find:paths must precede expression问题及解决

用find命令查找时

例如命令

find /home -name w*

如下

find: paths must precede expression: webfd
Usage: find [-H] [-L] [-P] [-Olevel] [-D help|tree|search|stat|rates|opt|exec] [path...] [expression]

会出错，查文档找出

find: paths must precede expression

Usage: find [-H] [-L] [-P] [-Olevel] [-D help|tree|search|stat|rates|opt|exec]

[path…] [expression]

This happens because *.c has been expanded by the shell resulting in find

actually receiving a command line like this:

find . -name bigram.c code.c frcode.c locate.c -print

That command is of course not going to work. Instead of doingthings

this way, you should enclose the pattern in quotes or escape the wildcard:

$ find . -name '*.c' -print
或
$ find . -name \*.c -print

即出现这个提示是因为星号代表为当前目录下所有的文件，然后被当做shell展开
这就是网上说的多文件的查找的时候需要增加单引号
