在Linux中,你可以使用Python来获取文件的大小,以下是几种方法:
方法一:使用`os.path.getsize`
```python
import os
def get_file_size(file_path):
return os.path.getsize(file_path)
file_path = '/path/to/your/file'
print(f"The size of the file is: {get_file_size(file_path)} bytes")
方法二:使用`ls`命令
```python
import subprocess
def get_file_size_using_ls(file_path):
result = subprocess.run(['ls', '-l', file_path], capture_output=True, text=True)
size_line = result.stdout.split('\n')
size = int(size_line.split()) 5th column is the size
return size
file_path = '/path/to/your/file'
print(f"The size of the file is: {get_file_size_using_ls(file_path)} bytes")
方法三:使用`du`命令
```python
import subprocess
def get_file_size_using_du(file_path):
result = subprocess.run(['du', '-b', file_path], capture_output=True, text=True)
size = int(result.stdout.split('\t')) The first tab-separated value is the size in bytes
return size
file_path = '/path/to/your/file'
print(f"The size of the file is: {get_file_size_using_du(file_path)} bytes")
方法四:将大小转换为人类可读形式
```python
def human_readable_size(size, decimal_places=2):
for unit in ['B', 'KB', 'MB', 'GB', 'TB']:
if size < 1024.0:
break
size /= 1024.0
return f"{size:.{decimal_places}f} {unit}"
file_path = '/path/to/your/file'
file_size = os.path.getsize(file_path)
print(f"The size of the file is: {human_readable_size(file_size)}")
以上方法可以帮助你在Linux环境中使用Python获取文件的大小。请选择适合你需求的方法进行尝试
