I'm trying to create a backup script. For my second version, I want to make a GUI that will ask the user three things:
1. which folders should be excluded
2. where to store the backup
3. the user's email
I need to store this input, and later input the values into variables in my script. How do I go about doings this?
In what files/dirs in the home dir does xfce store the user config data?
Or if you like.
What files do I need to restore from backup in order to restore my xfce desktop with all the different settings I made?
Edit: All user config files is usually stored somewhere in /home/$USER/. And since all the programs, kde, xfce and gnome stores their config there, this question is about what files belong to the xfce desktop.
This is my guess of what files belong to the xfce desktop:
.config/Thunar/
.config/xfce4/
.config/xfce4-session/
.config/user-dirs.dirs
[Code]....
in bash scripting...say I want to take the input from a user via a question...I would do this:
Quote:
#!/bin/bash
echo "How large do you want this partition to be in GB (enter only the number)?" read PART_SIZE echo "You want your partition to be $PART_SIZE GB" But I don't want to echo it back to the screen, I want to add it to the content of /etc/fstab. I have been mucking around with sed to find the tmpfs partition in /etc/fstab and add the partition size attribute (this is to use the onboard RAM as a volatile partition)...but am not having any luck...
The portion of /etc/fstab that uses /dev/shm for the tmpfs partition is:
tmpfs /dev/shm tmpfs defaults 0 0
So, if a user says "24" GB to the answer (from above), how do I get it to automatically add that value to the tmpfs partition line in /etc/fstab? So it would look like:
tmpfs /dev/shm tmpfs size=24g,defaults 0 0
I understand that I would also have to come up with a way to put "size=XXg", which I could do with a copied over generic file before this action...then the script would have to find "XX" and replace it with the user's figure...
I have a BASH script which at one point asks the user a yes/no question. I want to make it so that if the user types in an invalid input 3 times consecutively then the BASH script will echo an error and terminate with exit status 1.
View 9 Replies View RelatedI've written a bash script that allows a user to input a directory location to find out the size of the directory. However, if the user inputs a directory and finds its size then inputs another directory then wants to quit, the script asks the user numerous times if he wants to quit!! The script won't exit until the number of times the user looks at a directory is reached! What gives?
Here's the script:

I've been using python/bash to help myself automate things for a long time, however I am curious. One reason I use python more is because I don't quite know how to work with user input in Bash, such as getting it to ask for input and wait, and then placing that user input into a command.

I have a script im having some problems with, what I need is to have the system generate a random password for me and use that password when creating new users to it.
System is Debian Lenny and script is in bash.
The program is znc. I have made it so that it will generate the random password on the shell but the problem is to use it in the bnc software.
To make a password there the command is znc --makepass and look like this:
My question is now if it would be possible to put in the script so it would "answer" when it need those passwords ? the random password that is generated is in a variable called $setpass and is NOT crypted.
Or is there any other software that would be able to generate that md5 string for me ?
I have a program that I run from the terminal that requires manual input (it's matlab in mex debugging mode, matlab -Dgdb, which starts the GNU C debugger with its own custom settings).
Every time I run this program I always type in the same few commands in the program's interactive shell before I actually start working (for example: run -nojvm; stop at mexFunction; continue). I want to avoid typing these commands and I thought I could do this with shell scripting, saving the commands in the mycommands file, then running: myprogram < mycommands
The problem is that this runs all the commands and then exits the program. I want it to run the commands and return control to me so I can run my commands. Is there a way to tell the shell to use a file or a string as the input to a program then immediately return control to the user without the exiting the program?
How do you catch user input while the script is running? Or, how would you make two scripts run at the same time, but use input from one script to the other? The program I'm trying to make, echos text on the screen continuously, but while thats happening, I want the user to be able to input something, so the program can detect the input and display something else. So I thought maybe I could make two scripts run to do each task.

Code: Select a file:
[1] foo.tar
[2] bar.tar
Enter a selection: I have already coded each possible selection to have its own variable. If the user selects 2 I need to select $SELECTED_TAR2, or if they select 1 I need to select $SELECTED_TAR1 and then do something like this behind the scenes:
Code: cp /home/user/$SELECTED_TAR2 /home/user/backup/$SELECTED_TAR2

Here's a challenge I've been struggling for months with:
I have a bash script that reads URL addresses of our internal server and then executes some test commands on them. Something like this:
Code:
read -p "Enter URL: " url
sh execute-what-ever-to $url
After copy-pasting the URL the user taps the enter key and the script proceeds, but here comes the tricky part: I want this to work without the need to press the enter key after copy-pasting the URL.
"read -n" does not work in this case, as the URLs vary greatly in length. However, the URLs always end to the same string. They could be like "http://url1/END", "http://url2/END" and so on. So this ending string "END" could be theoretically used to recognize that the whole URL has been pasted.
I have a system setup script for my Slackware installations that pulls all packages and source files from another machine and sets everything up to be identical between machines.

View 3 Replies View RelatedI'm creating a bash script to do some tasks for me. I would like the script to be run at a set time of everyday. My first question is if it is possible that if one of the commands in the script requires sudo, is there a way to get around it with out making sudo not require a password. Such as, is there a way to include the password in the script? If that is the case, I can always just set the file as read only by sudo. I've been looking for a way to do this, with no success. if I have a command that wants input, how do I give it to the program. For example, if I want to make a zip file that is encrypted, the command would go as:
Code:
zip -r example * -e
now how would I get the script to insert my wanted password.

I have a script which checks on my jobs that run on some cluster.The script, "script.sh", takes as an input the job-id for the job to be checked. Sometimes I have 100s of jobs and I want to check them all (for successful completion.) I could put these job-ids into a text file, "job-id.txt", each id in its own line.For each job-id, the script would ask me few questions (with a yes or no answers) to see if I want to do some other checks for each job-id.I want to know how may I direct my job-ids from this text file into the script one job-id at a time.

I'm writing a bash shell script that among various other things will traverse through a directory with hundreds of files and rename those who match a pattern found in a config file. It's expected that only about one in ten files will actually match, and those who don't, will simply just be ignored for this purpose.
This should for instance cause the file "dBase program file December 1987.prg" to be renamed "Clipper source code December 1987.prg", and conversely "C++ source August 1996.cpp" to be renamed "C source code August 1996.cpp" etc.A sample file such as "Random Data File.dat" should not be renamed here since it's not mentioned in the config file..What is the quickest, most elegant way to do this in bash?I am thinking of using bash's built-in regex matching combined with the /bin/rename utility, but don't quite know how to get started to catch this..I guess there are plenty ways of doing this in perl and elsewhere as well, but since this has to integrate into a pre-existing bash script, that's what I'm looking for.Anyone out there with a spare moment to offer a hint in the right direction?
Write a program that requires the user to input the name of a file as an argument. If the user fails to include one argument it should make use of a thread that handles a signal. The signal handler should tells the user Incorrect number of arguments and then calls the terminate signal on the process.
If the numbers of arguments are correct then the program should allocate memory space to the file (5MB) and create a child process that requests the user for a character that it should send to the parent. The child should keep request for data until the user keys in the character O. During each request it should pause for 10 seconds, send the character to the parent and then requesting again for another character.
The parent should get the character from the child. Do not make the parent wait for the child to finish requesting for data. Make use of pipes to facilitate communication between the parent and the child. A second child should be created to read and display data from the file. Make use of any appropriate Inter Process Communication technique to ensure that the second child and the parent do not access the file simultaneously (Mutual exclusion).
I am trying to write a bash script that installs a program fully automated for me. I am stuck at the one part where i need to change a line in one config file. I have tried various syntax for sed and none have worked. Maybe someone can suggest how to go about this. Since the line appears in the middle of the file, I can't use echo or cat. Also the file will be diffrent lengths depending on the install.
The line I need changed is:

the last syntax i tried is:
Yes this is for PNP4Nagios on centos 5.6 64bit. If i can get this figured out. I will be willing to post the whole thing for others to use. it will be used to install PNP after a working nagios install is done.

i just installed ubuntu yesterday (dual boot) and ive finally decided i wanted to wipe windows xp off my hard drive first of all i know how to delete partitions and such but then i went to g parted and saw all this crazy info (screenshot posted) im really confused and down wanna end up ruining my installation.
But what i want to do is remove my xp installation merge the empty partition with my linux partition and then rebuild the grub2 config file.
Now, I have one script called "defcon" defcon gets the current DEFCON level and outputs it using echo.
Code:
#!/bin/bash
DEFCON=`curl -s http://members.tripod.com/~Swat_25/defcon.html | sed -n '/^$/!{s/<[^>]*>//g;p;}' | sed '/^$/d' | grep '[12345]$'`
echo "The current DEFCON level is $DEFCON"
The second script ("tweet") updates my twitter account.
Code:
#!/bin/bash
curl -s -u USER:PASS -d status="$@" http://twitter.com/statuses/update.xml > /dev/null
What I want to do is be able to update my twitter account with the current defcon status (this is really more of a learning thing than something I actually want to be doing). The original script for tweet replaced $@ with $1, but if I use:
tweet `defcon`
it only uses the first word in the string, similarly if I used $2 or $3.So I changed it to $@. The normal function still works, but typing:
tweet `defcon`
updates twitter with nothing.
EDIT I should mention the /dev/null is there to catch the output of curl, otherwise it won't run silently. It still updates twitter normally with the send to /dev/null

View 5 Replies View RelatedI have two students whose windows laptops are riddled with malware and not working properly. They want me to help them install Linux (which we use in school), but they are concerned about their iTunes.
Having avoided iPods as "defective by design", I know nothing about iTunes whatsoever. However I remember reading about DRM locking and such problems that have me concerned that I won't be able to do it.
Where does iTunes store its stuff?
Can I copy its data store to an external drive, and then into a linux home?
Then will it work on wine, or can another manager (rhythmbox etc) access the itunes data?
Alternatively, if I partition the drive and install linux, can rythmbox/wine/something access itunes data on the win partition?
Supposing they are buying music through iTunes, what will happen to that account?
Finally, one of them has an iphone. Does that work with linux?
Ironic that an apple application is blocking migration away from windows.
