Sep 29, 2010

I am having trouble reinstalling grub so That I can see both my linux and windows partitions in the cain loader. Originally I had ubuntu, then I installed window, this wiped out grub so I had to reinstate it, and that went ok. Then I tried to get fancy and install another Linux on my machine.

Jun 5, 2011

I am trying to create a shell script similar to ls, but which only lists directories. I have the first half working (no argument version), but trying to make it accept an argument, I am failing. My logic is sound I think, but I'm missing something on the syntax.

if [ $# -eq 0 ] ; then
for i in * ; do
if test -d $d/$i ; then

Fedora :: Create A Shell Script File With Two Functions - Bash Scripting & /etc/bashrc

Oct 6, 2010

how come I can create a shell script file with two functions, I can execute the file, but when running declare -f, the functions are not on memory, and when invoking the function bash returns invalid. In the other hand, I can copy & paste the two functions at the end of my /etc/bashrc file.... then I can called the function by name.... and the commands within that function run on my session. here is a print of all my bash packets:


Does Fedora has restrictions on shell scripting? I haven't touch bash in seven years, so if things have change on it I'm behind on it, and sorry for my ignorance.

General :: Bash Scripting - Executes A Few Perl Scripts - Create A New Array And Take The Hostname

Apr 4, 2011

I'm writing a bash script that executes a few perl scripts. One of the perl scripts that I need to execute requires two arguments with it. The arguments are stored in a txt file, each line contains a hostname and its corresponding IP address separated by a ":" (colon), the txt file looks like this below:


I'm not sure if it's the best way to accomplish this but here it goes. In the bash file, let's call it, I create an array and assign each line of the file to an element in that array. I then think I need to create a new array where I take the hostname (which is before the ":") separate it from its IP address and place the IP address on a new line just below the hostname (this way I can reference to it like $hostNames[$x] would be the hostname, and $hostNames[$x+1] would be its IP address). So the new array would now look like this below:

Programming :: Scripting/programming Challenge Mac/PC Interoperability?

Jul 27, 2011

some basic programming/scripting/etc. ability but I am not able to do what I now need to do. I would like to have a link on a website that when a user clicked on that link, one script or another would execute based on what operating system that person is using. To wit: If a Mac User clicked on it, it would run a terminal script and would set up a served printer for him; if a PC user clicked on it, it would run a script to set up the served printer on his machine, you get the drift. The printer is being served on a Windows Server 2003 machine, the users are NOT domain users, the print server is also hosting the files, scripts, webpage.

Programming :: Bash Scripting To Programming?

Jul 13, 2011

i'm in the process of learing C++. currently i'm creating shell scripts to get things done. i'm just curious how, as a programmer using C++ you would get a similar job an example i have a script that takes the contents of files, pipes it to some sed and awk commands, which is piped to create a new file. that file is then imported into a mysql database.if you were going to do this in C++, would you call the sed/awk programs to modify the file, or can it be done within the program itself? i'm probably jumping the gun here because i've just started learing about pointers so this is above my ability

Programming :: Bash Scripting: How To Keep Leading 0 On ' And '

Jan 27, 2010

I'm trying to put together a script that will quickly run through an archive directory of log files that are named by day of the month 01.gz, 02.gz, 03.gz.... 31.gz. The script uses gunzip -c | grep | wc to count up the total number of hourly occurrences of a filename and outputs the results to stdout.

The only snag I have left is the octal limit when it gets to 08 and 09. I've seen examples using perl and awk, but this script uses a number of nested for loops and if statements that I don't want to have to rewrite in a different syntax. I found that I can use num=10#08 to set that variable to a base 10 instead of a base 8, but then I lose the leading 0 again when it passes the number to the next filename variable.

Programming :: Good FTP Scripting Language

Jul 28, 2009

We have to (re)write a bunch of scripts to download files from remote ftp servers, where we won't know the names beforehand; move the files to an archive folder on the FTP server; copy the files to the correct servers on our LAN; and log the file information in Oracle.Our current scripts are for a windows product called ScriptFTP that provides a nice little language. It does everything except the logging, but we're wanting to get rid of Windows.

I have recently been given the job of maintaining the code, and I'm looking for a good language for simple, robust ftp scripts that will work on Linux. We have some customers with remarkably unreliable FTP servers. If necessary, I can write another program to handle the logging to Oracle. I'm usually a C++ developer, so a similar syntax is a bonus. I also want to be able to hand this over to an entry-level programmer later.

So far, I'm intrigued by PHP, but I've hardly had a chance to look at it for any scripting. I like the idea of being able to loop through the files individually and even be able to skip over anything that looks like it's currently being written (either based on the file name or date/time). I've thought about writing something in C++ that would take a simple config file instead of a full blown script. However, I don't want the maintenance, unless someone writes a quality FTP library that is inexpensive (hopefully free) for commercial use.

Programming :: Can't Seem To Find Scripting Tutorials

Dec 1, 2010

I am familiar with C, C++, and Python at a novice level. I have recently tried learning bash, but I can't seem to wrap my head around it. My biggest problem, I think, is the huge "vocabulary"-- it seems like there are thousands of commonly used commands, and several ways to use said commands.I've done some google searches but can't seem to find scripting tutorials that tailor to n00bs. Most go from basic "Hello World" programs to very complex scripts.

Programming :: VB Scripting Worklsheet And Key Events?

Jan 18, 2011

am working an a worksheet where I need to lookup id in an other worksheet.The script works as long as I am staying on the same row. When pressing key up or enter the corresponmding lookup information is not placed on the very same row.In short terms, I want the lookup data to be enterd on the same row no matter what key I am pressing.

The script:

Private Sub Worksheet_Change(ByVal Target As Range)
Dim cfind As Range
On Error Resume Next
If Intersect(Target, Range("A:A")) Is Nothing Then Exit Sub
thisRow = ActiveCell.Row


This example is set to Enter key procedure. So when the enter key is pressed, my current row will change by 1 so I have to compensate for that. All I want is that the data will be correctly enterd no matter what key I am pressing.

Fedora :: Sfdisk Refuses To Work - Says Sda Is Busy ?

Feb 26, 2010

I have 2 HDs, an old one with LVM (sda) with two partitions, sda1 and sda2, and the new one without LVM (sdb). I want to format the old sda device. I tried with sfdisk, but it says that the sda is busy:

But there is no call in /etc/fstab to sda, I did a /sbin/swapoff -a, and this is the output of df:

lsof tells me no one is using sda, sda1 or sda2.

So, why does sfdisk refuse to work?

Software :: Sfdisk Starts Partition From Sector 1 Instead Of 63?

May 1, 2011

Slackware 13.1,using "sfdisk".I need to use this one as it can be used in a non-interactive mode,"parted"is not a solution for me.Inside my own script I make the partition like this:


set `losetup -f`; dev=$1
`losetup $dev $out`
sfdisk $dev << EOF

However after formatting this single partition in FAT16 I can see the drive in my emulated Windows311, but not use it. It says that the drive cannot be accessed. When I do the same thing interactively with fdisk it all works. When inspecting the partitions in both cases via "fdisk -ul" I see that whenever sfdisk is used to create the partition it is created starting from the 1 sector. Whenever fdisk is used it is created from 63 sector (which is correct of course). How can I make my sfdisk start the partition not from the 1st sector, but also from the 63 so that OS wouldn't have problem with that?

I tried like this:


sfdisk -uS $dev << EOF

But it then just says that the partition does not end on the boundary. Trying to see the content with fdisk -ul says that partition table is incorrect. So doing it this way doesn't work.

Debian Programming :: Bash Scripting For Jessie

Aug 25, 2015

You are probably using systemd (check it with ps --pid 1) and therefore /etc/init.d isn't considered for autostart. Here can you find some information about systemd and autostart [1]. As far as I know systemd isn't intended to start applications with systemd. I recommend you to use the autostart feature of your window manager or desktop environment or at least the .xinitrc.

Programming :: Bash Scripting - Pointed In The Right Direction?

I know programming basics, but that's about it.Anyway, I have a program that I would normally run in this manner (note that I didn't create a permanent alias because I've been moving the program around a lot):alias dx='python /path/to/' dx A_input.dx B_input.dxSo, you see, program dx takes two input files, and 'A' must come before 'B'. I have a folder full of these types of files that I'd like to loop through with this program. They're named as follows:
