arcv - convert archives to new format
arcv file ...
_A_r_c_v converts archive files (see _a_r(1), _a_r(5)) from 6th edi- tion to 7th edition format. The conversion is done in place, and the command refuses to alter a file not in old archive format.
Old archives are marked with a magic number of 0177555 at the start; new archives have 0177545.
