General :: Bash Shell Script To Check / If Empty Files Are Being Created & Start Process

Jun 25, 2010

I have an Ubuntu server in which a file is dumped every hour and a new file for the next hour and the process continues. If there is any problem due to which the creation of file stops then empty files are created every minute till the process is killed & started again. I need help to make a shell script to check if the empty files are being created and then kill the process and start it again.It would be a great help if anyone can help me regarding this.

May 26, 2010

I need to process billions of small files using bash shell commands with limited memory size (256MB). If any of those files contain certain "keywords", the file will be removed. I tried with command:

find . -type f -exec grep -i -l -H "keyword" '{}' + | xargs rm -rf

where all files are located within the current directory. But the command above failed in "out of memory".

Ubuntu Servers :: Server Process Created Files Permissions

Nov 20, 2010

Currently have access to a VPS where we are running a small game server on ubuntu - the problem is that it is a multi-user environment, so when one person restarts the server process, all files it creates are owned by that users name and group. I have created a group called 'game' and added both users to it, but I need to know how to make all files in the game server's directory to be r/w/x for the group 'game'. Currently, I have a script that chowns and chmods all files recursively on startup, but I'd prefer not having to do this.

General :: Bash - Rename Files With Spaces Using System Shell?

Jun 8, 2011

I named a number of files with spaces in them, and I want to replace the space with "_". However, every time I write a command in the shell with the file name (eg "Spring 2011"), the shell doesn't recognize the file or directory. What can I do about this? Is there any way to use the unicode character for a space?

Ubuntu :: Shell Script Using Bash / Get The Date Of The Process Takes Longer Running?

Mar 29, 2010

I need show the number of process per user, and after the date of the oldest process per user also.

With "ps -eo user | sort -u" i get all users that are running any process. And with "ps U username | wc -l" i get the number of process that the user "username" is running.

But how can i merge both commands for do what i need? Like a FOR or something like that. There is any method of make a FOR using the list that i get with the first command?

And then for show the date of the oldest process.. with "ps U username | sort -k 4" (4 is TIME field) i can show the process of the user "username" sorting they by time. But how can i get the date of the process takes longer running?? I can get only the time, but no the date.

Programming :: Start A Process And Send Input To It In A Shell Script?

Jun 9, 2011

I'm building a Linux From Scratch system and partially automating it. I will likely want to do it again, and I would like to try to almost completely automate it.

My current approach is a script that takes an input file and sequentially runs each line in a new instance of bash. If one fails, it gives me the number of the step that failed so that I can use the "--step" option to resume after I fixed the issue.

This has some problems:
A varible created on one line will not be accessible on the next line. This is because each line is run in a separate shell (the reason for this is so that the commands in the input file and the script's internal variables can't interfere). You can't switch users or use chroot, again because each line is run in a separate shell.

What would be nice is to be able to start a bash process in the background and send commands to its stdin. I guess that a named pipe would work, but the named pipe will be gone after a chroot. Is there a way to do it without relying on the filesystem? Also, how do I know if the command failed?

General :: Can I Do Integrity Check When Tar.gz File Is Created?

Mar 25, 2011

create one tar.gz file that contains my /home, /etc, /root directory.

a) The process ended with a 88GB file size (which is ok) but with the following message.Code: tar: Exiting with failure status due to previous errors.I have searched a little but I could not find what went wrong.

b) What are the limitations of tar and gz for backups. Of course I fully understand that they can not be used for differential backups (if it is called like that)

c) Let's say that my backup will be a file of 100GB and I want to see the contents of the .tar.gz. In kde there is a program called ark. Can ark handle so big files? Does it use my hard disk (eg. /tmp) to uncompress the file so to show me its contents? It might be the case that might be the compressed file is much bigger than the left space on the hard disk?

d) How can I do an integrity check when my tar.gz file is created?

General :: Empty Bash Command Line?

Sep 28, 2010

I am looking for a way to delete the currently entered commandline without wasting seconds on the "Backspace"-key.

For example I scrolled the bash history and have a long commandline that would execute when I pressed ENTER:

~$ aptitude search openssl | grep dev

But now I decide that I do not want to execute this command. Can I get an empty prompt fast without deleting the whole line with Backspace? On the Windows "cmd" you can just press ESCAPE and it is gone. This behavior would be what I want.

The question may seem trivial but this is bothering me for a long time now.
