General :: Bash - Mirroring Of Multiple Directories - Hard Linking
Apr 11, 2011
I have 5 FTP users that upload files (and subdirectories) in their home directory, i need to mirror theese directories beetween them and with a "master" directory (accessible from a 6th user). Files can contain spaces or others special caracters. All the files are in the same filesystem, and i want to use hard link because i don't want to waste 5 time the space of a single file. I tried with find but i cannot handle spaces in it.
I have written an init script which I have kept under /etc/init.d, I need to create links to the directories rc0.d, rc1.d, rc2.d, rc3.d etc.. So that I can use chkconfig command to control the starting and stopping of the script at specific runlevels.
I want to make a webserver with multiple users allowed to login through SFTP to a specific folder, www.Multiple users are added, lets say user1 and user2, and all of them belonging to the www-data group. The www directory has an owner www-data and a group www-data.
I have used chmod -R 775 on the www folder, but after I try to create a folder test through my SFTP server (using Filezilla) the group of the directory created has only r and x permissions, and I am not able to log in with the second user user2 and create a directory within www/test due to a lack of w permission to the group.
I also tried using chmod 2775 on www directory, but without luck. Can somebody explain to me, how can I make it so that a newly created directory inherits the root directory group permissions?
I need a script to copy music from a network drive to my local disk. I require the script to auto mount the remote server, then to create the directory path to the mp3's I have a list of all teh songs in the following format, note some have spaces.
\7800SPARE4UsersPublicMusicSample MusicKalimba.mp3 \7800SPARE4UsersPublicMusicSample MusicMaid with the Flaxen Hair.mp \7800SPARE5UsersPublicMusicSample Song Sleep Away.mp3
I can use the following to mount the directory:
mount -t cifs //7800SPARE4/Users /dest-o username=user,password=pass
I'm thinking the best way would be to get the share name 7800SPARE and the grep for all these in the list, then mount it and do a while read LINE However I would need to creat the folders, I am unsure on how to do this. I think I would need to sed the backslashes to forward ones and then use rsync? Then unmount and move on to the next ones, if I can't mount the share It would be nice to log it and skip it.
I have a wide area network with 7 CentOS servers running Bind and 1 Windows 2003 server. All 8 of these servers handle DHCP and DNS at their respective locations. At each site I can ping computer.site.company I'd like to be able to resolve the dns names from site to site. So from site1 I would like to be able to ping computer.site2.company and get a response.
I need to create subdirectories in about 300 existing directories - the subdirectory will have the same name in all 300 existing directories. How do I do this using the mkdir command using a regular expression or globbing?
I am trying to exclude multiple directories when using tar. I can do it for just one directory with exclude= directory.I can also do it for multiple directories by typing that code again and again.As you can see im trying to call this variable that has endless amounts of directories in it seperated by a space.. but when run it doesnt work! It will however work if i just put one directory in the variable. Any ideas?
I have found ways to tar a directory and exclude certain directories but is there a way to simply tar multiple directories (they are in the same directory) in to one .tgz file?
I am using Ubuntu 10.10. I have a system set up with 1tb HD. I also have another 1tb HD which I'd like to use to mirror the other drive. So if the primary HD fails I can boot and operate from the mirrored drive. I've read that this is possible by using Raid. however I am confused if it is possible to set-up with a HD which is already set-up Ubuntu system. Also what what I can make out the mother board does not have a raid option.
I'm very new to working with the terminal on my macbook pro and am trying to understand how to navigate into certain directories with it. I can't seem to get out of my username directory. I'm trying to access MAMP/htdocs and get those files into my git repository. I'm new to all of this. I am typing and getting this: David-Adamss-MacBook-Pro:~ davidadams$ cd Applications/MAMP/htdocs/barcodes -bash: cd: Applications/MAMP/htdocs/barcodes: No such file or directory I need to get the "davidadams$" out of that line but I don't know how to navigate out of it.
compiling and linking using gcc: What does a file name with a suffix '.a' represent? If I have multiple .c and .h files, how can I link them together? How can I create the .a file?
I tried to link my executable program with 2 static libraries using g++. The 2 static libraries have the same function name. I'm expecting a "multiple definition" linking error from the linker, but I did not received.
Code:
//staticLibA.h #ifndef _STATIC_LIBA_HEADER #define _STATIC_LIBA_HEADER int hello(void);
I have one file called test.sh and in that file I have the below code. All this code is, is paths to three directories (as you can you can clearly see!).
Code: #!/bin/bash BACKUP="Documents /bin /sbin"
Now I have this other file which reads the directories (by using $BACKUP) and creates a tar file of everything in that folder. But what I am unsure of what to is create a bit of code that will simply look in test.sh, read all the directories and print a line saying either they all exist or some are missing. If possible it would be good to know which directories are missing too!
I have fiddled around with using -d but I can only get it to work for one directory or manually having to write out each directory.
I have 60+ directory's each containing multiple .doc files. I need to move them to a single directory and keep their file name intact. I don't think cp will do that with out listing all the file names. I was thinking of something like: cp -r /dir/*.doc /newdir . Or should I use a combo like find -type *.doc|cp /newdir?
I found a script on webmaster world that mostly does what I need it to, but have been making modifications to tailor it to my specific needs.I know that //..*/ tells awk to ignore hidden directories, how do I define more directories to ignore? (i.e. temp, var, etc)? I've tried playing with prune before the awk command with limited success...I know that there are many ways to do the same thing and keep running into brick walls.
I have hundreds of directories in various subdirs that I need to remove. I want to remove all of these dirs, but can only find solutions on how to do remove files (or how to remove subdirs from within the current dir).
I think I need something like
find -iname 'testfile*' | xargs rm -i
where I want to remove every directory that contains the word 'testfile' within the directory name. I know xargs wont work for dirs,
I'd like to move a selection of files from all the sub-directories within an overall directory to a single destination. I don't want any of the directory structure, just the files themselves. This is what I tried so far:
mv /dir1/*/igs*.sp3.Z /dir2
There are other .sp3.Z files in the * directories within /dir1 but I just need the ones that start with igs..
I have 3 c++ files, classdef.h (header file with class definition), methods.cpp (class methods) and program.cpp - the program itself. Both .cpp files have
Code:
#include "classdef.h"
in files. How I can link the files together and compile them in one executable program? I am using Geany IDE for coding.
I'm not sure if this is possible or even where to start. I assume that this can be done with an sh script using tar or similar.I have several very large zip files that contain images for all of the products in my online store. Each image is named after its 13 digit SKU (for example, 9987788000012.jpg). In order to import products into my store, all images are placed into a media directory. Unfortunately, there are over 100,000 images.
So I would like to break the images into sub-folders based on file name. For example, when I extract store_images.zip (or tar or whatever), my extract script would create directories (if they don't already exist) based on the first three digits of each image name, placing each image into the appropriate bottom level directory. For example, "9987788000012.jpg" would be placed in the following directory "media/9/9/8", with media as the root and "8" as the directory that holds any images that start with "998". Perhaps two sub-folders would be less cumbersome.Assuming this requires a script, particularly since it involves scanning image names, creating folders, and saving images to specific directories, which language would serve my needs best? PHP? Has anyone had to do something similar?
I am attempting to copy a set of sub folders from their multiple parent directories to a new location.
For example, I have three folders to copy:
I would like them to be copied to:
In actuality there are many folders besides folder1, folder2, folder3, and no numerical order exists. So, the folder named 'photos' would be copied to its parent folder's name in a new location. I would need this to occur for all folders in the '/home/user' directory.
Description: I am a newly appointed system engineer taking care of linux servers. We have a new set of data coming in which need below configuration: How to do a script with function?:
for files with ".txt" in sm copy each of the files to folder : sm1 and sm2 (log every copy) if succesful: remove original log into the log file if not successful: (not successful copying 1 particular file to all the folders) retain and retry log into the log file mail out the admin with that particular file name
I have already do try a bit: cd /export/home/ for dir in sm1 sm2; do cp -p sm/*.txt $dir/ done Is my starting right? How to do the rest parts?
So me and my friend our on my network and we have done a bit of hacking and have managed to get music off of pandora and have it sort it by forlder /media/...../artist/album/song and it won't redownload a song that we have already downloaded (this is done by our code that we stripped from pithos and modified a bit) also we wrote a bash script that renames all of our files correctly and tags them with .mp3
I was wondering if I could link our two hard drives to make sure that we aren't both downloading the same songs. I am also having issues getting my external accessible on the network i have it formatted to use a FAT32 file system.
I have written an OpenGL based program which uses i.a. libjpeg that I want to link statically so I can send it to someone who doesn't have all the libraries needed installed to allow for a dynamically linked executable to run. As such I tried with giving the [b]-static[b] parameter to gcc.
pls suggest me how to mirroring two hard disk drive in rhel9 server.i can do raid on those hard drive but user requer mirroring.so pls help how could i do this, mirror two hard drive.
I need to replace ":" from multiple files names, since I am going to copy those files from a linux partition, which admit the ":" to a FAT32 partition, which does not.
Example: original name: eg06_ana_21-05-06_09:21:03.JPG wished name: eg06_ana_21-05-06_09-21-03.JPG
I have googled a lot but I have not been able to adapt the examples given by people to my aim.
It seems that rename command is what I should use, but I have no idea to build the correct pearl expression.
