I have recently backed up all my documents photos etc to an external hard drive. What is the best way to check that everything has copied? I have tried diff but it was not very clear.
View 7 RepliesIf I execute the following command:
cp -R /myfiles /mydestination
If myfiles contains several sub-directories and files, in what order will they be copied? For example, directories might be named 0123a, 9993c, myfolder, xfolder.
They are not copied in alphabetical order OR in date order OR in the order they appear when using a standard ls command as far as I can tell, so what actually does determine the order?
Edit:
I am trying to determine the order that the cp command uses in order to determine how far along my copy command made it before it stopped. For example, I was hoping to be able to determine it copied 3 of the 4 directories successfully.

I just burnt a large no. of things to a DVD, and Brasero complained of errors. How do I check whether all the files on the disc are the same as the ones on my HD
View 3 Replies View RelatedI am in need of a way to check that the same file exists within two different directories using a filename as a variable. Here is the process which requires it: The script is reaches out (via ftp) and pulls down a file(s) and delete it afterwards. This is halfhazard because in the instance it doesnt pull down the file, yet still deletes it, we are up a creek. I am looking to pull it down to a temp location and then verify that file exists in the location in which it needs to be present to process before deleting it, adding a little extra layer for security. The script itself is finished.If I put a file name in manually it works perfect. I just need a way to pump the filename into the variable.

View 14 Replies View RelatedI 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 just wondering what is the difference between RES, SHR, and VIRT.
1) The VIRT always seems to be higher. Is this using the paging file system. (virtual memory on the harddisk, the swap memory)
2) Is the RES memory the actual physical RAM memory?
3) Is shared memory sharing memory with other processes?
4) Just a final question. As I am running on a HP Mini 210, memory and CPU is a resource I don't have a abundence of. So if was to compare for example 2 difference browsers i.e. firefox and midora. What should I brench mark between to 2 to find what one uses less resources?
I am writing a script, in that my requirement is, if all the fill types stored in one directory from that we need to separate different different directories based on the file types.
for example in a directory(anish). 5 different types files
1- directory
2- .txt files
2- .sh files
like that and my requirement is the (1- directory is moved to one new directory(dir) which we are given in the script)and (2 .txt files are moved to another new directory(test) which we are given in the script)and ( 2 .sh files are moved to another new directory(bash) which we are given in the scrip)finally the directory anish should be empty..using bash script.how it is possible !!
I am fairly new to Linux and was needing some help on a comparing more than 2 files. I am try to come up with something that would compare at least 10+ different files to a master file and give me an output of what is missing.
Example would be: a.txt, b.txt, c.txt, d.txt compare each of them to the master.txt file, than output the missing text for each file into new file.
I came across comm and diff commands, am I looking in the right place or is there a much easier way of doing this?
Is there a way to compare an array in a while conditions?
I have one array that contains the results of some search and if the script has found all the items, then it should stop, so my idea is to have a while loop � la:

I want to compare two files and display values unique to file1. I tried using comm but it did not give me useful outputs.
comm -2 -3 file1 file2 does not work
Similar threads provide matched content. What I am looking for is unique content.
Iam having the following two linux files.
[Code]...
Now i want the following out puts
1. similar nos in both the file 1 and file 2 > output= File 3;
2. In file 1, but not in file 2 > out put= file 4;
3. In file 2, but not in file 1 > output = file 5;
The command sdiff is giving output with symbols > < | etc, and the such output file is not clear and ready to print. I want to print directly the output files. AND ALSO TELL ME WHERE I HAVE TO WRITE AWK PROGRAMS AND HOW TO RUN IT.

How do you change the case of the letters in file1.txt to uppercase and compare with file2 all in one command?
Im trying to compare two files and I only want to display the user names that are in the first file and not the second.
So I have one file named final.txt (which contains every user name and only the user names in a list no other information)
Then I have another file Over1.txt (which only contains certain users that have different permissions This file is also setup differently with the user name and some information about the user after the user name.
I need a way to compare final.txt to over1.txt so that I will only display the names that are in final.txt but not Over1.txt

I recently had data recovered and it was sent back to me on what I think is an NTFS drive. I copied all the files over to a file share I have on a Linux box, that's ext4. Now I have that share mounted on my OSX machine, and I can't move or rename most of the files. However, in a couple cases I was able to rename a folder after the third try. Another time I was able to rename a folder once, but not again. All the permissions are showing up the same on the command-line -- I can't see any differences between the permissions on any of the files/folders. Note that I can create new folders and add files no problem, and then rename and move those all I want.
View 5 Replies View RelatedI have ran into a permissions problem. It seems that any file I have created with Fedora I can browse to in Firefox. I cannot browse to files that I have downloaded from the internet or copied locally across our network. I changed file permissions to 755 and 777 for these files. I even thought that maybe it was the php file content that was causing the issue. So, I copied the file content from file 2 into file 1. File 1 was the file I could always browse to since I created it in Fedora. I could still browse to file 1 after it had file 2's content.
I look at the permissions and they appear the same for both files. I am not sure why I cannot open the other files. I downloaded phpMyAdmin. I cannot hit any of these files in a browser. I also copied some files from a a backup location we have internally. I cannot browse to any of these files either. I used chmod 777 filename. Even after doing that I could not hit any of the files. I moved the files into my document root directory ( /var/www/html ) and I still cannot browse to these files.
I have two systems running on linux. system one is running with RHEL 5.4/X86_64 hardware, system two is running with RHEL 5.3/i686 hardware. One filesystem is shared from system two and mounted as NFS on system one. Now when i do a copy from local filesystem to the NFS share from system one,it shows as follows

-rw-r--r-- 1 xkinved rbak1 30 Mar 3 2011 king
But if i do copy with -p option then it shows right time stamp. Both machines are running with slight(minutes) different in time. Does this could be cause for this problem? The problem is happening while i do FTP from some other machines too.
I've been giving the task to go to a Linux console as root. and generate a ssh rsa 4096bit key, and copy the private key to a USB drive.
1) What command should I use here? ssh-keygen -t rsa -b 4096 ?
2) Do I need to append the new private key to the authorized_users file? Which file exactly must be appended there? Would this be sufficient?
mkdir -p /home/myuser/.ssh
cat id_rsa_LOCAL.pub >> /home/myuser/.ssh/authorized_keys
Should any special permissions be applied to this file?
3) Which file must be sent to my usb drive so that I can take it home to connect with?
I have iomega appliance, which is based on Debian distribution. There is an NFS share that I have created which is without password. Since it is without password, there are some viruses copied. I want to find out which IP address is the source of these files. In other words, I want to know which PC is copying these infected files on the NFS share
