General :: Comparing Lines In 2 Text Files?
Nov 5, 2010Is 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?

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.
Example:
file size
motherfile.txt 5000 lines.
after split
motherfile.txt 2000 lines.
childfile1.txt 2000 lines.
childfile2.txt 1000 lines.
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.

View 1 Replies View RelatedI 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?
I have a file1:
Code:
$ cat PF(1).out
Tmp39 PF10271.3 423 ENSP00000326063 488 1.2e-201 41-478

I wish to compare all the files in a directory....comparing is by content. And same files should be printed...
echo "program : $0"
cd $1
for a in *
do
[code]....
This logic did not give the correct result...
I want to compare two files and display values unique to file1. I tried using comm but it did not give me useful outputs.
comm -2 -3 file1 file2 does not work
Similar threads provide matched content. What I am looking for is unique content.
Iam having the following two linux files.
[Code]...
Now i want the following out puts
1. similar nos in both the file 1 and file 2 > output= File 3;
2. In file 1, but not in file 2 > out put= file 4;
3. In file 2, but not in file 1 > output = file 5;
The command sdiff is giving output with symbols > < | etc, and the such output file is not clear and ready to print. I want to print directly the output files. AND ALSO TELL ME WHERE I HAVE TO WRITE AWK PROGRAMS AND HOW TO RUN IT.
Two files contain:
file1:
cat
dog
fish
hamster
file2:
cat
fish
ferret
dog
How do you change the case of the letters in file1.txt to uppercase and compare with file2 all in one command?
Im trying to compare two files and I only want to display the user names that are in the first file and not the second.
So I have one file named final.txt (which contains every user name and only the user names in a list no other information)
Then I have another file Over1.txt (which only contains certain users that have different permissions This file is also setup differently with the user name and some information about the user after the user name.
I need a way to compare final.txt to over1.txt so that I will only display the names that are in final.txt but not Over1.txt
Ive tried using diff and comm but just cant seem to get it two work correctly. Im not sure if im missing a option or what.

I have a few rather large text files, and I need a way to look at the first three lines of each. Is there a way to do this using awk?
View 3 Replies View Relatedi 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
I need to insert 3-4 lines of text to the beginning of a text file. The file is a largish MYSQL dump, the result of a backup shell script. This shell script should insert the required text.I've wrestled with sed, but lost.

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.

got the same thing in terms of a u: number but the issue is I need to remove duplicates and just leave one and the file has multiple duplicates of different u: numbers and it's 14,000 lines long. can anyone tell me if I can use awk? sed? or sort for something like this to? removing lines that have a certain string in there that's a duplicate.
Using sed, I am trying to append four commas ',,,,' at the end of lines containing the pattern 'Response' in a text file with lines such as these:

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)
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.
