General :: Comparing Lines In 2 Text Files?

Nov 5, 2010

Is there a way, besides writing a PERL program, to read each line one by one in file A and tell if this line also exists in file B? Can this be done via a shell script?

General :: Splitting Text Files Into Parts With 2000 Lines

Sep 7, 2010

I am facing a problem while splitting a text file, I need to split a file into some parts and each split file should have 2000 lines, when I do it through "split" command the mother file is kept intact but as per my requirement I need to cut mother file into some parts thus it should not be kept intact.

after split
motherfile.txt 2000 lines.
childfile1.txt 2000 lines.
childfile2.txt 1000 lines.

Software :: Compare/diff A Range Of Lines From Two Text Files?

Mar 26, 2010

i tried using diff --GTYPE-group-format= with <%, but not sure that right solution.Here's what im trying to do. I have two c source files, file1 and file2. file1 has a function in it that's been modified in file2. However, the functions begin at differnt line numbers in eachof the files. Is there a way to specify a range of file numbers on file1 and file2 to compare, using diff or any other combination of utilities? I can always output text from a range of lines from each file to two separate and new files and then compare those, but that's tedious. I could also write up a script to automate this type of solution, but I imagine there's an existing way of doing this.

General :: Comparing Multiple Of Files ?

Mar 20, 2010

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?

Programming :: Bash Text To Variable Accessing Individual Text Lines?

May 2, 2010

i am on processing text tasks And i found that if you assign a text to a variable is chomp'ed automatically the newline

Code:

variable=$(cat file.txt)

The problem is i can only access the items/lines using:

Code:

for line in $variable
do
echo $line
# Other commands
done

how do i convert this to an indexed array. More importantly, how do i get access to individual $line[0], ..., $line[n] Another thing, if the file.txt, has lines with spaces it is a mess using the for...in..., but echoing prints line by line...o_0

General :: Sed - Replacing Only Text With Several Specific Lines Excluded

Jun 17, 2010

As much as I didn't want to ask a sed question, especially considering there's already one on this page I've looked as best I could and cant find the solution. Id like to use sed to replace occurrences of a pattern but exclude two or 3 specific lines that are not consecutive. For example I know with 1,10 i could exclude the first 10 lines, what is the syntax if I just wanted to exclude line 3 and 7. The sed command I'm working with right now is for rearranging Ethernets.

cat /etc/udev/rules.d/70-persistent-net.rules | sed -e '/'"$found1fullmac"'/!s/eth1/'"found1eth"'/' > /etc/udev/rules.d/70-persistent-net.rules

I would like to replace $found1fullmac with two variables representing line numbers to exclude from the replacement.

Programming :: Comparing Two Files ?

May 7, 2011

I have two files

Code:

we have to consider here $5 , $6 , $7 for our search

file2.txt

Code:

Here we should take only $2 for comparison. As you can most of the $2 field records has value and some do not have value.

Question:I want to take the fields $5 , $6 , $7 from file 1 and compare it with $2 field from file 2. and the rsult should be like this:

Code:

The final output will look like this

Actual file1.txt (before running the code)

Code:

FIle1.txt after running the above said condition

Code:

So the field $5 , $6 , $7 should get replaced from the matched valued of $1(file1)

General :: Loop Append Text To Text Files?

Jan 15, 2010

may be an advanced question but I need to know how to do this. Here at work I am in charge of recruiting and we have about 1,000 resumes in already. All of the resumes are in a .pdf format. I need to rename every .pdf in the following format:{firstnameLastname}.pdfThe only way I know how to do this is to convert all the .pdf files to text, extract the name out of the first few lines of text, import into excel, and then use VBA to rename the files in mass:Here is my logic so far:~Deskop/a = houses all the .pdfresumesOpen terminal: Code: cd ~/Desktop/afor f in *.pdf; do pdftotext -raw $f; done That will convert all of the preceding resumes into text filesNow I would like to append the name of the text file into the last line of the text file. So, for example, for Resume1.txt, I want to append "Resume1.txt" to the last line within Resume1.txt. So after I run the command I open Resume1.txt and on the last line within I want to see "Resume1.txt" on the last line, at the end of the resume.How can I do this? I would like to use a loop and have the terminal append the filename to the body of the text file until all of the have been appended.
