Linux查看文件大小的几种方法

stat命令

    xanarry@ThinkPad:/$ stat ~/Downloads/jdk-8u60-linux-x64.tar.gz
    File: '/home/xanarry/Downloads/jdk-8u60-linux-x64.tar.gz'
     Size: 181238643       Blocks: 353984     IO Block: 4096   regular file

wc命令

    wc -c filename 参数-c表示统计字符, 因为一个字符一个字节, 所以这样得到字节数

    xanarry@ThinkPad:/$ wc -c  ~/Downloads/jdk-8u60-linux-x64.tar.gz
    181238643 /home/xanarry/Downloads/jdk-8u60-linux-x64.tar.gz

du命令

    du -b filepath 参数-b表示以字节计数

    xanarry@ThinkPad:/$ du -b  ~/Downloads/jdk-8u60-linux-x64.tar.gz
    181238643       /home/xanarry/Downloads/jdk-8u60-linux-x64.tar.gz


或者

    du -h filepath 直接得出人好识别的文件大小

    xanarry@ThinkPad:/$ du -h  ~/Downloads/jdk-8u60-linux-x64.tar.gz
    173M    /home/xanarry/Downloads/jdk-8u60-linux-x64.tar.gz


ls命令

    ls -l filepath 第五列为文件字节数

    xanarry@ThinkPad:/$ ls -l  ~/Downloads/jdk-8u60-linux-x64.tar.gz
    rw-rw-rw- 1 xanarry xanarry 181238643 10月  2  2015 /home/xanarry/Downloads/jdk-8u60-linux-x64.tar.gz


    ls -h filepath h表示human, 加-h参数得到人好读的文件大小

    xanarry@ThinkPad:/$ ls -lh  ~/Downloads/jdk-8u60-linux-x64.tar.gz
    rw-rw-rw- 1 xanarry xanarry 173M 10月  2  2015 /home/xanarry/Downloads/jdk-8u60-linux-x64.tar.gz
