In tcsh/zsh if you do not type anything first, it is like up/down arrows. If you type something first, the list is filtered by "begins with" given what you have typed thus-far. > Yeah, one of the best tcsh(1) features! > Better in bash which allows you to filter not only on "begins with" but also "contains" (which is arguably more valuable than "begins with"). >> To emulate this behaviour in bash, I simply create a .inputrc file in my >> $HOME with the following contents: >> >> # .inputrc field >> "\ep": history-search-backward >> "\en": history-search-forward > > On GNU/Linux boxes mine has: > > "\e[A": history-search-backward > "\e[B": history-search-forward > Interesting that you mapped these to cursor-up/cursor-down. That may cause unexpected results. For example, typing something and then pressing up-arrow will cause the shell to give you the previous command that started with that rather than the previous command in-general. It would then be the case that you cannot navigate the history sequentially unless the input line is empty before using cursor-up/cursor-down. -- Devin
