I have a file with 5000 lines. it is a list of books authors, series and titles. all lines start with the author names, than there is a dash (-) than the series name, a dash again and the title of the book.
The problem I encounter is that sometime there is a series, sometime not, and as I try to enter this list in a database, I wanted to create a cvs file to import into mysql.
ex:
The best would be to be able to add in the second line, a "space dash space" just after the author name, but how to make sure it does not do it to the first line as well.
If I could separate all line with 2 dash, (grep ?) then I would be able to do a simple replace, and change the single dash into two.
To run a parallel chemistry program, I need to build the host list. The cluster already has SGE(grid engine) installed and it generates a host list file with the following contents:
The important bits are hostname(ex compute-1-1) and number of cpus to use(ex 2). And for this program, it wants them in this form, a shell variable: HOSTLIST=hostname:cpus=X hostname:cpus=X .... I've tried this script, but it doesn't work
I need to insert 3-4 lines of text to the beginning of a text file. The file is a largish MYSQL dump, the result of a backup shell script. This shell script should insert the required text.I've wrestled with sed, but lost.
I have to delete a certain line of text from the a textfile via ubuntu's shell scripting.I have done research, and it seems that most people advocate the usage of sed /d option. sed makes does not edit the text file. Hence, most options I discovered involved the use of a temporary variable/textfile and then overwriting the old file with the temporary new file. Is there anyway whereby I can bypass the use of temporary storage containers? I hope there is any magical combination of commands to edit the file directly.
I want to display something in my text view widget in glade using c code. that's all right. now I need to attach a save button beneath the text view.so that on click the text view content should save as a txt file..
I want to display the contents of a particular log file (simple text file, I mean in Linux). But there is a problem: The contents need to be organized in a fixed format. Have a look at this log file:
So, while displaying the contents of above file on a web page, I want to format the field names found in the log file: User Name:, Reported Problems Description:, and Remarks:. These fields may contain a variable length of text and no specific line number is assumed for them to appear on.
Well, what I am trying to do may sound wierd to some of you. The filed "Reported Problems Description:" can possible contain text which embeds colon (.
a sed command to add a text before line number in text file? I have text file with 500 lines, and i want to add 3 more lines with text after line 300, OR before line 302, isn't no problem.
How to list the contents of a folder to a text file. I'm trying to list all my music, including all subfolders, etc. to a text file, but I can't remember the command.
I have a text file with a long list of RPM's. I need to check if each RPM is installed. I'm sure I can cat out this file and run "rpm -qa" against it, but I'm having trouble with the syntax right now...
AKA "zipping on the fly .. the slow-as-molasses way." The list includes full pathnames to each file, and they're all in subfolders of the same parent folder (which, unfortunately, is not the root folder of the drive or system on which the files reside). A cleaned-up and radio-ready portion of the list looks like
What I'd like to be able to do is zip all the files in the list into a single archive, to avoid the step of having to copy them to the same location (presumably another folder on the HD) and then zip that folder. I'm more inclined to make provisions about extracting to a single folder at some other time. Is this possible in BASH, or would I have to consider a faster, more robust scripting language such as python or perl?
I'm sure I've done this before and am having a brain fart.
I have run into this a couple of time this last month:
I have a list of torrent files (blahblahhexblah.torrent) saved in a text file. I would like to read the text file and populate the client directory.
I can echo the file using:
But I cannot remember how to pipe the output into the directory, nor can I find any resources that describe the process.
Interestingly enough, I've had a couple of opportunities to do similar tasks with passwords and privileges and even across the LAN in the last few days. Solving this problem will help me solve the others for next time.
I am trying to create an array that will allow me to print a list after selection such as:
1) Location A 2) Location B 3) Location C
Would you like to print selected locations? Print I have no idea how to approach this problem and don't know whether Perl, Bash or shell script would be the most useful in this particular situation.
I currently have a set up in vim so that when I type "<leader>ns" it takes any given word and turns it into a sub "sub word(){}". I also have it when I type "<leader>nc" it creates a doc comment section that is "blank". I was wondering if someone could help me out with combining the two so that when I typed <leader>ns it would create the doc comments with the word already in the Subroutine: line and create the new sub routine aswell. I'm trying to understand what I have (downloaded from the internet) and only doing so so. Code:
" Put cursor over word and hit ,ns to create new Sub nmap <leader>nc o #------------------------------------------------------------------------------ # Subroutine: # Function :
I am trying to write a script to pick the directory name from a list of file. Here is a detailed picture.Have a file name LIST which contains the follwing for example/apps/oracle/product/test1/apps/oracle/product/test2/apps/oracle/product/test3I need a script that reads these line from LIST and creates foldersin /apps/oracle/product/test1/backup/date/test1 after reading the first line /backup/date/test2 after readin the second line/backup/date/test3 and so on.
i've been using some subliminal software on windows for a while now and have found it to be really good. It basically just flashes up a message on screen over the top of whatever is going on at that time but the message is only there for about 30 milli seconds
The message is not there long enough for your conscious mind to read it but the theory is that your subconscious mind will read it.It actually works really well. THe problem is that they dont package a linux version although they do have an OSX version, i'd really like this on ubuntu.
Tried it in wine and it installs but nothing happens after that. Alternatively perhaps somebody can tell me how you could get a message to flash up on screen based on a list of messages in a text file?
I need to get names of all installed packages in 2 machines and save them in 2 text files, then I want to compare these 2 files to know the differences between 2 files and from that I could know the differences between 2 machines. Is it possible to do that and what program I could use?
I can do multiscan documents using xsane and the scanner and create multipage PDF. My next wonderment was how would you create it so you can search for text in the PDF file. I am assuming the scanner is really just creating an image file. And the reader needs text? I did find a decent OCR web based solution. It looks like it would be a lot of work to put something like that together.
I need to create a script that returns a list of the users who have never changed their password from /etc/shadow. As I know on linux there is a command "chage" used for find last password change.
I'm working in a school and we have a Apple server, we have many problem with it. So, I would install a linux server instead.
Anyway, there is just one big problem (or I miss a simple tip to do it )
We have 1300 students. If I must create them one by one, that will take a lot of time. Actually with the apple server, we can go on a web interface & import an excel list with theses columns :
Due to this tool, I can upload an excel files with my 1300 students & a couple hours after, they have an account with a personal space & a shared space with their class.
My question is : This tool exist on Debian/Linux world ?
When I right click on a free area of the desktop or within an open folder, I read "Create Document" -> "no templates installed" and "Empty File". How to install the templates in there so I could open a file of my choice?
