unlike

Command line tool to point differences between two folders.

unlike will compare both folders and give a detailed description of what is different from one folder to the other. unlike is safe to use; it will not change the contents of any folder.

Installation

npm install --global unlike

It should work fine in Linux and OSX. I don't expect it to work in Windows because I haven't tested yet. Let me know if it does.

How to use

unlike [options] <source_dir> <dest_dir>

Available options:

• -s, --size: compare file sizes
• -a, --atime: compare file access times
• -m, --mtime: compare file modified times
• -c, --ctime: compare file change times
• -v, --verbose: toggle verbose mode

If no option is passed, unlike treats files as equal sufficing that their names are equal, even if their sizes differ.

Beware option -c does not compare file creation times, but file change times! See what Google has to say about it.

Example

Assuming the following folder structure:

f1/
    a   // file contains string "123\n"
    b   // file contains string "456\n"
f2/
    a   // file contains string "123\n"
    b   // file is empty
    d

Issuing the command below will produce the following output:

To do

Add the following checks:

• files having different contents (maybe using checksum)
• files with different access modes
