One of the most irritating things about working on terminal
based systems was the lack of command line recall. To be fair
though, early unix systems with csh or sh lacked that as well.
Solution here was to select tcsh, which did have command line recall
capability, even back in the early 1990's

Not a problem now, bash, csh and perhaps others. all support command
line recall, with cmdline buffer length a terminal setup parameter.
history (aliased h), shows the whole list, with !<line number>, 
selecting and running any item.

Can be a steep learning curve, and easily forgotten without use,
but so much workflow power in the unix shell...
