View 5 Replies View RelatedI'm writing a script that performs backups from partitions on remote servers. I used to do this with ssh, but that seems to be somewhat slow, so I switched to netcat.I start a listener on the receiving server (which runs the script) like this:netcat -l -p 7000 | dd of=imagefile &and then I make the remote and start a dd piped to netcat. This works quite well started manually and the listener is waiting in the background. However, when I have cron run the same script to automate it, the netcat listener is not started, probably because the "&" thing does not work (or there is something with the piping that behaves differently then)
View 7 Replies View RelatedBecause of my English skills I'll try to explain this subject as best I can, thank you for understanding. Fisrt of all, I am running some program on my slackware in background (using standard method - &). I need to make a script, which allows sending command to this process on my machine from another one. Furthermore this program have to be logged out (standard output f.e. ./myprogram > log.out.txt).It might be a separate Program A which runs my Program B but it cannot be screen, because it is not working like I'd like to and it cannot be java, because it's slow and working not the best so to speak
View 6 Replies View RelatedThe first call to "somefunction" works as expected. The function prints "endfunction" and a process in background sleeps 30 seconds. In the second call I thought it should work in the same way, but the script sleeps 30 seconds before it prints "endfunction".Does someone know the reason of this behavior? Is there another way to do a command substitution of a function that has a background process without have to waiting for that process?

View 1 Replies View RelatedHave a bit of a dilemma I'm trying to track down. Have a user using both date and ps commands with & at the end of the line in a shell script. When he runs the script, it waits until he hits ENTER to get back to a prompt. Other times he doesn't. Also, I've noticed that this will sometimes happen, then immediately rerun the script and the behavior stops.

View 2 Replies View RelatedI originally have Ubuntu Lucid on my machine. I just installed opensuse 11.2 on another partition without bootloader installed. So I'm still using the Ubuntu Lucid default bootloader grub2. I can boot up opensuse correctly. the nagging thing is that there's no splash screen show up during the boot process, instead, lines of command are flashing, the console background is also missing and the font under console (tty1-6) is huge. what can I do to have these back to opensuse? the current entry in grub2 for opensuse
Code:
menuentry "openSUSE 11.2 (i586) (on /dev/sda2)" {
insmod ext2
set root='(hd0,2)'
search --no-floppy --fs-uuid --set 9ac05ede-e7c4-47f3-b55b-66d5844$
linux /boot/vmlinuz-2.6.31.12-0.2-desktop root=/dev/sda2
initrd /boot/initrd-2.6.31.12-0.2-desktop
}
which parameters should I add?
I have spent the most part of 5 hours trying to fix this issue. For some reason I cannot change the background image to any of mt .jpg wallpaper files (and .png files). I've tried using the Ubuntu-Tweak application, but I end up getting a purple screen (default) or a black screen (default). So then I tried using the terminal method by making the Appearance window appear when I would log out. That works, except when I go to use my background image, it shows as a question mark for the image preview, and the icon for the file is a gray box. All while doing this my background images that I tested are all in the /usr/share/backgrounds location. Please help! I really want to get rid of the default images and use my images... :/ My desktop/screen in 1440x900, and most my background images are around that size. They work with my regular desktop for my account.

I'm currently using Ubuntu 10.10. I frequently end up opening a few terminals and it's easier to keep track of what I'm doing if the terminals have different backgrounds or are colored differently. Is there a way already made which will start up a new terminal with a background different then one that's already open? Or a way that when the terminal is opened it will start the terminal under a profile that's not yet open? That being, when I open a terminal it opens the "first" profile. Then once I try opening a new terminal it checks and finds that I already have one with the "first" profile open and so the new terminal is opened with the "second" profile.Does anything like this feature already exist? Or something like it?

> php -f filename.php
It works great. But of course, it stops when I close the SSH window. I need to be able to run it and leave it running. The script is a crawler and it takes about 3 hours to complete it. So I tried this:
> php -f filename.php &
This doesn't work at all. It doesn't even execute the script.

I know of terminating a command with & and then moving it into the background by pressing Ctrl-Z and then bg [pid], and I also know of nohup. But say you started a process that turned out to take much longer than one expected, is there a way of pulling, so to speak, this process from another terminal screen into the background so that even if I log off from the server the process would continue?

While coding Python, I tend to save files very often (I have a pretty high code->test->code->test->... frequency). I hate when Linux syncs my changes to disk everytime I do a write.
How do I configure Linux so that it keeps file writes in memory for a certain period of time/number of writes?
To make this any useful, of course reads to not-yet-fsynced files must be from memory (so that the Python interpreter always sees the latest contents). Extra credits for background-fsyncing that doesn't block other writes/reads going on at the same time :-)
