Linux下查看当前目录下文件的个数
ls -l | grep "^-" | wc -l
查看当前目录下文件的个数，包括子目录里的。
ls -lR| grep "^-" | wc -l
查看某目录下文件夹（目录）的个数，包括子目录里的。
ls -lR| grep "^d" | wc -l
简要说明：
ls -l
长列表输出该目录下文件信息(注意这里的文件，不同于一般的文件，可能是目录、链接、设备文件等)
grep "^-"
这里将长列表输出信息过滤一部分，只保留一般文件，如果只保留目录就是 ^d
wc -l
统计输出信息的行数，因为已经过滤得只剩一般文件了，所以统计结果就是一般文件信息的行数，又由于一行信息对应一个文件，所以也就是文件的个数。
