删除文件
rm -r *.pdf
但是一次性删除太多的话就会报错 zsh: argument list too long: rm 此时用
find . -name "*.pdf" -print0 | xargs -0 rm

移动文件
mv folder2/*.* folder/ 
移动太多会报错
find folder2 -name '*.*' -exec mv {} folder \;
-exec runs any command, {} inserts the filename found, \; marks the end of the exec command.

查看当前路径下文件个数（不包括下一级子目录里文件个数）
ls -l | grep "^-" | wc -l
查看当前路径下文件个数（包括下一级子目录里文件个数）
ls -lR| grep "^-" | wc -l
查看某目录下文件夹(目录)的个数（包括子目录）
ls -lR | grep "^d" | wc -l

命令解析：
ls -l
长列表输出该目录下文件信息(注意这里的文件是指目录、链接、设备文件等)，每一行对应一个文件或目录，ls -lR是列出所有文件，包括子目录。

grep "^-"
过滤ls的输出信息，只保留一般文件，只保留目录是grep "^d"。

wc -l
统计输出信息的行数，统计结果就是输出信息的行数，一行信息对应一个文件，所以就是文件的个数。
