The fundamental principle is that it prints out all of. The tree can be used for quick comparison by number of folders and files of various paths by printing last row of the output: tree /path/to/dir1 tail -n 1 tree /path/to/dir2 tail -n 1 will prints 0 directories, 5 files 0 directories, 3 files BUT keep on mind that it is just a number of folders or files so there. I have to create a bash script that compares content by file names in two directories, for example 'FirstDirectory' contains file with name '123456' therefore 'SecondDirectory' should also contain 'file123456.png'. I was only able to test this on CentOS 6.4, but AFAIK it should work the same in Ubuntu 12.04.ĮDIT: I should note that smithian's answer is undoubtedly better, but I wanted to take a stab at doing it with your original rsync command in tact since it was giving you the desired output. The following (if you substitute the first directory for directory1 and the second for directory2) should do what you're looking for and swiftly: find directory1 -type d -printf 'P ' sort > file1 find directory2 -type d -printf 'P ' sort diff - file1. Check the manual of rsync or try the option -help to get more options and examples on how to use it. ![]() To change any of these options and for more details about. You can use the same command to make both directories equivalent (timestamp, permissions, etc.). By default, the compare includes all files in the folders, and is recursive (does include subfolders). In other words, it avoids creating folder3/folder1/. It will tell you which files are different. This is the slower option, but I believe it meets your requirements, and it could be executed using non-relative directory names: rsync -rcnC -out-format="%n" folder1/ folder2/ |grep -vP "/$" |xargs -I, ignoring folder1/. That's the simplest form I could come up with, if you're willing to first descend into folder1 before issuing the command. It is easier to use, especially for desktop users. Meld: A GUI tool that you can install to compare files and directories. Then to create links to files between the directories use ln -s dir1/File1 dir2/.Rsync -rcnC -out-format="%f". There are two main tools that you can use for comparing files in Linux: diff: A command line utility that comes preinstalled on most Linux systems. $0 # This causes the script to call itself. For me the final solution was in two steps, first call rsync with full path, then a find command to remove all empty directories: rsync -rvcm -compare-dest/tmp/org/ /tmp/new/ /tmp/difference/ find /tmp/difference/ -d -type d -empty -exec rmdir. program to compare two directories Check for required arguments if -ne 2 then echo 'usage: 0 directory1 directory2' 1>&2 exit 1 fi Make sure both arguments are directories if -d 1 then echo '1 is. The rsync way given by Thane with Yamaneko additions work great but leave empty directories. I want to know if one directory contains the same file as the other. # if "filename" is a directory but not a softlink I have two directories, they contain common files. ![]() The du command returns the disk usage, and its option -apparent-size doesnt solve the problem. # for all files and directories in the current directory. How to compare the size of two directories I want to compare the total size of two directories dir1 and dir2 on different file-systems so that if diff -r dir1 dir2 returns 0 then the total sizes will be equal. Diff is normally used to compare two files, but can do much more than that. Here is an example script I wrote a long time ago to rename all files with spaces in the filename to use a underscore instead of a space. To walk the directory tree you need to use recursion. Example output (depends on locale): ls dir1 dir2 dir1: same-file different only-1 dir2: same-file different only-2 diff -qr. r When comparing directories, recursively compare any subdirectories found. ![]() Visualize global and local differences with insertions, changes and conflicts marked accordingly. From the diff man page: -q Report only whether the files differ, not the details of the differences. Navigate between differences and conflicts. Edit files in-place and the difference comparison updates immediately. The command you are looking for to do the comparisons is md5sum or diff.įor example here is a script that just compares the md5sums of two files specified on the command line: #!/bin/bash The open source Meld tools has the following main features: Perform two and three-way difference comparison. You should be able to do this trivially in bash.
