for this answer now a pretty long time and i know that many similar questions where asked and i all looked themIm trying to run a the command "vncserver" on our opensuse11.2 server when its booted.many posts here endet in "put a sh script into your /kde4/Autostart" but that didtn help for me because the server runs without a screen and normally nobody is logged in. When i logged in that worked fine.i also tried to add the command "vncserver" to "/etc/init.d/boot.local " but that didnt work too. i think its to early executed to work.i also tried to activate the service to start up at boot with chkconfig vncserver start but the service vncserver is "unknown". when i type vncserver into the console after logging in everything is alright.you see i really tried a lot and searched a long time at google and in this forum but nothing worked
