         government [syn: {White House}, {EXEC}]

 /eg.zek'/, /eks'ek/, n.

   1. [Unix: from execute] Synonym for {chain}, derives from the exec(2)
   call.

   2. [from executive] obs. The command interpreter for an {OS} (see
   {shell}); term esp. used around mainframes, and prob.: derived from
   UNIVAC's archaic EXEC 2 and EXEC 8 operating systems.

   3. At IBM and VM/CMS shops, the equivalent of a shell command file
   (among VM/CMS users).

   The mainstream `exec' as an abbreviation for (human) executive is not
   used. To a hacker, an `exec' is always a program, never a person.
