csh 20110502-7 (armhf binary) in ubuntu jammy

 The C shell was originally written at UCB to overcome limitations in the
 Bourne shell. Its flexibility and comfort (at that time) quickly made it
 the shell of choice until more advanced shells like ksh, bash, zsh or
 tcsh appeared. Most of the latter incorporate features original to csh.
 .
 This package is based on current OpenBSD sources.
