I want to use nohup and script command together but they don't work. Normally I use
Code:
script -c "./run arg1" run-log.txt
Then I want to send that command in background with nohup:
Code:
nohup "script -c "./run arg1" run-log.txt" &
but I get this error:
Code:
nohup: ignoring input and appending output to `nohup.out'
nohup: cannot run command `script -c "./run arg1" run-log.txt': No such file or directory
I have a ssh command as shown:
Code:
ssh remoteusr@<ip> "perl ./monitor.pl count_pages" | /monty/graphs/mail.pl
This command connects to remote machine and fetches data which gets continously streamed at screen(shown at terminal). If I do Ctrl+Z and bg to put it into background. Works Fine. But when i close the putty, it gets closed surprisingly.
I tried with nohup <command> & But wonder how to provide password.
I had a make file which deals with hundreds of thousand jpeg images. I submitted this job by using: nohup make & Is there any possible way that brings this program back to foreground? I can only use ps to monitor the status, command jobs cannot find it.

nohup bash -c "while [ true ]; do echo test; done"
from PuTTy SSH client but after this process is not runned in background instead nohup keeps to be foreground process in shell.
SW version: nohup (GNU coreutils) 8.5
If I start a process with nohup:
nohup WHATEVER &
then how can I see it again? I mean how to attach my terminal to it again under Linux, e.g.: Ubuntu 11.04 - just like with the screen package.
Does the nohup command make a process immune to the HUP signal by sending the process to the background or does it achieve this by some other means? If it it does send it to the background, then are all background processes immune to the HUP signal? If yes, then we can make processes go to the background for getting immunity against HUP by using the bg command as well can't we?
View 2 Replies View RelatedI ran a perl script in background with nohup and disown to make sure my script runs even after the parent process is terminated.
Method 1: nohup
> nohup perl run.pl &
[1] 2080
Method 2: disown
> perl run.pl &
[2] 2448
> disown
In either method, the script process doesn't seem to connect to init process, when I checked using pstree command. I thought, the disown or nohup command detaches the process from its parent and attaches it to grand grand parent init process. And it disables SIGHUP signal to my script process. But the pstree command didn't show me what I expected. It still shows my script process attached to my current terminal process. I just don't understand the concept behind these two commands (nohup and disown). Is there any way, I can see the list of processes that are run by nohup or disown command?
When I run a script with nohup, the output is forced to the out.log file by default; is there a way to force the output to the screen instead of the file? I need to be able to see when my script gives me a "process started" message, and I don't want to clog up the system with log files.

I'm the noobiest noob you'll find on here. I'm having trouble getting ruby on rails to work with mysql on redhat. So on their forum I asked how to install the latest "sqlite" database package on linux.They told me to run.Now, I don't think I need "sudo" because I am the root user on my database, and I don't think I can use "apt-get" because I'm using redhat, not ubuntu.
1) Is there a way of running the above command on redhat? (A redhat command for installing things?)
2) How can I be sure I'm using redhat and not some other OS?

View 5 Replies View RelatedI have a big bash script ,its goal is to download movie one by one . But I often get into a problem: if this script is executed in cron,it often does not completely download the movie.I often find the movies it downloaded are several KB while the movie is actually 20MB.So I think it is because it did not wait for finishing one task ,and jump to download another.So I want to know ,is there a way to force the bash script to wait until one movie downloaded completely and then start to download another movie ?

$cmd If this script is executed, an error is generated. The reason written was that "The execution fails because the pipe is not expanded and is passed to date as an argument".What is meant by expansion of pipe. When we execute date | wc on the command line, it goes fine.then | is not treated as an argument. Why?
I am using openSUSE 10.3.When I install software from tarball then to record time required I send output of date to beg.txt(when installation begins) and end.txt (when installation finishes).How can I append output of date to a file so I don't need two files?

I tried

which does not work on the invisible directories (why?). When I used ".*" as wildcard it changed all (visible) files including the parent directory (the one I was currently working in which is the "dot") . I can change the invisible directories owner and group using dophin but how is it done from the command line?
I want to be able to use Ctrl+R to have reverse-i search. Also if I press Shift+Up Arrow after typing the first few characters of a recently executed command then the shell should complete the command by finding the most recent commmand having the same first few characters.
View 1 Replies View RelatedBash's command history is great, especially it is useful when adding the history -a command to the COMMAND_PROMPT.However, I'm wondering if there is a way to log the commands to a file as soon as the Return key is pressed, e.g. before starting the command and not on completion of the command (using the COMMAND_PROMPT option would save the command once the prompt is there again).
I read about auditing programs like snoopy and session recorder like script but I thought they're already too complex for the simple question I have. I guess that deactivating that script logs all the output of the command would lead already in the right direction but isn't there a quicker way to solve that probelm?
When you run the following cp command in the BASH terminal, how does Linux know which files are the source and which are the destination when copying multiple files from one location to another?How does Linux know that the services, motd, fstab, and hosts files are the source and the /home/fred/my_dir is the destination?This question came up in a Linux class and I was not sure of the answer. I was thinking it is based on the source path entered ending with a file path and the destination being a directory, but was not sure.
