如何将 bash 中的特定输入映射到命令？
How do I map a certain input in bash to a command?
所以我想知道是否可以将某个输入映射到 gnome 终端中的命令。例如，当我在命令shell中输入"foo"时，它会自动执行某个命令，比如进入一个程序所在的目录，并以特定的配置执行该程序。
是的，它被称为 alias:
A Bash alias is essentially nothing more than a keyboard shortcut, an
abbreviation, a means of avoiding typing a long command sequence. If,
for example, we include alias lm="ls -l | more" in the ~/.bashrc file,
then each lm [1] typed at the command-line will automatically be
replaced by a ls -l | more. This can save a great deal of typing at
the command-line and avoid having to remember complex combinations of
commands and options. Setting alias rm="rm -i" (interactive mode
delete) may save a good deal of grief, since it can prevent
inadvertently deleting important files.
所以基本上：
alias foo="cd /path/to/dir; ./myprogram; cd -"
cd - 遵循@Cyrus 的建议 - return 将您转到您开始的目录。这对大多数命令来说更安全，更令人期待，但是当然，您可以使用任何您喜欢的方式。
