I need to compare two binary files and get output in form
for every different byte. So if file1.bin is code...
what is the easiest way to accomplish the goal? Standard tool? Some 3rd party tool?
diff has the ability to trasverse directory structures. cmp has the ability to manage binary files.
I'm looking for something which allows me to compare a directory's contents, including files and subdirectories, and so a binary comparison.
Any suggestions, scripts, etc. which may be of help?
Some of my directories are huge, with huge (image) files in them.
1.What character instructd the shell to interpret a special character as an ordinary character?
2.What directory contains some of the utilities available on the system in the form of binary files?
3. What command is used to search the location of a utility?
4. What command is used to instruct the editor to write the file and quit the editor?
5. What key quits the more utility and displays the shell prompt?..........
Is there any Linux utility to combine two or more binary files into a single binary file ?

I want to compare two files in perl, I have two files file1.txt & file2.txt. if column1 on file2.txt match column1 on file1.txt then I want my result on file3.txt (column1 column2 file1.txt + column1 column2 column3 file2.txt). this problem was solved with "awk" but I want to do in perl.

Knowing that Mac is built on Unix makes me wonder if it's the sweet spot between them. But I wonder: how similar is the Mac command line to Linux's bash? Could I pick right up with using vim and bash scripting and git, etc? Would common commands like changing directories be different? Does anybody know an online "compare and contrast" resource?

View 1 Replies View RelatedWhat is the best and simplest way to compare two directory structures without actually comparing the data in files. This works fine:
diff -qr dir1 dir2
But it's really slow because it's comparing files too. Is there a switch for diff or another simple cli tool to do this?
what command is to be used to call strings from other files to the script and then comparing strings from two different files in the script to check if strings are matched then return the result to another script.
View 1 Replies View RelatedI have some data ( seperated by semicolon ) with close to 240 rows in a text file temp1. temp2.txt stores 204 rows of data ( seperated by semicolon ). I want to : Sort the data in both files by field1.i.e first data field in every row. compare the data in both files and print out the rows that are not equal in seperate files. I was trying to do this with excel using vlookup, without a great deal of success. hence, i'm exploring the shell script option.
Code:

View 10 Replies View RelatedI am using the diff command with the -r option, to compare a large number of files and files in subdirectories. My main interest is to find out which files have been changed, and not what the actual changes are, and since a lot of files has been changed, it would be a lot easier to view the file names only. Is there and option for diff that might do this, or does there exist a similar tool/command that could do the job?
View 1 Replies View RelatedToday encoders are getting smarter. They can compress Blu ray similar quality in 700MB. It seems header of video file contain info about frame rate, audio/video encoder etc. which can't be guessed. In MPEG audio , every part of file is independently playable.

Fedora provides several compression techniques. E.g tar, tar.gz, zip etc. I want to know which among them provides
1. the best compression ratio for text files
2. the best compression ratio for binary files
3. fastest compression
I have two files (not sorted) and need to compare line by line (i.e. first line of file1 to be compared to all the lines of file2 and so as for the rest of file1). Output will be an array of length of file2. Any suggestion in BASH other than a grep inside two read line loops ( which is time consuming for files ~1000s of lines).

View 2 Replies View RelatedI have to write a script that accepts two directory names (JIIT, JUIT) as positional parameters and checks which files are identical in both directories and files having same contents are also considered as identical in same directory. I tried using diff:

echo "Enter the directories:"
read d1
read d2
cd $d1
if diff file1.sh file2.sh > /dev/null
