二进制“尾”文件

通过管道将其输送至hexdump:

tail -f somefile | hexdump -C

还有 bintail

这个 双翅目 包包含一个应用程序, 双翅目 . 该程序从磁盘读取一个普通文件,并将输出逐字节传输到标准输出,无需翻译,类似于 尾 (1) 对文本文件不执行任何更改。这对于实时写入二进制文件(如WAV文件)时“跟踪”二进制文件非常有用。这个应用程序正在开发中,但它已经完成了为我设计的功能。

LinuxCoreutilstail(1)在二进制文件上运行良好。对于大多数应用程序,您只需要避免它的行定向,这样输出就不会在数据结构中间的某个随机点开始。您只需从文件开头开始即可,这也是您要求的:

tail -c +1 -f somefile

很好用。

此针对Windows的快速编码Python脚本可能会有所帮助:

# bintail.py -- reads a binary file, writes initial contents to stdout,
# and writes new data to stdout as it is appended to the file.

import time
import sys
import os
import msvcrt
msvcrt.setmode(sys.stdout.fileno(), os.O_BINARY)

# Time to sleep between file polling (seconds)
sleep_int = 1

def main():
    # File is the first argument given to the script (bintail.py file)
    binfile = sys.argv[1]

    # Get the initial size of file
    fsize = os.stat(binfile).st_size

    # Read entire binary file
    h_file = open(binfile, 'rb')
    h_bytes = h_file.read(128)
    while h_bytes:
        sys.stdout.write(h_bytes)
        h_bytes = h_file.read(128)
    h_file.close()


    # Loop forever, checking for new content and writing new content to stdout
    while 1:
        current_fsize = os.stat(binfile).st_size
        if current_fsize > fsize:
            h_file = open(binfile, 'rb')
            h_file.seek(fsize)
            h_bytes = h_file.read(128)
            while h_bytes:
                sys.stdout.write(h_bytes)
                h_bytes = h_file.read(128)
            h_file.close()
            fsize = current_fsize
        time.sleep(sleep_int)

if __name__ == '__main__':
    if len(sys.argv) == 2:
        main()
    else:
        sys.stdout.write("No file specified.")

less somefile

然后按 shift F

严格地说,您需要编写一个程序来实现这一点,正如 tail 未指定用于处理二进制文件。如果您希望尽快接收新的“涓流”数据,可能还需要避免缓冲问题。

我使用它,因为它也适用于实时流:

cat ./some_file_or_dev | hexdump -C

按键(和释放)示例:

[user@localhost input]$ sudo cat /dev/input/event2 | hexdump -C

我使用这个命令(1表示要解释的字节数): 尾部-f |外径-x1
