General :: How To Compare Two Columns In A File

Mar 29, 2010

I am trying to write a script which compares a log file with reference file. The log file has a table, the LHS of the table are constants strings and RHS of table values changes if there are any changes in configuration.code...

Here I am looking for a script which compares test.log file ( whose RHS data-types are known prior whether it is digit or string) with test.Ref which is reference file for test.log file. It will be really helpful for me if any of you give some idea about writing this script.

General :: Compare Columns Of Uneven Length?

Jan 20, 2011

I have a text file with 2 columns. Column A has 69,000 rows. Column B has 49,000 rows. Column A has our complete product list Column B has product list from Manufacturer 1 There are only certain/some rows which are common between 2 columns. and also, column B is not a subset of column A. Column A has extra entries and so does column B. I need to know, which rows from Column B, are common with Column A which rows from Column B are not common with Column A. Essentially I want to know from this list, how many of our products are from my manufacturer 1, how many does my manufacturer has which we dont carry.

How would I acheive this? My natural approach to solving this kind of obstacle is to reach for MS excel and use its lookup function, but its not working... Its taking forever and hanging up. since the file is so huge and probably my excel skills are really bad.

How can I do this from command line? I am looking for awk command if possible instead of sed since I am trying to pick up its syntax and usage etc. My thought process is, sort column A,B, for every row in A, lookup and output based on condition. Dont know if I am on the right track.

General :: Bash Script To Read Csv File With Multiple Length Columns

Jul 27, 2011

I've searched everywhere and I can't come up with a good solution. For each line I need to find the average, min, and max. I've seen plenty of solutions where the number of columns is fixed, unfortunately for me these lines can get pretty large. My thought was to read each line individually into an array, loop through the array and find the avg, min, and max that way but i haven't had much luck. I can read each line using a while loop but I'm having trouble with the array part, or perhaps that's not the best solution?

General :: Compare File Timestamp In Bash?

May 6, 2010

How do I compare the timestamp of two files? I tried this but it doesn't work:

file1time=`stat -c %Y fil1.txt`
file2time=`stat -c %Y file2.txt`


I printed both the time stamps, in order and it gives me

./ line 13: [1273143480: command not found

So basically if comparision is not working, I guess. Or if there is any other nice way than what I am doing, please let me know.

Edit: There was no space in between if, so changing it to this works:

if [ $file1time -gt $file2time ]

General :: Compare Two File - Information About Software ?

Nov 16, 2010

I have many files with info about soft, installed on remote machines.

I need to compare this file with template (soft than must be installed) and output file must content info about software that's not installed.



output must be software_name2, becouse it is not installed, but software_name3.2 is good enough becouse version is more than we need.

So, the task is to show lines that is in template and not in source, using simple regular expressions

I use grep




But it shows me only lines that is in source and not in template etc...

OpenSUSE :: File Manager View Properties (in Details Columns)

Mar 1, 2010

I am newbie in openSUSE as still in transition from windows OS. How to display file properties (details other than size, date, permissions, owner, group,type) using file manager applications similar to Dolphin, Konquerer, etc. I have heaps of files ported from windows environment where I used to store descriptive subjects in one of the file properties field. In windows environment, I would have used file manager such as explorer to display the selected file properties field when searching for particular file before opening it. I know openoffice supports the file properties feature but unfortunately it would appear Linux OS currently does not have a file manager application ready to display these information.

Programming :: [Perl] Fail To Sort A File With 300,000 Lines By Multiple Columns?

Nov 10, 2009

Each line of the file I am sorting is in the following format:

<url> <month> <day>

For example:


I wrote the following to sort:


$in = shift;


The script worked fine for my small testing files, but failed in my input file. The input file is 18MB and containing more than 300,000 lines. The output will contains some lines like that:

url_one 10 1
url_two 10 1
url_three 10 3
url_four 10 1

Is that because my file is too big for perl to handle ?

Programming :: Reading File And Compare In Bash Scripts?

Dec 9, 2010

how to program in bash, an i have a problem, i am trying compare values in between 2 values (from another file), so far my solution is to make a nested for loop, but that causes it to compare every value. Here is a visulization of what i want

file.a 2,3,4,5
3 5


i want the values 2, 3, 4, 5 from file.a to be compared inbetween values 3 5, 6 9,1 2, 4 7 from file.b (var1 is the value im comparing, var2 is the less value, var 3 is the greater value)

for i in $var1
for k in $var2


my problem with the above code is it compares EVERYINNG, not the values inbetween what i want (which is 3 5, 6 9 etc).

Ubuntu :: Create Two Lists Of File Names Irrespective Of Directories And Compare?

Aug 13, 2010

I have an internal hard drive and an external hard drive, both with about 350 GB of data. The data came from the same source, but over the last couple of years, different people have moved files around to different directories, and some files have been deleted. Now I want to merge all the files onto the internal hard drive. I estimate that 80% of the files on the external hard drive are the same, so I don't want to copy 290+ GB of data over when I already have it.

Therefore, I need a way to find just the files on the external hard drive that don't already exist on the internal one. In other words, I need to create two lists of file names irrespective of directories and compare them, selecting only the file names that exist in one list OR the other. I've Googled for solutions but can't find anything suitable. There are ways to create text files of the file names and compare them with diff, but they have to be in the same order, and since these files are in vastly different directories, that won't work.

General :: Running DF Command - Huge Space Between Columns

Jul 13, 2011

I am running the command on a Mac but due to it being a generic unix command and a command line query.. I thought I can write on this forum.. I am running the command

df -h | grep '/dev/'
I get
/dev/disk0s2 389Gi 62Gi 327Gi 16% /
/dev/disk0s3 76Gi 24Gi 52Gi 32% /Volumes/Backup
/dev/disk3s2 500Gi 47Gi 453Gi 10% /Volumes/Misc
Note the huge space between the 1st and 2nd Column..

This is because currently I have some NAS drives mounted which are not showing due to grep. When they are not mounted. The output is fine with equal spaces between each column (like between col 2 and 3.. or 3 and 4). I want to do a (dare I say) sed or awk or something to reduce the space between 1st and 2nd col. So that it has space like between col 3 and 4.. or 2 and 3. This is because I am showing this output somewhere and because of the space its not showing up correctly.Also I hope the command will still work when the NAS drives (afp) are not mounted.. basically consistency. The spaces are not showing properly in the quote tag. Changed it to CODE tag.
