CentOS 5 :: Manipulating .ps/.pdf Files; Doubling Up On Pages?
Dec 19, 2009
I'd like to take a regular .pdf file (also converted it to .ps), and double the pages and switch it to landscape orientation. I've used the tools at the following website, but it doesn't exactly do what I want it to.[URL]... In particular, the left page is too far to the left, and both pages are too high up. Please see attached screenshot of one of the pages. I'd like to get this to work because then instead of printing 234-page coursenotes, it'll be half that. Does anyone have a good solution to do this?

an operator saved a file with a ':' in it, creating a file stream (new concept to me). I'm wondering if anyone with wisdom can point me to know how to get the data from that file piped into another file.. i.e. he saved as "wrong file: rest of wrong file title.wmv"
so first, can this be salvaged in ubuntu? ..how? ..
I figure I'd need the orig. hdd, maybe..:
Code:
cat "wrong file: rest of wrong file title.wmv" | cat > rightFile.wmv
dunno.. Am I grasping, or am I on right track?
this is for work, so I'm not at liberty to tinker & possibly mess it up more than it is.. the encoder's log also lists ":$DATA" after the rest of the file after the colon

I have a .csv file with a list of Drugs Name that i need to remove from the folder. The folder consist of files that stored as drugname.mol format.
What i need to do is to sieve out those mol files from the folder?
How do i
(1) access the drugs names from the .csv file line by line (variable x)
(2) how do i access the files in the folder one by one (variable y)
(3) how can i do a comparison whether $x.mol == $y
(4) and shift them to another folder if $x.mol == $y

I recently migrated to a newer server running centos5 and cpanel
I have imagemagick installed
I installed freetype as well
Most images display fine on web pages for accounts on the server, however, .gif images do not display.All I get is an image placeholder.
.png are fine
.jpg are fine
I have not tested all the possible varieties of images, but .gif I know is not displaying.I am sure its some kind of RPM I am missing or a configuration problem.

I am having problems in printing 'complex' PDF files. Simple pages are no problem. Good examples is Royal Mail postage printing. Generated PDF displays correctly - and in Ubuntu 10.10 printed perfectly. Since I upgraded to 11.04 I get a blank page. No matter what I do. I have tried everything suggested when I googled the problem - but no solution works. I am printing across the network through my NAS box (no changes to that at all) to an HP Laserjet 1010. It all works correctly and as expected under Windows - so the setup is fine with printer and NAS. its a problem introduced by 11.04.

We just recently started using Linux Ubuntu. I've been having trouble opening PDF files. I can open and close just a few PDF files one at at time, but then suddenly when I click on the PDF link, it opens up to a blank page. After that, all I get are blank pages

I have a performance report that provides all the information I need to report the following: total transactions per day, average transactions per second, and peak transactions per second. It just doesn't provide any of it in a very accessible manner, so I want to parse on it and just capture the bits I care about. Ideally, I'd like the output to look something like this:
Code:
Date Total Avg Peak
07/11/11 12,328,033 24.05 64
07/12/11 9,328,429 21.98 56
The problem is the format of the input file, which is somewhat complicated. The report gives a summary of all transactions within any given second, and then totals at the end of each day, with page breaks in the middle, like so:
[Code]...
So first, the easy part that takes me to the daily summary, which gives me the date, the total transactions, and I can divide the total by 86400 to get the average per second, too. No problem. It's the last part that's got me stumped... the daily peak. I can't just do a while loop on the date, because it's missing from most of the records. And it also means I can't use positional parameters, because depending on the page break, the total will move between $2 or $3. And I need the date as a conditional to find the daily peak, because this output will have many days' worth of data.
Any ideas? Some kind of awk or sed command to insert the date wherever it's missing (I'm not particularly good at either utility)? Is there a method to parse these things based on column location that I'm not aware of?

I've recently inherited a bunch of files at a new job and am trying to figure out some of the problems that have constantly popped up. The one i'm getting a huge headache with results from a bash script that is supposed to change a date format from a client populated txt field to one we want defined a certain way. Everything in the script works fine, except that one function. Below is the line i'm trying to manipulate, with date examples.
sed -e 's/.0000 EA/ EA/' -e 's/ 01012010 / 01-JAN-2010 /' -e 's/ 12312011 / 31-DEC-2011 /'
The one caveat is that the first date is non-static and changes daily. It is, however, always the current date. If it helps, the second date will always be a year away from the first date.My idea was to pull the current date via perl's DATE function, but...how to do it, and calculate a year away without throwing the rest of the bash script off? Any help would be appreciated. I'm sure it's a simple solution but i know absolutely nothing about these scripts and how they were written.

Running man, upon exit "erases" what man was displaying. I'd like to leave it up so I could scroll back through it. Is this a function of the PAGER or MANPAGER environment variables?

I have a Cent OS 5.4 32 bit final installed in my dedicated server.
I used to run lighttpd with php in my server until now and all was fine.But yesterday I changed my website which needs apache to run. So installed apache using yum install httpd command.
Then I added the virtual host name of my domain in webmin panel but when i try to run my php script in browser then its not opening php pages.
Instead it downloads php files like index.php when i open in browser.So I guess apache is not able to compile and run php pages. Only html pages are opening right now..

I'm trying to manipulate a large text file full of records (metadata - one complete record per line). I need to delete every line on which certain words appear - there are five different words, all pretty simple all-caps strings with occasional whitespace. I tried using grep -v, which worked a treat, but only string-by-string. Ideally I'd like to run this as grep -v -f, where the file targeted by the -f contains the strings I need to match in order to delete the lines they're in.
i.e. grep -v -f filecontainingSTRINGS.txt targetfile.txt > outputfile.txt
When I try this, however, I don't get any matches - or more specifically, no changes are made in the output file. It works fine if there's only one string in filecontainingSTRINGS, but it doesn't work if there's more than one (I'm using newline as the delimiter). (Also my machine doesn't recognise /usr/xpg4/bin/grep - no idea what that's all about!)

I am running OpenVZ.I wanted to use the VPSs IP at a particular port to load the Servers Web Pages e.g. The IP 88.88.88.88 is the VPS IP and 77.77.77.77 is the servers main ip.My files are on the main server at /usr/local/pages/
I want to load the page from the URL: https://88.88.88.88:8888
These should load the files from the main server at /usr/local/pages/ Virtuozzo a OpenVZ panel does it. So how is this going to be possible ? Will DNAT do the trick : iptables -t nat -A PREROUTING -p tcp -d 88.88.88.88 --dport 8888 -i eth0 -j DNAT --to-destination 192.168.0.1:8888

I'm very new to Linux, and I have ran a Windows XP server before, with a Apache2 Server software for Windows. and didn't have any problems with it, but I really want to set this server up with Linux.
The server is running, but the only thing that comes up in the browser, is the html pages, the pages call all the images from a folder /images/ but for some reason I can't get it to pull the folder up. None of the graphics show on any of the pages.
I also have a VirtualHost setup, and have another website set up in the DocumentRoot with the 2nd site, but it won't come up ether, even tho it is listed as the 2nd VirtualHost, and have that folder set up as the DocumentRoot.
I'm just using IP Addresses for now till I get this all sorted out.So if I enter the IP the main page comes up, just no graphics. if I enter the IP Address/2ndSiteFolder/ I get a directory listing with the 2nd site folder listed, so now if I click on the 2ndSiteFolderName, it comes up as IP/2ndSiteFolder/2ndSiteFolder/ Now the 2nd site comes up, and so does all the Graphics for that site, even if I go to some of the other subfolders site. So its just weird. I don't know what I need to do to get this to work right.
I know it has to do with setting up the folders for VirtualHost, I just don't know what it is. I have been working on this for a week, and I'm not getting anywhere..

Why does centos-release-notes have any dependancies ?
I can see no reason why centos-relese-notes should depend on centos-release when I try "yum erase centos-release-notes" I am told there are 72 dependancies including completely irrelevant packages such as tar all because of this unnecessary dependancy.
The centos-release-notes package simply contains a bunch of text/html files that nothing else relies upon, so why the dependancies ?

I am wondering what is the fastest way for me to move files from a VPS running CentOS to my home PC? I do not have FTP or anything like that installed. Are there commands I can enter in putty, for example, that will simply download an entire directory on the VPS onto my home PC?

I have a file of +1 1GB in size. I want to split it in either 100MB rar files or 100MB zip files.
Anybody know what command I need for this?
Please keep it simple, I'm very new to linux. So I'm hoping somebody can give me a command in the lines of "blabla "put file name here" "put file size here" "put folder to rar/zip" here.

Here is a dumb question (For some reason I can never remember Linux commands but can always remember DOS commands). I don't know what it is, but I think it's the "everything is a file or a directory" nature of Linux that I can't remember it.
Anyhow, I have an instance running on Amazon EC2. I have noticed recently that FreePBX (an Asterisk GUI) is warning me of shortage of disk space. So here is the output:
[root@ip-10-251-123-3 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 9.9G 8.8G 621M 94% /
/dev/sda2 147G 188M 140G 1% /mnt
[Code].....
So, it seems that I have a lot of space in sda2 but I don't know how to access it. how to do a symbolic link (or I can search with google) to move some folders to sda2 and then link them.
