I've noticed something, and hoped there was a work around.when I write a simple bash script, and run it, if I close the terminal i ran the bash script inside, the bash script stops. What are the solutions for this? Basically I want to run my bash script and close the terminal, keep the bash script running.

I got a problem with terminal, since i'm really a noob with terminal i don't know how to fix it.Everytime i type in a command it shows for example:
-bash: ls: command not found
Even the basic commands don't work... just cd <directory> and those things works
What happens when the script executes is that the ssh connection works and parks me at the remote hosts's shell login. Therefore, the "firefox" command refuses to execute. I need to know how to make the "ssh" connection occur, stay open, and go into the background so that the rest of the script can execute.If I could also do this with the "firefox" line so that the entire term window could be closed would also be helpful.

To be honest I cheated and used the .bashrc / .profile files from Ubuntu and all was working fine for a while now and it seems something changed to cause this... any ideas on why I am getting this? I checked my .bashrc and my /etc/profile and it doesn't look like anything is amiss..

Writing script to create backup of file by adding datetime to file name. Basically test for file presence if there, cp with datetime then rm original cp works fine from command line but get cannot stat `full path to file': No such file or directory
Code:
Here are the errors: cp: cannot stat `~/html/CVP_dadamail/.dada_files/.logs/errors.txt': No such file or directory rm: cannot remove `...': No such file or directory
The for statement is a placeholder as I have same file to backup out of several directories. using "bash -x scriptname" -OR- inserting echos, I can see I've constructed the strings properly. Believing it might be related to the hidden directories, I tried setting the shopt "glob" options to no avail.
Ultimately I'll add the other directories to the for loop and then run this from a cron job, so if you see potential pitfalls knowing I'm headed in that direction...believe construct would be

Totally new to programming (as of this morning) so please bear with me I have a bash script that stops working after the first while loop.
#part 1

#part 2

Every arguement above the first loop completes (including the first loop itself) but anything below (incuding the second while loop) doesn't finish. I know that it isn't a problem with an unending loop... it seems to be something about the While loop that I'm not understanding... but I can't figure it out. I just need arguments below the first while loop to take place.
I mainly use debian jessie , recently i have installed daragora as my second os to get a feel of gnu/linux . the problem is that dragora uses bash , and it's commands are different from debian jessie terminal is there a way that i can use the same commands here in dragora?
View 4 Replies View RelatedLinux-goers. I did some research on this, but I am still fairly new to Linux. In Ubuntu 10.10 (Maverick), I accidentally overwrote my "/bin/bash" file. Dude, using "sudo" with a small typo can work disasters. Bash is now broken in the Terminal (gnome-terminal). Terminal itself still works fine, technically, but bash is still hosed/broken. Here is what I did to try to fix it: Booted from Ubuntu 10.10 live CD. Mounted my Ubuntu partition and manually copied the good/fresh "bash" file onto my hard drive. Verified copy was successful. Didn't help, as you see. Reinstalled "gnome-terminal" using synaptic package manager. Tried to reinstall bash via synaptic, it failed with error, "E: /var/cache/apt/archives/bash_4.1-2ubuntu4_i386.deb: subprocess new pre-removal script returned error exit status 2"
In Terminal, all basic commands work as far as I can tell. ("ls", "pwd", navigation, etc.) Here are some problems:My "username@computername" does not display in the prompt; only the $ sign. Bash keyboard shortcuts such as uparrow and tab do not work. Instead, each inserts a key code. I can't even move the cursor left/right. Aliases (a function of bash and .bashrc) are broken, of course. My sanity level decreases when I use Terminal now. For what it's worth, even with "sudo" I get a "permission denied" error when trying to run Google Chrome! I read something about a ".bashrc" file being a possible problem, but I don't know how to make it work, or the file's proper locations in Ubuntu 10.10. Is there something I can do with a "make" or "apt-get install" command or something?? Could this simply be a permissions problem? Is the link to "/bin/bash", "/bin/sh", or a ".bashrc" file broken? Guide me, oh Linux gurus.
P.S. I always wondered what exactly bash was and how it was different from the basic terminal. LoL, this is an excellent way to demonstrate the difference, and I WANT IT BACK!

I am attempting to write a backup script that will do the following:
1) lock and flush tables on a mysql db
2) dump the db to a file
3) unlock the tables
4) rsync the file to offsite storage
It all seems to be going well. However, obviously I don't want to setup ssh to the storage server on another network as the root user without a password. so I am attempting to su as the backup user inside of the script but when I try to run the script everything happens as it should until I try to so.. then it jumps out of the script .. akss me to login as the backup user.. proceeds to rsync to the offsite storage it does all this and then resumes execiting the script. it is not going to be setup as a cron job. it will be executed manually. assuming that is the case, how can I get the script to run without prompting for a password?
Here is what I've come up with so far... assuming that the script is run as root and the identity of the backup user will need to be assumed inside the script without perstering the user to enter the backup user's password.

I wanted to change my $PATH and my prompt, had some trouble with setting and exporting the variables and found that the shell was csh instead of the bash which I expected. I worked around it by creating a .cshrc which calls bash but don't know what caused the change. I've got as far as seeing that the gnome-terminal command kicks it all off from the Applications>System Tools menu but what happens between there and the terminal popping up?

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!
