Software :: Vim - Command Input For Creating Syntax Files
Jan 25, 2011
There is a syntactical feature I would like to see in Vim, and so I thought to write myself a syntax file for my needs, but I am having trouble finding the exact type of syntax highlighting I want to incorporate'emulate. Currently in Vim, from the terminal instead of say gvim, when I place my cursor over a parenthesis or brace, the corresponding brace or parenthesis will highlight, or block its character. In my case, instead of a single character they will be full words specified within the syntax file.
I want to do something similar. For example if my document has three words:
Group
Element1
Element2
I want the syntax file to tell Vim that when I have my cursor over the word Element1 or Element2 that Group will become highlighted. In the same, to have the cursor over Group will cause both Element1 and Element2 to highlight. I have looked here but understanding still eludes me: [URL]. I would also be happy with creating some sort of command input, where I type in the group name and the elements highlight. Like a very specific search function that searches for only and all instances that are contained within the group named.

I have a program I use, rrdtool. I need to modify a ds value on every file at the same time. However, using a wildcard (*) to try this operation of all files does not work and instead only updates one file.
Here is the command syntax:
rrdtool tune <file> --maximum traffic_in:100000000000 && rrdtool tune <file> --maximum traffic_out:100000000000
So, how can I do this on every file in the directory?

I'm trying to create an iso file in a terminal with the following command:
$cat /dev/sr0 > nameofdisk.iso
I get the following error
cat: /dev/sr0: Input/output error
I already checked and my optical drive is indeed /dev/sr0. I've hunted google a few hours trying to figure it out. Does anyone know why I'd be getting this error?

I am trying to find out can I use the ls command to list my wav files in such a way that it follows this format: <OPTION value="/home/filepath.wav">My first file </OPTION> I would like to know if there is a way I could simplify this because I have about 100 wav files. They all have names and if I could get them listed then a space then the name again with something behind it I could use the find replace feature to generate a bunch of links . If not is there a script out there that could use this format to generate links under this format? BTW this is for a pull down menu that would control windows media player

I'm currently studying for my Linux+ test and I'm getting conflicting information regarding the rm -rf command. Yes, I know this a dangerous command, but my question is in regard to how the command functions. In one book I'm studying it says that rm -rf / home/myfolder (there's a space in there) will delete the entire root directory because there is a space between the root and home directory. It says that if there is a spacing such as this, it will ignore anything after the space, so in this case, it would delete the root directory and stop, not that there would be anything left anyway. Then in another book I have, it says that if you did a rm -rf folderName / (with the intention of adding the trailing slash to indicate it is a directory and not a folder) it will delete everything in folderName (assuming it's a child directory of your pwd) and then CONTINUE on and delete the root directory. Now, those two statements contradict each other. When you remove a directory, does the command line ignore anything after a space or not?

I have a couple of files which follow this syntax:
*_yyyy-mm-dd_hhhmmm.*
Example:

*_2010-01-01_01h10m.*
*_2010-01-01_02h10m.*
[Code].....
and delete the others. or maybe move them to a subdirectory to be safe...

When ever i open vim, i get the error that the following error: E484: Can't open file/abcd/configFiles/vim/syntax/syntax.vim There was a .vimrc file in my home folder that i have removed.
Still i keep getting the same error. Presently in my home folder there is no .gvimrc or .vimrc file.
But still i keep getting the same error. I am not too sure where this file is mentioned.
Background info: The SHELL has been changed from tcsh to bash Earlier i had created a .vimrc file in tcsh, i have removed the .vimrc in bash SHELL.

I'm having a problem with sed syntax. So far I can sed the HiResBoundingBox to capture the images I want and output to pdf. But now ever so often I get an illustrator file that has hexadecimal values at the start and end of the file. Imagemagick powers through this and still creates the rastorized previews I want but the gs dies using the epstopdf script to output the vector files. If I hand remove the hex on both ends of the file, both functions work fine and the file can still be managed in illustrator but if I resave it the hex comes back. It only happens on a few files plus it seems to serve no purpose as the files work perfectly without it. I cannot get the sed statement to work. I've tried a blue million variations with no luck. Copied some that I found, same result.
Start of bad eps file:
ADOÆ ^@^@^@5O
^@^@^@^@^@^@^@^@^@UO
^@im^K^@yy^@^@%!PS-Adobe-3.1 EPSF-3.0^M
The way I need it to look:
%!PS-Adobe-3.1 EPSF-3.0^M
End of file the same:
%AI9_PrivateDataEnd^M
@ @
just needs to be:
%AI9_PrivateDataEnd^M
Tried
sed -n '/%/,$p' < = blank file
sed -i 's/%/,$!d/g' = same
sed 's/%/,$!d/g' = same
sed 's/%/,$!d' = same
I can't seem to find any proper reference to this.

I'm trying to backup a whole startup disk to another with GRSYNC but I don't need some files or directories. For example, I don't want to backup my 'swapfile1' (I do not have a dedicated swap partition) or the 'media' directory' in order to no enter a looping sync.I've searched the web for the correct syntax of the --exclude command but none have worked if applied in the advanced option "before" rsync starts. These a sample of NOT workin syntaxes:
exclude /media or -- exclude 'media' or -- exclude "media"
same for swapfile1:
exclude swapfile1 or -- exclude 'swapfile1' or -- exclude "swapfile1"

I have a latex code file which links itself to many other latex files. The syntax is as follows:input{*path of file to be inputed*}The path is relative to the current working directory, so if my file is stored in /home/kevin/mybook.tex and I want to include a file in /home/kevin/latexstuff/copyleft.tex I simply write:input{latexstuff/copyleft.tex}
The latex compiler includes these files just as if they had been copied and pasted into the main latex file at the point specified. My problem is that I have a document which depends on quite a bit of these input commands,ut I am trying to use a latex preprocessor (ratexdb, adds database fields to your latex documentshich does not support input commands, leaving my file only half processed.So I was wondering: is there any easy way to parse through my main file, detect only the input commands, interpret the syntax and include the files specified (where specified)nd produce a second, populated file, which can then be processed by ratexdb?

I am a Novell (now defunct) CNE tring to learn Linux and am having a lot of trouble finding out where the WB 6-6 is wrong in the syntax for adding local4... the the syslog-ng config file. In the instructions there are discrepancies between commas and simi-comma, they are both in the statements in no particular order. there is no pattern to them. Here is what the book shows:
filter f_local4debug { level(debug) and facility(local4); };
When I try to input this in the Gnome terminal window to try and find out where it goes wrong I get the following: -bash: syntax error near unexpected token "(" If I can get the correct syntax I belive I can use the info to get past the rest of this portion of the lesson. I am desperate to learn Linux as the only jobs out there for a Novell CNE are migrations to MS, which really sucks, since MS really really sucks.

Is it possible to create a new command prompt in Ubuntu? I have a assignment and I don't fully understand it. I have to make c files and then open them in the command prompt. Would this happen in a new command prompt or I'd have to use the already existing one? Is this even possible?

It has been happening to me since I started to use this laptop from the company for a linux test bed. Several times a day, when I do something from the command line, for example running an application connecting to another host on the internet, etc,it comes to a freeze and does not come out of it. I can not do anything else than a forced reboot from the power button, because the keyboard and the mouse do not respond. This work laptop is a lenovo W500, running on ubuntu jaunty, release 9.04. I have not encountered this problem before with my personal laptop though. My person laptop is a lenovo X61s, running on ubuntu karmic, release 9.10Should I reinstall the work laptop with some other version of ubuntu? Could it be some hardware problem ? What tools should I use to diagnose

I would like to ask the following:
1) ls -l |grep test -> this will grep every "ls -l" output line
2) ls -1 |xargs grep test -> this will grep every single file with test
3) ls -1 |xargs echo -> this will echo directory list
4) ls -1 |echo -> this does nothing!!!
My question is: how some command can receive input from "both sides" (grep can grep whole output or every single file - xargs, the same is for i.e. wc command). 4) echo does nothing (it's a single echo command).

Since 13.37 I notice that vi needs the 'home' key to switch from input to command mode. I think this is only when I connect via Putty to the machine. When I am on local console it is still ESCape like it used to be. Does anyone know how to set it so that vi will switch from input to command mode using the ESCAPE key when using Putty?
Another vi question :
When you edit htm files, vi goes automagically into some sort of html display mode. Ofcourse I never want that since all I do is edit the html in vi. So I need to go to command mode and type :normal everytime I want to edit html files. Where can you configure that vi (or vim) default to normal mode always?
<I see that vi links to elvis : >
# ls -al /usr/bin/vi lrwxrwxrwx 1 root root 5 Oct 3 2009 /usr/bin/vi -> elvis*

I am looking into creating my own terminal command from scratch. I researched online for some information on this subject was only able to view stuff related to OS X. I understand that they are both Unix based, are they both similar in creating these commands? Basically all I would like is for someone to point me towards the right direction to start or complete this task.

d* The user's NIS or LDAP group.
e* The user's home directory.
Which is the correct answer? I have my own thinking which will be explained later.
