I have created two completion: _nkf and _lha. Both nkf(1) and lha(1) are very old unix commands and still used in Japan. nkf(1): http://sourceforge.jp/projects/nkf/ nkf is a Kanji code converter filter. It converts input kanji code to another kanji code. lha(1): http://sourceforge.jp/projects/lha/ lha is an archiving/compression utility for LZH format archives. LZH format is legacy and no longer used. But lha(1) command is still rarely used for decompress old LZH files. Would you capture these completions? BR, cat_in_136
