I have been using comm to compare two simple column lists, and suppress items that were contained in the second list (suppression list). This was extremely simple and basic, however now list1 has two columns, and I must compare the second column in list1 with my suppression list.
Basically I need to compare my user list and suppression list to suppress any users that exist in the suppression list, then remove the second column (md5).I wasn't sure the fastest way to make comparisons if there was a similar command like comm, or if I needed to create an array of users and see if any of them matched the suppression list one by one. This seemed like it would be pretty process intensive. Anyone have any less cumbersome ideas?

View 2 Replies View RelatedI am trying to create a shell script, on taking a input file as parameter, which need to do 3 things
1) create a copy of existing file.
2) add a new line to the copied file.
3) strip off all the absolute paths inside the copied file
The first 2 points are straight forward. but i am finding it difficult to acheive the 3rd point. myself not very good with awk and sed. but gave it a shot in vain. For example, the input script consists of below,
PROGRAM=`/usr/bin/basename $0`
HOST=`/usr/bin/uname -n`
echo Start $PROGRAM `/usr/bin/date` |
/usr/bin/tee -a $LOG
The output of the script should look like,
PROGRAM=`basename $0`
HOST=`uname -n`
echo Start $PROGRAM `date` |
tee -a $LOG
on creating a new perl script which replace IP address from the text file. eg. If in a file, we found any word like 11.222.333.44 then it has to be replaced to XX.XXX.333.44

View 2 Replies View RelatedFirstly i'd like to introduce myself before I ask my question, i am currently studying a "Network Operating System 2" course, and in the syllabus the professor decided to use Ubuntu Linux for us. This is a first for me and I am truly greatly interested in the OS. It seems like a solid system once you get to know the deep foundations of it. The professor has already given us an assignment, but I feel its not fair as its just a bit too much from out of what he taught us .. He did not teach us what he is asking for. He asked us to create to a text file which lists the Sales from two Salespersons, and each one will have an amount for each month .. So 12 entries for each salesperson.
Using that text file, we should write a bash script which would read the values from the above text file, and produce a "Monthly Sales" text file, which shows the total sales of each month (combined from both the salespersons). I would like to ask for some guidance, some help on how to start. It's just that he didn't teach us any commands about this matter.
I have a few problem.

View 4 Replies View RelatedI've been trying to figure out a way to more easily color text in Perl like I do on Bash on a Linux box. In bash, what I'll do is set color variables up to equal the escape sequence, then echo out with escape seqeunces to print it exactly how I want it. Typically I'll want a character or a word in a different color, not the whole line. For example
echo -n -e "My face is turning ${RED}red${UNCOLOR} like a lobster." In Perl with the term::ANSIColor module, it seems to just do a line. Am I being dense? Is there a way that I can do it like I do it in BASH that's fairly easy to read after the fact?

I mainly need to do this on an ARM platform, so if I get sources I can cross compile it.
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.
I'm running Ubuntu Server 9.10 and every time that I su in as root and run a command, I get a little message after saying:

I am trying to write a Perl script that can open a file, find text that appears between two identifying strings (for now, "start" and "end"), then modify that text by enclosing it between "term_" and "_term" . Since the identified strings vary, the replacement string becomes "term_$1_term". From looking at other threads in this forum I've been able to get as far as spitting out the modified terms using the following code:
open FILE, "start2.txt" || die ("Could not open file <br> $!");
$text = <FILE>;
while ($text=~ s/start (.*?) end//) {
[code]....
The problem is how to get "term_$1_term" into the file in the same while loop, which I'm guessing would be some of variant of "$text=~ s/$1/$term/;" (which doesn't work as it stands).

If I use "#!/usr/bin/perl" in the beginning of a perl script the script won't work if the script is at all complicated. Simple scripts like "Hello World" works.
But if I use "#!/usr/bin/perl -w" in the beginning all scripts work?
If I don't use the -w this is whats in the logs:

Amarok is nice, and currently the only thing I've tried that will actually play audio from network shares and not lock up.

The general stipulations are as you'd expect; both files are of an arbitrary length, generally file1 will be larger than file2 but this is not guaranteed, the common lines (if any) will always be contiguous and only occur at the end of file1 and the start of file2.
I've got a setup where I need to use 'find' to find 0 or more files in a certain directory, however, 'find' always produces an error when there are no files that match a certain check. Is it possible to run 'find' while having it omit errors when no files match the pattern?

However, migraines from beating my head on the keyboard in frustration over Windows eccentricities led me straight to Linux. Linux blows windows out of the water, IMO.
Except for Media Players. I have tried every one in Ubuntu's software catalog. Rhythmbox is the only one that works, & it doesn't work correctly. I use my computer as my primary music source, & have saved nearly 200 albums/CDs to it. I transferred my collection to a memory stick, then tried to transfer it to Ubuntu. Rhythmbox 'accepted' most but not all albums, but none of the downloaded music, & lists the songs in each album backwards. When I open an album, sometimes Rhythmbox plays them backwards, sometimes (rarely) 'frontwards', but usually, jumps around, plays a few of the numbers, then stops. Occasionally, it goes through the collection, playing one song from each collection.
I was able to transfer the entire collection to 'Listen' media player, but it doesn't actually play anything, & I never even got that far with any other player. I have a two year-old HP Compaq Presario desktop w/ 500GB, (300 to Ubuntu & the rest to The Dreaded Windows for some stuff I can't run on Linux). I began with running Ubuntu 10.04 on 'wubi', then installed it from a CD I burned from the Ubuntu site. Someone suggested I had screwed something up during downloading, so I got 10.04 on a CD (w/ "Ubuntu for Non-Geeks"), but had the same media player problems. Last month I upgraded to 10.10, but still have the same problems.
