Compress (zip) and decompress (unzip) commands in Centos

When using ftp to back up data, it takes a lot of time because there are too many files, so we need to use the compression and decompression commands, for example, I need to back up the/opt/data folder, however, since there are tens of thousands of files in data, you need to use the zip command. For details, see data File compression before transmission:

Cd/opt

Zip-r data.zip data

OK ,compress the datafile into the data.zip format, which is very fast for uploading and downloading. In the same way, when you upload the compressed file to centos, you can use unzip to decompress the file. For example, run the following command to decompress/opt/data.zip:

Cd/opt

Unzip data.zip

# Unzip-t large.zip

6. I used -v8.0 to find that there are many directories and subdirectories in the music.zip compressed file, and the subdirectories are actually mp3 files. I want to download these files to the first-level directory instead of the first-level directory:
