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?
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.
how to run a command on all files with the same extension in a directory like this:
Code:
tex breqn.dtx; tex empheq.dtx; tex flexisym.dtx; tex mathstyle.dtx; tex mathtools.dtx; tex mhsetup.dtx; tex xfrac.dtx;
but in a simpler manner? I found this: Code: find . -type f -name *.dtx -exec tex {} ; but isn't there something simpler?
When we view multiple files using less, how to go on to the next file? I gave these two commands:
Code:
[root@localhost log]# ls -lt boot.log*
-rw------- 1 root root 0 Apr 11 04:02 boot.log
-rw------- 1 root root 0 Apr 4 04:02 boot.log.1
-rw------- 1 root root 0 Apr 1 19:14 boot.log.2
-rw------- 1 root root 0 Mar 21 04:02 boot.log.3
-rw------- 1 root root 0 Mar 14 04:02 boot.log.4
[root@localhost log]# less boot.log*
This is what I got:
Code:
boot.log (file 1 of 5) (END) - Next: boot.log.1 <RETURN>
(END) - Next: boot.log.1
I could not view boot.log.2.
I wanted to add/modify a syntax highlight for g

View 6 Replies View RelatedI'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 liked the idea of the "cosmos" screensaver/desktop, but wanted to add my own pictures to the application. I navigated to /usr/share/backgrounds/cosmos and tried to drag and drop. I quickly found that I did not have permission to do this.
I googled my problem and found some command line tutorials telling me to sudo cp. My problem is that I have about 30 pics that I want to move in there, and I don't think I can just move the directory, they have to be in that folder as the pictures themselves.
I don't really feel like typing the cp line multiple times with multiple randomly named image files.
Is there a way to have the command line cp all of my files from one directory to another?

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 want to (from the command line) be able to counte lines in a bunch of files of a specific type in a folder and all its sub-folders. How would I do this?
View 1 Replies View RelatedI'm pretty sure this is doable from the command line, but my CLI skills have degraded a lot since my pre-Y2K admin days. The goal is to search all the files in the directory for a very long string of text and replace it with another string of text. The text being searched for is my Google Adsense code (which will be stripped from my website) and it will be replaced with a placeholder so I can easily tack something else in there in the future.
Seeing how I have that long snip of code on about 100 pages, automating the process would make life easier.
If I was searching for a single word, I can see ways to do this.
If I paste the code I'm searching for into a text file, is there a way to:
find (contents of oldstring.txt) and replace with (contents of newstring.txt)?
I'm trying to code the following WHILE loop in Bash:
While [string1 is non zero] and [string2 is non zero] and [counter < max]

I can't get the syntax right. I've tried:
Code:
while [ -n "$STRING1"] -a [ -n "$STRING2"] -a [$COUNTER -lt $MAX ]
But I get 'Too may arguments'
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.

I've been looking though different editors for one that has good printing support. Ideally it should be able to print C++ code with line numbers, syntax highlighting, multiple columns per page, customizable fonts and sizes and a print preview feature so that I can make sure it looks right before sending it to the printer. It appears that notepad++ had at least some of these features, but it is not available on linux. The best I could do so far is to copy/paste the output of 'cat -n foo.cpp' into oowriter and format it into two colums. I don't get synax highlighting though and I have to manually replace tabs with a few spaces as well as some excessive leading spaces before the line numbering.
