Operation Details
Remove Duplicate Lines
The first occurrence of each duplicate line will remain in the file. The Sorted option will sort the file and remove duplicate lines [fast on large files]. The Ordered option will keep the same order of lines [slow on large files].
Example: Suppose a file has the following lines. (#comments added for clarity)
Line 2 Line 1 Line 2 #removed Line 3 Line 1 #removed Line 2 #removedThe Remove Duplicate Lines, sorted will change the file into this:
Line 1 Line 2 Line 3The Remove Duplicate Lines, ordered will change the file into this:
Line 2 Line 1 Line 3
Remove Unique Lines
Removes all lines that appear only once.
Example: Suppose a file has the following lines. (#comments added for clarity)
Line 2 Line 1 Line 2 Line 3 #removed Line 1 Line 2The Remove Unique Lines will change the file into this:
Line 2 Line 1 Line 2 Line 1 Line 2
Remove Empty Lines
Removes all lines that only contain a newline character, and no other characters.
Example: Suppose a file has the following lines. (#comments, and \n newline characters added for clarity)
Line 2\n Line 1\n \n #removed \n #NOT removed (contains spaces) Line 1\n Line 2\nThe Remove Empty Lines will change the file into this:
Line 2\n Line 1\n \n Line 1\n Line 2\n
Remove Whitespace Lines
Removes all lines that have only whitespace characters.
Example: Suppose a file has the following lines. (#comments, and \n newline characters added for clarity)
Line 2\n Line 1\n \n #removed \n #removed (contains only whitespace chars) \t \n #removed (contains only whitespace chars) Line 1\n #NOT removed (contains non whitespace chars) Line 2\nThe Remove Whitespace Lines will change the file into this:
Line 2\n Line 1\n Line 1\n Line 2\n

Sorts lines ascending or descending based on ASCII values (lexicographic sort).
Example: Suppose a file has the following lines.
line 1 line 2 line line 3 lineThe Sort Lines Ascending will change the file into this:
