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.
I am running a command pretty similar to the one below:
Code:
I need to capture the exit status of that part of the command.
What I am trying to do is set a variable that can be modified within my_job.sh, and used to exit.
However, no matter what I set "status" to in my_job.sh, it exits with "0".
What can I do differently?
How exactly can I use the exit status of a command in an if statement ?
Something like this:
Code:
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

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'm trying to capture incoming/outgoing phone call data. Both telnet and nc have allowed me to easily direct this data to a file for later processing, HOWEVER I can't seem to get either to work as a background process. I want to put the connection into a shell script and run from cron.
View 4 Replies View RelatedI have a script that calls another program/script, xxx, to run in the background. Supposedly this program at most should finish within five (5) minutes so after five (5) minutes, I run some other steps to run the script into completion. My problem is sometimes the program takes longer than five (5) minutes and this is causing problems when running the rest of the steps in the scripts. Can anyone suggest how to re-program my script. At the moment, the KSH script, i.e. test.ksh, is doing as below:
test.ksh:
.....
.....
xxx/xxx.ksh <--- program/script called by the script
sleep 300
..... run the rest of the script .....
..... problem is sometimes xxx/xxx.ksh takes longer than 300 seconds .....
..... any way that I can monitor that xxx/xxx.ksh finishes before I run .....
..... the rest of the scripts .....
how to make a script that will check service/s status whether running or stop and also will run stop services?
View 9 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

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.

Can't boot into Ubuntu. Using recovery mode, I get fsck exit with status 3 error. I did man on fsck and there is no reference to status 3. Same issue as [URL]
I have my data on sdb3 which is having this issue. File system is ext4. I can't go into shell or anything, I get the fsck error and the system reboots right away and stuck in that loop.
command will just execute and exit with a status of "0" -"Every command returns an exit status (sometimes referred to as a return status ). A successful command returns a 0, while an unsuccessful one returns a non-zero value that usually may be interpreted as an error code. Well-behaved UNIX commands, programs, and utilities return a 0 exit code upon successful completion, though there are some exceptions."[URL]With the command . . .
Code:
# dosfsck -v /dev/sdb
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. [URL] is there anything like this script COMMAND_LAST used in the following link. [URL] that can be entered in the terminal window after - or at end of - my dosfsck command or any command. just to see if it has a 0, 1, or 2 status ?
