Duplicate Line Filter#

Options#

• -c: Count occurrences of each line
• -d: Only show duplicate lines
• -u: Only show unique (non-duplicate) lines
• -i: Case-insensitive comparison

Examples#

bash

# Remove adjacent duplicates
uniq-tool sorted.txt

# Count occurrences

# Only show duplicates
uniq-tool -d sorted.txt
