什么是/ bin/sh -c？

Question

什么/bin/sh -c意思？怎么-c办？

Answer 1

从bash的手册页:

-c string If  the  -c  option  is  present, then commands are read from
          string.  If there are arguments after the  string,  they  are
          assigned to the positional parameters, starting with $0.

例:

$ bash -c ls

将启动bash并执行命令ls.

/bin/sh 通常是shell的符号链接.
