General :: How To Exit Out Of The Calling Shell Script
Aug 18, 2009
I have 2 shell scripts, script1.sh and script2.sh. I call script2.sh from within script1.sh ( by simple ./script2.sh command). Based on some condition, i use exit 0 to exit out of script2.sh. I was trying to find if i can exit out of script1.sh as well at once. below is the example
script1.sh
#!/bin/bash
echo "Before ..."
[code]....
When i execute below is the output
Before ...
There was problem file is empty
The Script will Exit. Please fix the issue and run again...
After ...
I am trying to exit out of script1.sh as well so that i dont print "After ..."
I am setting up a cron job, where i am calling a shell script to make few builds. I got struck at a point, need some expert inputs to proceed further. The script is categorized in 5 parts and in the last part while building software it asks for few questions like:-
User manually has to input ans for these questions:- 1 yes n 64
The ans's are fixed and this won't change. How shall i hard-code them or do something in the script so as when script flow reaches to this point it automatically take's these value. So far the cron job is not getting completed as it's waiting for user to key in these values manually. I had faced similar issue while building kernel modules but there it was easier as i had to take default values always:-
This is a very simple problem, but I'm scratching my head with others..
In composing a simple shell script in class, we can't seem to get the script to execute fully. script was formatted as follows.
#!/bin/bash echo "good bye for now" exit
did, Chmod 755 to make executable type file name "bye" runs but wont exit..... it just echos the type"good bye for now The instructor says it works for him at home.... But it wont work in class... Is there a reason it wont "exit" the shell as commanded ?
(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 need to execute a SQL via shell script and i am connecting to Oracle DB by this way $USERNAME1/$PASSWORD1@$STRING1 and i need to get username, password and string from someother file stored in the Unix Directory. $Username, $Password and $String is stored in File A in Path A and i want to call it in the test.sh in Path B.
Format of File A.txt Username=test_db Password=***** Instance=ORACLEDB
I am trying to call a script say mkdir.sh into another script that will make use of the dir's which are created in the first script. I know that I could code it all together, but I am trying to avoid rewriting the mkdir script as it is long.
I noticed that if I have "exit" in a bash script file., e.g. script.sh,that when the word "exit" is reached, and the script file being executed is not in the PATH nvironment, i.e. ". script.sh", the whole konsole shell profile is exited! What gives here? Is there another command compatible to "exit" to prevent this, or will I just have the leave the "." part in the PATH enviroment, which is, to my understanding, is not recommended? I desire for a "goto" function in bash script files
In linux, creating thread is same as process (clone()), except the virtual address space gets shared with the parent.If a running main process(thread) creates new thread, and if main thread exits, why should the new thread too exit? both are different entities, The same doesn't happen if the child thread exits, the parent thread would be alive.
how can you remove all the makefiles and whatnot and basically restore the source package to its original form after you've called "./configure" or even "make" ?
for instance you changed the source code then you ran ./configure then make then make install ....etc you checked the software and it functioned as you expected it does , now you want to remove all the makefiles and all that other jizz that you don't need or want anymore in the source (obviously in order to package it for distribution)
I have a script1.sh (see code below) which calls another script (which is a sort of template -> template.sh). But when i call template.sh i need to send an argument with it.
echo "$VAR files which are older than 1 hour in folder $dirpath" exit $exitstatus I geuss the command should look like something like this command
Code:
./script1.sh -d /
You don't have to look at the code of template.sh, thats not important. I just need to know how i get this to work I don't think it's that hard, but i just can't see it ...
I read somewhere that you should not be reading config space to determine the irq value to pass as the first argument to request_irq(). What is the proper way to determine the value of the 'irq' argument before calling this function? Hope this is the correct forum. I don't see one for drivers.
I am trying (desperately) to setup freeNX so that I can access my Mandriva box from my Macbook over my network. I have great need to be able to do this. Here's the necessary info for you: Mandriva PC: running Mandriva 2010.0 with freeNX installed from the Mandriva repos Macbook: running OS 10.4 with the Nomachine NX Client installed Now, I have followed the setup from the Mandriva wiki as well as the freenx wiki to no avail. I simply cannot connect the Macbook's NX client to the server. I get an authentication failed message. However, I can ssh from the Macbook to the server just fine (that's how I'm getting most of this work done).
Back when I was first learning Linux, one of the questions that I kept wondering about was "what are all these files and directories for?" I couldn't find a resource that would explain them in a digestible manner. Specifically, I was looking for one that would allow me to look at a Linux filesystem interactively, collapsing and expanding folders to look at just the ones I was interested in at the moment. So later, when I got the opportunity, I wrote it.
But despite a ton of research, I'm still not totally knowledgeable on the subject. The most important thing I'm looking for right now is for experienced Linux/Unix people to tell me where I got stuff wrong, and for newbies to tell me how useful it is to them and which things need clarification. I'm also interested in technical and graphical ways to improve usability, like better icons, layout, etc. I know I need to be able to collapse long descriptions, but what would you like to see? The Works Cited list and a full introduction are still on the way as of this writing.
Without further ado: Linux Filesystem Hierarchy Explanation. You'll need a fairly recent browser that can handle XSLT; the actual info is stored as XML, and transformed into HTML with an XSLT stylesheet. This is still a work in progress, and I'll be updating it as the thread progresses.
Finally, would people be interested in collaborating with me on this, as an open-source project? I've never done anything like that, and I'm not sure how much time I'll be able to give it in the future, but I really think this should be continued and expanded.
Edit: Works Cited and decent intro are now in place.

When I run my script(attachment) and I use an option(-l -u -r) that requires an argument, it should exit if the argument isn't supplied, but it doesn't. How do I arrange this?
I am wondering if I can open a shell or new terminal thing from within the terminal in a unix/linux enviroment. Particularly a commandline only one where there is no GUI. Is this doable? how do I do it?
Sometimes the website will show an alert box akin to "Are you sure you want to leave?" when you try to leave the site. Is it possible to disable this from happening, without using something like the NoScript extension?
