可否解释一下mv -f !* ~/.trash里!号的意义
你man一下alias有下面一段话:
alias [-p] [name[=value] ...]
Alias with no arguments or with the -p option prints the list of
aliases in the form alias name=value on standard output. When
arguments are supplied, an alias is defined for each name whose
value is given. A trailing space in value causes the next word
to be checked for alias substitution when the alias is expanded.
For each name in the argument list for which no value is sup-
plied, the name and value of the alias is printed. Alias
returns true unless a name is given for which no alias has been
defined.
可见,alias是要=的 |
