DeDup is a Java command-line utilty for removing duplicate lines in text files. The dedup process compares adjacent lines only. It does not sort first. The comparison is case sensitive. It removes adjacent indentical lines. It replaces the original file, so do a backup first. You can dedup 1 to N files in one execution, just put their names on the command line. DeDup deletes blank lines from both the beginning and end of the file. It as well deletes trailing blanks from each line. It also cleans up line terminators and converts them all to platform standard. If the file is already deduped, it does not change the date. Use it with: java com.mindprod.dedup.DeDup myfile.txt anotherfile.txt yetanotherfile.txt or java -jar dedup.jar myfile.txt anotherfile.txt yetanotherfile.txt or, if you have the jar association set up, even even dedup.jar myfile.txt anotherfile.txt yetanotherfile.txt It can handle a list of files, or an os-expanded wildcard. It does not -s to process subdirectories or the use of directory names to process entire directories.
