Monitoring Linux File Copy Progress（linux复制进度）
When transferring files between computers on a Linux system, it’s important to be able to monitor their progress. Fortunately, this can be done easily by using the “watch” command. The “watch” command allows you to monitor the progress of files being transferred across the network, giving you a better understanding of what’s going on.
To use the “watch” command to monitor the progress of file copying, enter the command in the terminal. The “watch” command is usually used to continually execute a command, such as “ls” to view the contents of a directory. To watch the progress of file copy, specify the source file and the destination file you are copying it to. This will display a continuous list of the files being copied and how far along the process is:
$ watch -d ‘cp /path/to/source_file /path/to/destination_file’
The “watch” command has a few optional arguments you can use to customize the display. By adding “-d” to the command, you can enable “delta mode” which will provide detailed information about the progress of the copy process. For example, it will show the rate at which bytes are being transferred and the amount of time remaining until the transfer is complete. It will also show the percentage of completion:
$ watch -d ‘cp /path/to/source_file /path/to/destination_file’
Using these options, you can easily monitor the progress of file copy on a Linux system. This can be useful for various tasks such as backups, updates, and migrations. It can also help identify any bottlenecks that may be decreasing the performance of your system.
In addition to using the “watch” command, there are several other tools that can be used to monitor file copy progress on a Linux system. The “rsync” command is one of the more popular ones and it provides a very detailed output that can be customized. For example, you can set the “–progress”argument to show the overall progress of the transfer, including the amount of time remaining:
$ rsync –progress /path/to/source_file /path/to/destination_file
Other popular tools for monitoring file copy progress include the “curl” command, “cp “command, and “scp” command. They all provide detailed output and can be used to monitor the progress of file copy on a Linux system.
Overall, the “watch” command is one of the simplest tools for monitoring file copy progress on a Linux system. It provides you with a constantly updated report on the progress and allows you to quickly identify any issues that might arise. Other tools such as “rsync”, “curl”, “cp”, and “scp” can also be used to provide a similar level of monitoring. With these tools, you have a wide range of options for staying informed about your file copying progress on your Linux system.
