在Linux环境下编写一个能够同时写入多个文件的程序,通常涉及到多线程或多进程编程,以及文件I/O操作。以下是一个使用Python编写的简单示例,该程序将创建多个文件,并向每个文件写入一些内容。
以下是一个使用Python多线程同时写入多个文件的示例:
import threading
def write_to_file(filename, content):
with open(filename, 'w') as file:
file.write(content)
print(f"Written to {filename}")
# 文件名列表和对应的内容
files = {
'file1.txt': 'This is the content for file 1.',
'file2.txt': 'This is the content for file 2.',
'file3.txt': 'This is the content for file 3.'
}
# 创建并启动线程
threads = []
for filename, content in files.items():
thread = threading.Thread(target=write_to_file, args=(filename, content))
threads.append(thread)
thread.start()
# 等待所有线程完成
for thread in threads:
thread.join()
print("All files have been written.")
以下是添加了文件锁和异常处理的改进版本:
import threading
def write_to_file(filename, content, lock):
try:
with lock:
with open(filename, 'w') as file:
file.write(content)
print(f"Written to {filename}")
except IOError as e:
print(f"Error writing to {filename}: {e}")
# 文件名列表和对应的内容
files = {
'file1.txt': 'This is the content for file 1.',
'file2.txt': 'This is the content for file 2.',
'file3.txt': 'This is the content for file 3.'
}
lock = threading.Lock()
threads = []
for filename, content in files.items():
thread = threading.Thread(target=write_to_file, args=(filename, content, lock))
threads.append(thread)
thread.start()
for thread in threads:
thread.join()
print("All files have been written.")
通过这种方式,可以确保在多线程环境下安全地写入多个文件。
