Is it possible to have an Expect script spawn an SSH session, log in, then go into interactive mode and give control of the SSH session to a Bash script? Here's a simplified example of the script so far:
Code:
#!/bin/bash
expect -c "
[code]....
I have this expect process:
Code:
spawn -noecho telnet my.host.com
expect {
[code]...
I want to spawn a GDB session from bash script and keep it working to interact it from outside. But when I start it in background (with '&' sigil).
Code: gdb -x gdb_script.txt ./a.out < gdb_pipe.fifo &
It executes passed script and terminates by itself (I do not pass any data or signals to it)
Code: Breakpoint 33, main (argc=1, argv=0xbffff0f4) at main.c:53
---Type <return> to continue, or q <return> to quit---53
read_main_config();
(gdb) quit
A debugging session is active.
Inferior 1 [process 5957] will be killed.
Quit anyway? (y or n) [answered Y; input not from terminal] What can I do to make it alive?
I'm using expect to log into a remote server and run a script. I want to able to have expect edit the output from that script, on the remote server, in VI. Has anyone ever done this before, it seems as though the expect interpreter has nothing to expect once VI is started, the file pointer starts at the beginning of the line, and expect usually reads the characters before the pointer.
spawn ssh user1@$remote_server
expect "password: "
send "$password
[code]....
I have a program that I run from the terminal that requires manual input (it's matlab in mex debugging mode, matlab -Dgdb, which starts the GNU C debugger with its own custom settings).
Every time I run this program I always type in the same few commands in the program's interactive shell before I actually start working (for example: run -nojvm; stop at mexFunction; continue). I want to avoid typing these commands and I thought I could do this with shell scripting, saving the commands in the mycommands file, then running: myprogram < mycommands
The problem is that this runs all the commands and then exits the program. I want it to run the commands and return control to me so I can run my commands. Is there a way to tell the shell to use a file or a string as the input to a program then immediately return control to the user without the exiting the program?
I am using pthread_create system call to create a thread. However pthread_create does not return the PID ( process ID). Is there any quick way to fınd the PID of the created thread.

from paul's reply in the link (http://www.linuxquestions.org/questi...c-code-181152/) , I am trying to retrieve the count from a shell script using option 1: below is the system call that I have used to call my shell script named "test"
Code:
#include <stdio.h>
#include <stdlib.h>
int main()
{
int i;
i=system("./test 1234");
[Code]...
Here "test" is the shell script that is fetching the count from a table for a particular column("1234") that I am passing as the parameter. When the "test" script alone is run, it is returning the correct count but when trying to check through the C program it's returning some different value. How can I get the exact value from the script in my program above?
I am trying to make a script that can be used to check server load on a remote server and produces sound on our local machine, when server load exceeds a particular limit.1. I want to execute command uptime or uptime | awk '{print$10}'on the remote server and store the result in a variable(say x), and later use it in the bash script.

#!/bin/bash
x=$(/root/Desktop/exp)

I need to control daemons like dhcp/bind from within a perl script. I could run the script as root to restart/stop/start the daemons however, this is not good for security.
What are the ways of controlling processes within perl as different users?
Do you know how to write a shell script that executes say 4 instances of the same program in different directories at the same time, and once ONE instance completes it executes a new instance of that program in a new directoryd so on, until 100 instances have been executed, each in their own directory

View 1 Replies View RelatedI'm building a Linux From Scratch system and partially automating it. I will likely want to do it again, and I would like to try to almost completely automate it.
My current approach is a script that takes an input file and sequentially runs each line in a new instance of bash. If one fails, it gives me the number of the step that failed so that I can use the "--step" option to resume after I fixed the issue.
This has some problems:
A varible created on one line will not be accessible on the next line. This is because each line is run in a separate shell (the reason for this is so that the commands in the input file and the script's internal variables can't interfere). You can't switch users or use chroot, again because each line is run in a separate shell.
What would be nice is to be able to start a bash process in the background and send commands to its stdin. I guess that a named pipe would work, but the named pipe will be gone after a chroot. Is there a way to do it without relying on the filesystem? Also, how do I know if the command failed?
I use tcl-expect script to ssh to the server. How can I eliminate the first 2 lines if using system(./script.sh) to execute it, as the default output will be shown on shell and the first 2 lines are included.
Essentially I just want to have the "ps" result, not the login process. code...
I need to open a telnet session using a shell script that follows this format:
telnet 10.100.0.1
expect "Password:"
send <password>

send "pen" (till the end of lines generated as in |more.... usually we use like 8 space bar buttons after "pen" to generate all)
and I want to redirect the whole generated result of "pen" to results.
I'm really new here this is the first try to get some knowledge here.I have a littele question."echo {1,2}" does expands 1 and 2.so does "echo "`echo {1,2}`"".But when I do it with double quotes which is "echo "{1,2}"" it doesn't expand at all.why does this happen? I have read man for bash but could not get any clue.

View 3 Replies View RelatedI have a script in /etc/rc.d/init.d named foo. I want to start/stop/restart my process as follows:$ foo start But I do not see the [OK] message once it starts. There is no shell prompt returned either. It seems that my own process is the problem. The executable that foo calls is built from this sample code:
int main()
{
do {
printf("Hello world
");
sleep(1);
} while (1);
}
Do I have to return some kind of signal handle for this to work?
my code is very simple:
int pid, status;
printf("parent process id=%d, to call fork
",getpid());
if(pid=fork()<0)
[Code].....
but everytime I can only get two fork return pid=0. In parent process, the pid returned by fork() should be >0 and equal to the child process id.

View 1 Replies View RelatedI am writing an expect script. At a certain point there is a rule that produces this debugging output:
Code:
expect: does " Address or name of remote host [x.x.x.x]? " (spawn_id exp8) match glob pattern " Address or name of remote host [x.x.x.x]? "? no This just times out When I use -exact for the expect keyword it does work What am I doing wrong? THe first should also match in my opinion because it is equal as well. Even if I remove the I still have the same issue if I try without -exact. I don't understand. I tried removing the but still got the same.

I'm currently on a Linux machine and the shell prompt is showing me the last return value and number of executed commands (picture included, with these numbers shown in purple).
My own computer doesn't have this, how can I configure it? I'm using Xubunto, if more details are needed let me know -- I'm not much of a Linux user (I don't know what's relevant here).
I'm trying to create a super simple shell script, but I cant get a return line. The shell script looks like this (only the part that matters)
Code:
yes '' | ssh-keygen
The idea being it will put in a blank char. Then enter until the program finishes. The problem is, it only does the first time, the next 2 times I have to hit enter, it requires me to input it manually (which is exactly what I'm trying to avoid).
The full script (if you care):
Code:
#!/bin/sh
# Created by Omega
# First, program creates RSA key, named id_rsa and id_rsa.pub
# Second, program send the public code to requsted server.
echo 'Removing old id_rsa key (if applicable)'
rm -rf ~/.ssh/id_rsa.pub
rm -rf ~/.ssh/id_rsa
echo "Creating RSA key"
yes '' | ssh-keygen
# Checking if ssh-kkeygen created requested file
if [ -e ~/.ssh/id_rsa.pub ]
then
echo 'Done'
echo 'Username and Server in: me@server format'
read var1
echo 'Port Number? If standard put 22'
read var2
ssh-copy-id -i ~/.ssh/id_rsa.pub "-p $var2 $var"
else
echo ''
echo 'ERROR, ssh-keygen did not execute correctly'
echo 'Retrying...'
echo ''
echo 'Please leave all options default (just press enter)'
ssh-keygen
if [ -e ~/.ssh/id_rsa.pub ]
then
echo 'Done'
echo 'Username and Server in: me@server format'
read var1
echo 'Port Number? If standard put 22'
read var2

I wrote an expect script that tests user authentication against a RADIUS server. The username is an email address, including an @ sign. I recently wrote an HTML/PHP front end to allow others to input username/password into a form and then see the results when they hit submit. Expect code that takes two args username, and password
Code:
expect "#"
send "test aaa group radius [lindex $argv 0] [lindex $argv 1] new-code
"expect "#"
[code]....
Every works as it's supposed to, except for the output of the script. When it displays on the webpage, it's segmented weirdly with all throughout. What I've found is when I remove the @ sign in the username input, it fixes it. Is there any part of HTML or PHP that treats the @ as a special character? 1 more thing is that I have another HTML/PHP/EXP script that works fine with the @.
