Sep 22, 2010How one could determine (for use in a Bash or Python script) which device (eg /dev/sda1, /dev/hda1... etc) a ramfs was loaded from when booting from a USB drive.
I have a RIPLinux/Tinycore live USB disk that automatically needs to run a script that is stored on the same USB drive but not part of the RIPLinux/Tinycore image. (Please note that I do not want to put this script into the RIPLinux image.) I therefore would like to remix the RIPLinux/Tinycore ISO to automatically run this script once it has started up. After RIP linux has booted I would like to automatically mount the USB drive that RIPLinux/Tinycore was booted from. I need help detecting which device this is.

Programming :: Bash Ctrl+c Tarp And Bash Read With Timeout?
Jan 24, 2010simple bash code:

trap "echo 'you got me'" SIGINT SIGTERM # to trap ctrl+c
echo "Press ctrl+c during 5 sec loop"

How come code behaves normally and stops when ctrl+c signal is caught and resumes, but after I use at least one timeout read in the code it looks like, if signal is caught again it doesn't pause the execution but skips the loop. If you remove -t (timeout) option from the read, both loops look the same!

Programming :: Run Multiple Bash And Php Scripts From A Bash Script?
Jul 25, 2011I have written quite a few separate bash & scripts and php scripts that up to now I have run from cron jobs. However I have to estimate how long each takes to run, before running the next and so it probably takes much longer than necessary to run them all. They have to run in order.
Now there are so many I am thinking it would be better to have a master bash script that would run one after the other, but I am not sure how to get the master script to wait before starting to run the next script. Is this possible and is there a command that will make the script wait between bash and php scripts , for them to finish, before running the next?

Programming :: Bash: Get Filename And Extension Using Bash?
Jan 9, 2010I would like to get the filename (without extension) and the extension separately. The best solution I found so far is:
Let FILE="thefilenameofsomefilesfor_instance.txt"
Code:
NAME=`echo "$FILE" | cut -d'.' -f1`
EXTENSION=`echo "$FILE" | cut -d'.' -f2`
I think it would be better to count the len and remove 3 chars to right to get the extension, but it can be macintosh filenames with have 4 chars for extensions.

Creating a new partition (100gb) and copying my Ubuntu partition (10gb) to the new partition. After it was copied, and pasted, the original partition was deleted.

Ubuntu :: Using Bash To Shutdown?
May 1, 2010I would like to make a bash script that shuts down. Problem is... How am I supposed to do this when shutdown requires sudo and ultimately requiring me enter my password as a response?
I.e.

#Do: shutdown at xx : xx time
shutdown 23:45
#done (yea just one line...)
How could I make sure my password is given to the sudo response without manually entering it ever time?
How could one make this script run automatically i.e. on startup every time.

View 2 Replies View RelatedDebian :: Bash From Ubuntu To 6?
May 8, 2011I'm in the process of switching from Ubuntu 10.04 to Debian 6.0. The install went pretty well after some tinkering, but I want to replicate my bash environment from Ubuntu to the new Debian system.
I've copied over my /etc/bash.bashrc and my /etc/profile. I renamed my ~/.bashrc, logged out and back in, and expected to have my original shell environment because I would be defaulting to the system-wide settings in /etc.
Instead, the stock Debian environment remains: No completion, only the $ prompt, no up-arrow history, etc. I don't get what it's reading from and why /etc/bash.bashrc isn't being accessed. (Bash completion is installed.)
