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 the data file, you need to use the zip command at this time. for details, see data file compression and transfer: cd/optzip-rdata.zipdataok. the data file is compressed into data.zip format. this is the upload and download method.

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

5. I downloaded a compressed file large.zip and want to verify whether the downloaded file is complete.

# 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:
