General :: Bash Script Choice Menu From Csv File?
Jan 25, 2011
The script starts first a program I wrote earlier that collects specific data from 3 online csv files and write a summary csv file called /Tribalwars/request.csv . The seperator used is ;
the csv file looks like this but can be any number of rows (but not to many mostly 3 - 5)
Title1;tile2;...;title15;
B1;B2;...;B15
C1;C2;...;C15
D1;D2;...;D15
Now the next part of the script, and that is what I want to change, asks me to manually input some data I have to copy paste from the csv file just created. I mean if i choose to continue to do my calculations for city 2, I need to copy-paste C1 for the first variable 'cityname' , copy-paste c2 for the second variable 'xxx',copy-paste C3 for the third variable 'yyy',copy-paste C15 for the fourth variable 'points'
Then it starts new calculations etc, witch only these variables.
Now could it be possible to make a menu from the csv file with only the according cells on the screen and that I only have to choose a row from the menu?

I have a file called list.txt with on word on each line that changes in length. I'd like to make a menu, each line being its own choice. I pieced together most of it the only thing missing is a failsafe for typing a number out of range
Code:
#!/bin/bash
p=`cat list.txt | awk '{print$1}'`
[code]....

This morning I had 10 updates for my system including a new kernel 2.6.28-19 During install I was asked a question as to which menu.lst to use. I was completely confused as there was no documentation explaining the choices, so I took the default, keep my current menu.list. I did that because I have a modification to my menu.lst having added acpi-noirq I was afraid I would loose that and not be able to boot. Anyhow I ended up with my same menu.lst without the new kernel. So it booted the old kernel 2.6.28-18.Where is some documentation to give one some idea of which of the about 8 choices to make? I can't be the first with this problem. I have another computer to undate that has a different mod to menu list.I would like to know the correct way to choose the proper choice. If I don't get an answer I will try to document in more detail the choices.
I got around the problem by editing menu.list and copying the entries for 2.6.28-18 and changing them to 2.6.28-19 Many folks might not even realise they were running on the old kernel.

I installed Lucid Lynx in my p4:2.66 hz machine with XP sp3 pre-installed and the system booted just fine with dual boot option. Then I updated my Lucid. All updates were downloaded. But during update installation a power failure caused PC reboot. Again I started update manager and it gave me option for "Partial Upgrade". I did the same and it instructed me to reboot. The the real damn thing happens now when I rebooted, In the GRUB menu it showed only Memorytest options. I see no OS choice there, I tried to reinstall GRUB from live CD with mount options. And it showed no errors during the procedure. I rebooted but the same problem exists.

I recently installed Fedora 14 on an old Dell server (Pentium 4). It works fine, except that it somehow includes an extra startup step, in which I have to choose between two different grub versions. Here is the screen I get:
GNU GRUB version 0.97
Fedora (2.6.35.11-83.fc14. i686)
Fedora (2.6.35.6-45.fc14. i686)
Press enter to boot the selected OS, 'e' to edit the commands before booting, 'a' to modify the kernal arguments before booting, or 'c' for a command-line. I always select "Fedora (2.6.35.11-83.fc14. i686)" because I presume it is the latest version. Is there anything I can do to automate the choice of "Fedora (2.6.35.11-83.fc14. i686)" and avoid this extra step? On another subject, I have already modified the custom.conf file to eliminate the login screen step.

Yesterday I installed on my laptop (an IBM Thinkpad T42) "virt manager" using the Synaptic Package Manager. I'm running Karmic.
As part of the installation, SPM had me reboot the computer (which is dual-booted with Windows XP, which I use less than 1% of the time). The new GRUB screen came up showing two new initial lines, the first 2 of the following 4 lines:Ubuntu,
Linux 2.6.31-19-generic-pae
Ubuntu, Linux 2.6.31-19-generic-pae (recovery mode)
Ubuntu, Linux 2.6.31-19-generic
Ubuntu, Linux 2.6.31-19-generic (recovery mode)
When I allow the default choice of the first line to prevail, Ubuntu boots up into a condition in which the Wireless Network Connection fails to open, and in which nothing I've been able to think of makes it open.
If, instead, I scroll down to the third line (which was the initial default choice line, i.e., the default choice line prior to the "virt manager" installation), Ubuntu boots up into a condition in which the Wireless Network Connection operates as usual, viz., immediately.
Scrolling down works, but it would be better, it seems to me, to return to the condition in which the current line 3 either becomes line 1 or else becomes the default bootup choice.
I've used SPM to uninstall "virt manager", but the 2 new intial lines in the GRUB options remain. I understand that with Karmic's version of GRUB, viz., GRUB-2, it is no longer possible to change the bootup menu choices easily.
how I can either eliminate the first 2 lines in my current GRUB screen, or make line 3 the default choice?

I installed Ubuntu 9.10 (desktop version) and it performs flawlessly. Now I want to add a second hard drive to the same box, install Ubuntu 9.10 *server* on it, and use GRUB to control which one boots.
Problem is, I'm a Windows pro but a Linux n00b. Should I disconnect the first hard drive (the one with Ubuntu desktop) before I do the server installation on the second (new) drive? Also, how do I edit GRUB's menu to offer a choice between the 2 OSes?

machine boots straight to Windows, Grub2 does not display the normal boot menu choices. Therefore, not able to boot into Ubuntu 9.10.Perhaps someone could look at this Results.txt file and shed some light on what went wrong.This machine was working fine for a long time, then all of a sudden, it starting booting straight to Windows.

In Windows Explorer, if a file is focused, press Menu Key on keyboard, context menu will show on top of the file. But in Nautilus, the same action shows context menu where the mouse cursor is. That's a bit annoying. Is there anyway to make it work like Windows?

I've written a bash shell script (code provided below) that gives the user 4 options. However I'm having a little trouble with the code. Right now when they select option 3, to show the date.It loops over and over again.I have to close the terminal window to stop it because it's an infinite loop. How would I prevent this? Also quit doesn't seem to be working either.
#!/bin/bashe
echo -n "Name please? "
read name
echo "Menu for $name[code]............

I'm gonna setup a dual boot with Windows 7 on my system. My partition layout will be something like this:
Win7 -> ntfs
Ubuntu (root + home) -> ext4
Swap
Data (media & documents) -> ?
What file system should I choose for the data partition? If I go with ext3/4 it seems I can access them from Win7 using a file system driver, but it seems far from safe, from what google tells me. The driver installers aren't for Win7, and I need Ext4 without extents or an ext3-fs with an inode size of 128 to make it work at all. It saddens me to ask, but should I just go with NTFS?

I am supposed to take some small files, and print them to a specific printer, such that the small files are concatenated into one file. The file name has to be included in the file that gets printed.
Should I be looking to concatenate the files into one file with the file names included, and then print them?
something like: -printfunction -printername < file*

I was watching a friend of mine install PHP on SuSE with YaST, and it appeared as though he was able to select the various extensions he wanted compiled into PHP for installation. I didn't know this was possible, I thought you pretty much had to take whatever extensions whoever built the package decided to include. Is it possible with CentOS to install PHP with a custom selection of extensions?

just wondering what others are using to find and find and download new music. I'm also curious to know of other alternatives to Nicotine+, which I've been using for a little while. I've recently found a nice little widget called Seesu, which is great so far. It lets you search up bands and listen to their songs, and you can download the .mp3 for free afterwards if you like it. Anyway, enough of my pseudo-advertising.
What do you all do to find new music? Are torrent clients like Vuze the way to go, or is software like Nicotine+ better suited for the job? Perhaps you prefer the way of sites like Bandcamp, or by downloading from various online music stores. In any event, it'd be interesting to see how you all go about building onto your playlists.

How do I compare the timestamp of two files? I tried this but it doesn't work:
file1time=`stat -c %Y fil1.txt`
file2time=`stat -c %Y file2.txt`
[code]....
I printed both the time stamps, in order and it gives me
1273143480
1254144394
./script.sh: line 13: [1273143480: command not found
So basically if comparision is not working, I guess. Or if there is any other nice way than what I am doing, please let me know.
Edit: There was no space in between if, so changing it to this works:
if [ $file1time -gt $file2time ]

I have a file named file.txt with the following contents
Code:
19 man
24 house
44 dyam
90 random
I want to read the file into array and store each line in each index. I've tried using the following code.
Code:
dataarray=($( < file.txt ))
It stores each word in each index rather than each line in each index.
