$ git log --diff-filter=D -- path/to/targetfile.pl
[--] <path>... Show only commits that are enough to explain how the files that match the specified paths came to be. See History Simplification below for details and other simplification modes. Paths may need to be prefixed with -- to separate them from options or the revision range, when confusion arises.
$ git log --help | grep -A20 diff-filter --diff-filter=[(A|C|D|M|R|T|U|X|B)...[*]] Select only files that are Added (A), Copied (C), Deleted (D), Modified (M), Renamed (R), have their type (i.e. regular file, symlink, submodule, ...) changed (T), are Unmerged (U), are Unknown (X), or have had their pairing Broken (B). Any combination of the filter characters (including none) can be used. When * (All-or-none) is added to the combination, all paths are selected if there is any file that matches other criteria in the comparison; if there is no file that matches other criteria, nothing is selected. Also, these upper-case letters can be downcased to exclude. E.g. --diff-filter=ad excludes added and deleted paths. Note that not all diffs can feature all types. For instance, diffs from the index to the working tree can never have Added entries (because the set of paths included in the diff is limited by what is in the index). Similarly, copied and renamed entries cannot appear if detection for those types is disabled.
