我有一个包含许多日志文件^H和^M字符，如产生这个文件更新了基于文本的进度栏的过程。
使用时cat，输出会被评估并显示为人类可读和简洁。下面是一个示例输出。
Epoch 11/120
4355/4355 [==============================] - ETA: 0s - loss: 0.0096
Epoch 00011: val_loss did not improve from 0.00992
4355/4355 [==============================] - 1220s 280ms/step - loss: 0.0096 - val_loss: 0.0100
但是，与上面的实际打印文本cat所建议的（70MB 大约 900 行）文本相比，文件本身是巨大的。
下面是日志文件中包含的实际文本的片段。

基本上，我想创建一个看起来就像生成的文件cat。
以下是我尝试过但效果有限的一些方法：
tr -d '\b\r' < logfile > new_file 删除所有字符，但因此留下所有不需要的文本。cat logfile > new_file 实际上只是逐字复制文件而不评估特殊字符。cat logfile | col -b > new_file 非常接近，但在重复行之一上做了一些奇怪的事情：4355/4355 [==============================] - ETA: 0ss--loss::0.0096557
Epoch 00011: val_loss did not improve from 0.00992
4355/4355 [==============================] - 1220s 280ms/step - loss: 0.0096 - val_loss: 0.0100
任何帮助，将不胜感激。
谢谢
