I am trying to write a python script which logs into a NetApp filer and fetches some data. I am using the telnetlib library. Filer does not take exit command. So it expects Control-D. How to send that via python script?

View 7 Replies View RelatedI noticed that if I have "exit" in a bash script file., e.g. script.sh,that when the word "exit" is reached, and the script file being executed is not in the PATH nvironment, i.e. ". script.sh", the whole konsole shell profile is exited! What gives here? Is there another command compatible to "exit" to prevent this, or will I just have the leave the "." part in the PATH enviroment, which is, to my understanding, is not recommended? I desire for a "goto" function in bash script files

is it possible to execute command and terminate session all in one phrase
something like this connect to server hostname and than execute command "ls" and than some command
ssh username"at"hostname ls "something"
without "something" this phrase connects to server and lists directory, I need something that after listing directory, terminates session.
I am trying to permanently integrate a windows network drive into my Ubuntu 11.04. I don't have Nautilus - I am using Rox Filer instead. I am trying to get this job done according to this link here (Method 2): [URL]. I want to integrate the network drive as described in Method 2, but I don't have Places->Network. Is there a way I could do this without Nautilus?

it could be very helpful (and decide my next move) to see the exit code as 0, 1, or 2 . the man page suggests the command exit code will specify if the message I get - "Cluster size is zero" (I think it is a "1")is a recoverable or fixable error by the utility. or is non-recoverable - a pretty nifty feature if I understand this right.

View 10 Replies View RelatedMy two doubts:
(i) In office i open many terminal windows when i start my day and in each terminal i keep on login as different users many times in a day to do some task, by the end of the day when i need to exit from all terminals in a safeway instead of directly closing it i need to execute exit command or CTRL+D many times to close a single terminal safely. Can anybody tell me a way to exit from each terminal in single go, is there any command to acheive this ? I wish if we had a command like exitall like in vi we have :qa command to close multiple files opened in single window. I hope friends you have got what i am asking for ?
(ii) I want a software for debugging shellscripts searched a lot but dint got it.
I write a script to read a file which is something like a pipe (or) queue , which shows the running status.In normal case, if i open this file with cat command, i have to use ctrl+c to exit this . What command shall i use to do the same inside a shell script ? I have tried ^C in my script , but it does not exit the process.

I am using a program that reads in data from a serial port and then sends that data out over a TCP connection. The problem I'm having is that the only way I know to exit the program is to do a 'kill PID', but doing this means the program doesn't go through the motions of closing the TCP connection properly so I have to wait some random period of time for the port to free itself or else when I try to start it back up it tells me that it can't bind to the specified port.The general structure of the program is as follows
Code:
int main(){
// initialize some stuff

I have this command in ksh:

I'm new to scripting and I have a trouble with if statement syntax. The code is: Code: #there is a diff command here, and it does what i want but#i wanna see 1 if the exit value of diff is 0, and otherwise i wanna see 0.#the problem is here: (syntax error near unexpected token "then")

i am wondering why the following simple code causes a segfault on exit,when the std::string destructor is called.

I guess the memset messes with some internal std::string's data structures/pointers. I personally am anti-memset,and always avoid them.

I have a problem with the last point of some homework I have for an OS class. I need the program to print the pid upon execution, then for 10 seconds react to SIGUSR1, SIGUSR2 and SIGTERM. If either USR1 or USR2 is received, the 10 seconds are reset. Some of the functions I'm told to use are alarm(), pause() and signal(). The nicest way I found was to handle SIGUSR1, SIGUSR2 and SIGALRM in the parent process, with SIGALRM killing the child (with a SIGTERM). In the child a pause() (or for(; pause() would be enough for it to be alive until killed from the SIGALRM handler in the parent.
What I found is that I can't just do a wait() in the parent process, waiting for the child to be killed, since whenever the parent receives a SIGUSR1 or SIGUSR2, the right handler is called but the child exits nicely. I tried blocking/ignoring those signals in the child, since the default behaviour for SIGUSR1 and SIGUSR2 is to terminate the process, but the result is the same. The only way I could do it is using a waitpid() within a do { } while(!WIFSIGNALED(status)) since when the child gets killed with the parent's kill(), it's WIFSIGNALED, whereas when it exits after the parent handles a SIGUSR1/2, it's WIFEXITED.
P.S. What I'm doing to achieve the expected 10s window is calling alarm(10) in the parent process and again within the SIGUSR1/2 handlers. In the SIGALRM handler I kill the child and within the child I simply do a for(; pause()
I have a scenario where I am executing some child shell scripts in background (using &)through a master parent script.
Is there a way I can capture the exit status of each individual child script after the execution is completed.
It's called TextRipper and it creates indexable and editable text files from any image. Feel free to copy TextRipper; it's licenced under GPL. My troubles are with cracking passworded pdf's. (As you can see, I meant any when I said any image.)
I can't find a way for the user to cancel the decryption process by exiting the script without pdfcrack orphaning. Line 349 works the rest of the time; the concerned process is line 228. I believe it's a piping/subshell problem. At least that's how I've been going at it in vain.
I've made portability a priority and that the comments still require updating.
Code:
If the result is one output file, TextRipper will open it for you in OpenOffice Writer.
Otherwise all txt output files (editable and indexable) will be in the original file's directory." 0 0
I have not been able to write bash to use a PID file to ensure no other instance of the same script is running! All three methods I can think of to see if the PID in the PID file is another instance of the script make the script exit with a return code of 1 but the same commands run at the command prompt work as expected.
The first attempt was:

The first attempted workaround was:

The second attempted workaround (with debug to make the following command prompt copy and paste meaningful) was:

Here's the command prompt session, testing with a stale PID file and then manually running the problem command and it behaving as expected:

In desperation I tried rebooting but the behaviour was the same.
