Find duplicates.. (Alt+Ctrl+X)
Searches the selection for duplicate lines
. Then either counts and/or removes duplicates, or removes unique lines, depending on following options and choices:
- All lines (remove duplicates) - Removes all duplicate
lines
, keeping exactly one instance of each original line. The order of resultinglines
remains unchanged and from each two equal lines, the second one is removed. This is identical to the behavior of the Unique.. tool. - Unique lines only - Removes all
lines
that have duplicates, leaving only thoselines
that were already unique. The order of resultinglines
remains unchanged. - Duplicated lines only - Removes all
lines
that do not have duplicates, leaving only thoselines
that do have duplicates. The resultinglines
are uniqued in the process, thus each resultingline
appears only once in the results. The order of resultinglines
remains unchanged.
Optionally, if the Count duplicates option is checked, the tool counts number of duplicates of each line
and adds these numbers to the results. Each resulting line then contains a number of its duplicates, written in brackets, in front of that line.
Additionally, Leave empty lines option may be specified to spare all empty lines
from being removed, counted or otherwise modified. This can, for example, prevent unwanted paragraph
joining. If this option is not specified, even empty lines get counted and/or removed, which might not be always desired.
And finally, Ignore case option may be specified to ignore case
when matching duplicates.
