Copying a folder is the process of copying all the contents of a folder to another location. The following are some basic command options and parameters:
cp [选项] 源目录 目标目录
Among them, thecpcommand is used to copy files or folders. You need to provide the source and destination directory addresses and specify the locations of the source and destination folders.
For example, if you want to copy all the contents in the/home/lihuanyu/Data/Mini_imagenet/MyImagenetdirectory to/home/lihuanyu/code/06paper1/01model_pretraining/data /directory, you can use the following command:
cp -r /home/lihuanyu/Data/Mini_imagenet/MyImagenet /home/lihuanyu/code/06paper1/01model_pretraining/data/
In this example, the-rparameter means recursively copy the entire directory. You can also change this parameter to control how replication behaves.
Moving a folder is the process of moving a folder from one location to another. The following are some basic command options and parameters:
mv [options] source directory target directory
Among them, themvcommand is used to move files or folder. You need to provide the source and destination directory addresses and specify the locations of the source and destination folders.
For example, if you want to move the/home/user/projectdirectory to the/backup/projectdirectory, you can use the following command:
mv /home/lihuanyu/Data/tiny-imagenet-200 /home/lihuanyu/code/06paper1/01model_pretraining/data/
In this example, themvcommand will move the/home/lihuanyu/Data/tiny-imagenet-200directory to/home/lihuanyu/code/06paper1 /01model_pretraining/data/directory.
Now let’s see how to use the move and copy operations of folders in actual applications.
Suppose you have an important configuration file stored in the/etcdirectory. To back up this file, you can copy the entire directory to the backup directory. The following is an example of copying the/etcdirectory to the backup directory/backup/etc:
cp -r /etc /backup
If you want to move a completed project to another location to free up local disk space, you can use themvcommand to Move folders. The following is an example of moving the/home/user/projectdirectory to the/backupdirectory:
mv /home/user/project /backup
When working with larger folders, you may need to archive data to save disk space. The tar command can package multiple files into a single archive. The following is an example of archiving the/home/user/projectdirectory into the/backup/project.tar.gzfile:
tar -czvf /backup/project.tar.gz /home/user/project
In this example,-cmeans creating a new archive file,-zIndicates using the gzip algorithm to compress files,-vindicates displaying progress information and outputting it to the terminal,-findicates specifying the output archive file name.
