Sounds as if you are experiencing a limit with the operating system
that cannot be changed. .... How many files were you expecting back from the ls listing .... a large number I suspect ?

The file /usr/include/sys/param.h defines
the variable NCARGS, which in turn defines the size for the argument
list. There is no way to change this value.... although the comments in
this file seem to indicate it is changeable, remember that all of the
Operating System has already been compiled based on the header file in
its current state.

You can try to break your "ls" command into smaller pieces, or use other code method.

试试ls det/*200702*|xargs wc -w或find det -name *200702* -exec wc-w {} \;
也许可以解决你的问题，具体的解释请查看man

注意:第二个命令结尾要加";"哦

使用通配符后，多数 shell 会将它自动转换成一长串参数列表。如果目录下面的文件匹配通配符的结果颇多，就可能导致产生这样的错误。不妨用 find 试试。
