Basically I have a folder of .rar files that I want to unrar. I have been using the following script:for name in *.rar; do unrar x $name; done.The script works excellently, except for one thing: all of the files have the same password, and I have to manually type the password every single time. So what I try is for name in *.rar; do unrar x $name -p<thepassword>; done.
View 5 RepliesI 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
I would like to know how do I print the line # in a script. My requirement is, I have a script which is about ~5000 lines long. If there are any errors happen I just exit. And I would like to add the line # of the script where the error happened.
View 3 Replies View RelatedI create a bash script that writes another bash file. But in the generated bash file I want to write a bash command in the file and not executing it.Here's my bash file:
Code:
#!/bin/bash
cat > ~/generateGridmix2data.sh << END
[code]...
below are the details of my system. I have bash as my current shell, some really common commands aren't working.
Do I need to do a re-installation of bash? Or how do I install a selection of bash commands which I need? (for example a subset of [URL])
Code:
root@sdptfw:~ # uname -a
Linux sdptfw.sdpt.co.za 2.4.36 #1 Tue Jul 22 13:13:24 GMT 2008 i686 i686 i386 GNU/Linux
root@sdptfw:~ # echo $SHELL$
/bin/bash$
[Code]....
simple bash code:
Code:
#!/bin/bash
trap "echo 'you got me'" SIGINT SIGTERM # to trap ctrl+c
echo "Press ctrl+c during 5 sec loop"
for ((i=0;i<5;i++)); do
[Code]...
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!

Now in my bash script, I want to get the output /home/user instead of $HOME once read. So far, I have managed to get the $HOME variable but I can't get it to echo the variable. All I get is the output $HOME.
Here is my parse_cmd script:

I 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?
I have searched and searched and maybe I don't know how to articulate this issue with out just posting the problem I'm having. Every time I bring up a terminal window I get the following "Header"

declare -x DBUS_SESSION_BUS_ADDRESS="unix:abstract=/tmp/dbus-xSFd6zqrYQ,guid=dc5e07974559da016842742900000090"

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..
I 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.
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.
View 6 Replies View RelatedWhat 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.
View 3 Replies View RelatedI am trying to write a bash script that sources another bash script. Essentially, I need a few lines to check to see if a certain variable is set. If not, I set it manually, and then source a scripts with that variable in the path. I wrote a test script to try it, but for some reason the last line does not work. Here is what I wrote:
#!/bin/sh
source ~setupdir/setup.shrc #just a test, this line works
echo ${#SETUP} # prints 0 if setup is not set, which it isn't
if [ ${#SETUP} -eq 0 ]
then
SETUP="~setupdir"
fi
echo $SETUP # prints ~setupdir

On one of my servers I see this when I log in. What does this mean and how can I get it to go away? Everything seems to work fine, but none of my other machines give this error.

I'm making a script I want to be able to just call (ie, rclick instead of ./rclick) where do I put it?
~/bin?
/bin?
/usr/bin?
Also, how do I pass a variable to the script (rclick 10 will rightclick 10 times) (Found, so simple... $1)Lastly, can I force it to run on CPU2? CPU1 is completley locked up if I run this on it... Or can I make it use less cpu cycles?
I 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.
#/bin/bash
#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.
My ubuntu system hangs uppon start, think it has to do while my computer ran out of battery when installing updates. Is there way to do a safe boot so I can try to run:

I am having a problem identifying a BASH script process that I run at startup.When I use "ps -e", I see a few BASH and SH processes running, but I don't know if any of these are my script. Is there a way to give a BASH script a specific name when run that I could see as the process name. That would make it easier to identify and kill when needed.

View 2 Replies View RelatedI'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.)
terminal i open i have no history; the history is kept only in that terminal and is gone when i exit the terminal.If I count lines:as a user:
Code:
$ wc -l .bash_history
wc: .bash_history: Permission denied

If I set an alias in the terminal it stays.
Code:
alias echo="echo whoaoaaoaoaoaoaoa"
But...if I write a bash script with the identical command and execute it...
Code:
./setalias
echo
I get nothing... How do I fix this?
we are using a tool to simulate a basic computer, called TOY now this TOY has its own compiler and linker, which i will need to use in order to use *.asm files in this simulator how do i add the commands "toyasm" and "toylink" to be used in my linux bash? i have the files "toyasm" and "toylink" provided by the lecture's materials, and already managed to copy them into /usr/bin, where i found the "gcc" compile command already (been using that one before) but now i get "permission denied" when i try to use the new ones. what to do when i want to add custom compilers to my system?

I have created some bash programs (scripts). Can they be copyrighted, if yes then is it mandatory to use GPL as bash (the interpreter) is GPL'd or they can be under any license, even close source?
View 9 Replies View Relatedeverytime i open a terminal window, all i see is:

and i have to type bash everytime to get it running. i found a bandaid fix by having it type bash at the "custom command" profile preference... but i still consider the problem to be unsolved, because i still have to manually type 'bash' whenever i log remotely (putty). it seems like something happened, and now bash is not loaded by the terminal by default like it should.
PS: i already tried 'cp /etc/skel/.bashrc ~./bashrc', and it didn't seem to do anything.
I am using Ubuntu 9.10, fairly fresh install. Had one hard reset since I installed it, which could be when the problem started. Also, I was messing a bit with profiles, switching their ID's and adding/deleting them (not sure if that would be the problem).
Just installed 10.04 64bit and in gnome-terminal i have no bash completion when sudo is used.For example:apt- gives apt-getbut sudo apt- does nothing, i get no suggestions from the terminal.
