tcsh: can you save the history from multiple shells to one history file?
I often have several terminal windows open at any one time. My history file seems to only hold the history from the last shell I close at the end of the day.
I know I can have each shell write to a different file, but is there a way to have each shell write to the same file so that when I come in the next day & hit the up arrow in a terminal, it will go through everything I did the day before?
I figured something out late last night & didn't bother writing it down. Now what I did is no longer in my history because I closed that terminal down before another one. Trying to avoid that happening again.
