I want to take a graphics file and make 10 copies of it to the same directory, each with 001, 002, or some such designation at the end of each file name so they have discrete files names. Is this possible using cp?
View 12 RepliesIn debian/ubuntu I want to:
a) Create a list of all the files in one directory tree
b) Do the same for a second directory tree
c) Compare the two lists such that, only the file NAMES are compared (i.e. just comparing the "file.txt" part so that "/home/folder/file.txt" == "/home/secondfolder/folder/file.txt)
d) Output a list of all the duplicates
How to do this using scripting languages or regex or something?
Was wondering if any perl guru's could help me with a quick log file adjustment. I have a text file that looks like so (tabs and newlines are revealed so you can see what separates the data):
There are maybe 100 lines of text in this file at any given time. I need to delete all duplicate lines only looking at the first bit of text prior to the first tab. It doesn't matter which one gets deleted as long as there are no two lines that begin with that same text at the beginning before the first tab. So in this example, either the fist line "1234" or the last line "1234" would need to be deleted. I already have code in my script that opens the files - I just need the code to read the text into an array and the part that would find matches based on the above criteria, and make the deletions.
If it would be easier, I can even do a system call and use SED (v4.1.5) and/or AWK (3.1.5) instead.
Is there a way to remove duplicate files from a specific folder through SSH? I've uploaded a lot of flash games on my server and I can see in the Webmin's file manager that I have many duplicates. Their names are different, of course.

Code:
chkconfig --levels 235 mysqld on
/etc/init.d/mysqld start
I can copy and paste this in Putty, but what if I want to manually type it? If I press return, the first line gets processed, so how do I insert a new line?

So, I usually write/find a test case generator for any code that I write. This type of code generally leads to some file output. To be thorough, I try and generate many different files to test my code on.
Say the command is like this:
Is there a way to automate this for many different values of the parameters and generate many different files?
I tried:
I wasn't able to use the $i in the filename, and without it the command gave me no errors, but did nothing else either. I know the Unix command line is very powerful, and I have a feeling that this should be possible, but I just don't know how to do it.
I need to write a script that will take 1 command line argument. The argument will be a username. The script will determine if the user exists on the system and will print an error if it does not. If the user does exist it will determine if the user is currently logged in, if the user is not logged in it will determine the last time the user logged in and display the file in the users home directory that was most recently modified.
View 2 Replies View RelatedIt has been such time that I have been making back-up copies of my DVDs using dvdrip. Lately I tried to back-up DVD of Iron Man2 and was surprised to see so many titles under Table of Contents. 93 titles of which re all running 2 hours plus. And so I ripped the recommended one which is the longest running title. Surprisingly, the output is all screwed up. Meaning scene one is at the end along with some scenes from the middle of the film and so on. Is there any way to correctly choose which of the 93 titles is the right one please? Obviously, I can't go through the motions of doing it one by one. Or would it be more practical to just copy the whole DVD image and burn in another DVD instead of making a HD back-up?

As an example, I have two servers, sm-i222 and fileserv. sm-i222 is a Win2k3 system running cygwin. fileserv is a linux box running RHEL 4.7. sm-i222 maps /cygdrive/c to the c: drive and /cygdrive/d maps to the d: drive(actually a single 4TB RAID). from the sm-i222 server /cygdrive/c I call a small script from the crontab. The internal IP for fileserv is 10.0.0.7. See below.
cd /cygdrive/d/fileserv/home
rm -rf /cygdrive/d/fileserv/home/*
rsync -avz -e 'ssh -c blowfish' root@10.0.0.7:/home/* .
These three lines perform well in that they make a full transfer of the fileserv:/home/ directory on fileserv to the appropriate place on sm-i222 using rsync. I use rsync instead of scp because I have to traverse subdirectories and symbolic links in the /home/... filesystem on fileserv. What I'm looking to do is use rsync to do an incremental transfer/backup of only the files that have changed since the last full backup. I'll manage the times I do this manually or in crontab. A colleague says this is do-able, but not how. Rsync.org says this is do-able but not how. Cygwin says this is do-able... see rsync.org. I believe what I'm looking for is a single rsync line like I have above that only transfers the changed files on fileserv to sm-i222.
I'm using a java application that runs as an interactive command line (in a terminal). My problem is that it's rather unfriendly as an interaction mode as it's minimalistic: it doesn't allow going to and fro with arrows, there's no history and so on. So I have to type all commands every time and have to retype it if I missed something at the beginning of the line, or I have to copy and paste from a txt editor. The strange thing is that I have seen the same application running on a Windows box and allowing for all the sugar. So I'm not sure if it's because of the shell script I run (as opposed to the .bat) or whether it has to do with system or profile settings in my shell.
For information, the shell script starts with:
Code:
#!bin/sh
I've replaced it with:
Code:
#!bin/bash
In hope I would have something closer to my normal terminal. The app runs but it doesn't change anything to the interactive mode. I'm rather clueless regarding sh/bash and so on. I've seen the manuals but I'm not entirely at home understanding and using their options. I know that there's a .bashrc and perhaps something like a profile somewhere, but I don't really know how to do things with these without risking messing up.

There are a few files on this Debian computer that I want to transfer off, to a networked computer, but I have no idea how to do this.
The destination computer is a freshly re-setup Mandriva install, without (as yet) samba. I don't think it's necessary though. The Mandriva install works fine, has graphics, etc, but can't see the Debian Squeeze computer on the network, possibly because it's in single user mode, thus prompting the problem of how to transfer the files, using only a command line.
