I am attempting to learn how write bash scripts. I want one to ask for a specific key. For example, I want it to ask a question, then if it is like, y for yes, or n for no, it does a specific thing. I'm thinking it would be something like:
Code:
#!/bin/bash
echo "Are you a boy? y/n"
read -t3
I'm trying to write a script that involves storing a specific PID in a variable. I've got as far as: -

I want to make specific keymaps for application, that working only in it and doesn't affect other apps.
For example, I already use my Caps key to toggle input language (via xorg.conf), but I want Capslock to behave like Esc in vim.
Looks like xmodmap doesn't have any options related to that.
I have switched to openbox from Gnome and would now like to stop using Metacity altogether. When I was using metacity I had both a control theme (e.g. gtk theme) and fonts set up how I liked them in gnome-appearance-proporties. When Openbox starts, it gets my window borders up properly (ofc.) but fails to render my fonts properly and uses the wrong gtk theme. I can't find anywhere to specify which gtk theme to use or what method to render my text with. After Openbox is finished doing it's thing, and I run gnome-apperance-properties manually, it will automatically set everything to it's proper value, but I don't want to have to do this as it takes several seconds to preform and I'd rather not have it jury rigged like this.

View 3 Replies View RelatedI am administrating a lab in a university and every semester we need to delete all the home folders of the accounts for the next semester. I would like to make a bash script that does this automatically and having trouble with it. Note that I am writing my very first bash script. What I need to do is make a script to delete the following:
Delete everything in /home/$exp$num/$dir
when "exp" could be either "rt", "ic" or "sp".
"num" could run from 1(single digit) to 45 and dir is "profile" and "work".
This is what I tried to write:
Code:
#!/bin/sh
cd /home
for exp in "rt ic sp"

What seems to be the problem is the reading of "$exp$num" as a joint expression.
I use rhythmbox to do download my podcasts and I'd really like to automatically sync the new files to my phone when I attach it.The phone mounts as an external drive so I was kind of hoping to write a script that would run automatically when the drive mounts.

I'm new to bash scripting and I've searched around the forums and Internet for this but haven't had any luck. I've found similar things but not what I need. What I need to do is write a simple script that uses what the user inputs to locate and display where a file is. I would prefer to use locate instead of find since I know that the person I am writing this for has locate on her machine (my mom, who is just beginning with Linux).I'm writing the script to make things easier for her while she learns In this particular part of the script I would like to be able to have the script prompt to enter the file she is searching for, read the her input and then display for her where the file is. I realize it would in most cases be much simpler just to teach her how to use locate, but she is very impatient and this is just a part of the script I will be writing, but I can't figure out how to do this.

What i want to do is pretty simple.I want to uncomment every line that begins with "deb" (except for deb cdrom) in /etc/apt/sources.list.I know how to do this through system > administration > software sources.I know I can gksu gedit /etc/apt/sources.list.I'd rather not do it that way.I'd rather have a script do it. It's less work, less typing, less clicking, and would work the same on every ubuntu version.
View 8 Replies View RelatedI'm trying to call a specific variable based on a user selection. For example:
Code: Select a file:
[1] foo.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

I look after a server which accepts automatic overnight PASV FTP uploads from remote clients. When the uploads are complete, my Bash script copies the files to another location. The problem is, my script needs to be a bit smarter when it comes to detecting active FTP sessions.
I was using:
Code:
netstat -n | grep ":21 " | grep ESTABLISHED
to test if there were active sessions, but came unstuck when a local user left an unrelated FTP session active. The result - my script hung around all night thinking there was an active upload from a remote client. My server is behind a firewall, so remote clients all show an internal (NAT) address,so I can't differentiate by source IP address.I can't install LSOF or FUSER for security reasons. Is there a way I can test for active FTP sessions from specific users? I am running Red Hat Enterprise Linux Server release 5.2 (Tikanga).
I'm trying to write a bash script which will find files then move them to a specific directory.
So far I have:
Code:

src_dir="/path/to/source/directory"
des_dir_mov="/path/to/destination/directory/for/movies"
des_dir_img="/path/to/destination/directory/for/images"
find $src_dir -iname '*.avi' -type f -exec mv '{}' $des_dir_mov ';'
I'd like to have all the possible movie file types then the image file types checked in a loop.
Every time I try to include an array in this script it breaks

View 9 Replies View RelatedThis question can be found on the Internet and on this forum but either there is no response or the advice is to move the folder to exclude on another path (in case of using a subfolder for ripped/downloaded mp3).
But in my case my music is on a SAN and I access it through CIFS. So every time I delete a file or folder it goes to the Trash, in a folder called #recycle, which Rhythmbox indexes as well. So I have to delete this folder to avoid duplicates...
Is there any configuration in Rhythmbox to exclude a folder?
I only see a configuration for multiple folders in gconf-editor:

I've got a NAS running and I'd like to somehow make some of the folders and files invisible to certain users only. For example, if I 'ls' a directory, I want to see files 'a', 'b', and 'c'. But if another user does 'ls' in the same directory, I only want them to be able to see 'a' listed.I know I can use 'chmod +700' to make certain files not able to be read/written, but the filename would still appear in a 'ls'.I know I can put certain files inside of a '.hidden' file in the folder, but then it would be hiEdit : I'd also like to mention that the users that connect to the NAS could be coming from Windows or Mac operating systems. So hopefully the solution would work for users from those systems also..
View 5 Replies View RelatedI have a startup script for jboss (start.sh) that sets some JAVA_OPTS and then calls bash run.sh.If I run it (start.sh) from the command line it runs in the terminal fine. If I make a shortcut launcher for it in gnome and set it for 'application in terminal' it pops up then immediately dies after launch.Not sure what the problem is. Is this not working because one script is calling a second script? But then why does it work when I call ./start.sh?
View 4 Replies View RelatedI switched to zsh, but I dislike the completion. If I have 20 files, each with a shared prefix, on pressing tab, zsh will fully complete the first file, then continue going through the list with each press of tab. If I want one near the end, I would have to press tab many times.
In bash, this was simple - press tab and I would get the prefix. If I continued typing (and pressing tab), bash would complete as far as it could be certain of. I find this behavior to be much more intuitive but prefer the other features of zsh to bash.
Is there a way to get this style of completion? Google suggested setopt bash_autolist, but this had no effect for me (and no error message was printed upon starting my shell).
