一段时间后,电话接通
“....这里是西安市110报警中心...”
“西工大至劳动南路路北公交站牌处有小偷,刚偷了我钱包,我追回了”

!
Reverse (or negate) the sense of a test or exit status [bang]. The ! operator inverts the exit status of the command to which it is applied (see Example 6-2). It also inverts the meaning of a test operator. This can, for example, change the sense of equal(=) to not-equal(!=). The ! operator is a Bash keyword..
In a different context, the ! also appears in indirect variable references.
In yet another context,from the command line,the ! invokes the Bash history mechanism. Note that within a script, the history mechanism is disabled.
*
Wild card [asterisk]. The * character serves as a “ wild card” for filename expansion in globbing. By itself, it matches every filename in a given directory.
