Display all acronyms
The “wtf” utility uses this acronyms database (gzipped for download), from NetBSD® but extended by many contributors including “wtfubar”, to expand acronyms and abbreviations for you. As of database CVS revision 1.793 (2021-04-11T16:30:31Z) (6.76 MiB uncompressed), 136757 expansions for 106446 unique acronyms are known.
The wtf(1) utility is core to MirBSD. It is also available from my APT repository (for use with Debian®-based operating systems), as offline utility.
There are offline-capable Äpps for multiple operating systems as well: for Android, Jolla/SailfishOS and Blackberry Z10 users there’s a Free Äpp in F-Droid, by Natureshadow (source repo). An iOS äpp for iPhone users by Eugen¹ also exists. These download on first use the acronyms database and use it offline; the iOS äpp checks (and downloads) updates automatically while the Android äpp offers this in the menu (traffic-friendlier).
For the regular MirBSD online documentation (manpages, HTML and papers), we also offer a manual page search CGI.
