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.
View 6 RepliesI'm trying to write a init.d script to daemonise a sagemath notebook server. Here's what I've done so far, I've copied /etc/init.d/single for the structure, and tried to use dtach to provide a handle to access the process. However, my main problem is issuing the signals to kill the process (Ctrl-C) from a bash script and exit dtach (Ctrl-`)

My 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.
" Mark the start of the text with "v", "V" or CTRL-V. The character under the cursor will be used as the start.""With CTRL-V (blockwise Visual mode) the highlighted text will be a rectanglebetween start position and the cursor."I can mark the start with "v" or "V".But it doesn't work when I push ctrl+V.

But I found that even after reboot, I'm still stuck with TTY. I clicked Ctrl Alt F7 but still it's a terminal and it did not return to the GUI or the normal desktop. What will I do to exit it? It's a good thing I have windows vista along with it or else I'll now have a computer that I can't use outside the terminal.

My server pretty often becomes full up php processes running which are not needed. Is there a way to search for and kill any php process that is more than 3 hours old?
View 7 Replies View RelatedCtrl-c doesn't always work to kill the current process (for instance, if that process is busy in certain network operations). In that case, you just see "^C" by your cursor, and can't do much else.What's the easiest way to force that process to die now without losing my terminal?
Summary of answers below:Usually, you can Ctrl-z to put the process to sleep, and then do "kill -9 process-pid", where you find the process's pid with 'ps' and other tools.On Bash (and possibly other shells) you can do "kill -9 %1" (or '%N' in general) which is easier. If Ctrl-z doesn't work, you'll have to open another terminal and kill from there.

It does not say that my password is incorrect, just asks me log in as if the previous exchange never happened.

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
