/Shell/Bash/Bash return unique lines starting at nth field

Bash return unique lines starting at nth field

# Basic syntax:
uniq -f number input_file
# Where number specifies the number of fields/columns to ignore from left 
#	to right when doing comparisons to return unique lines

# Note, uniq requires a sorted input. You can sort a file based on 
#	specific fields with sort -k start_field_#,end_field_#

# Example usage:
sort -k 5,7 input_file | uniq -f 5 # This would sort the file using 
#	fields 5-7 and then return unique lines based on a comparison 
#	starting at the 5th field
