linux compress and decompress files

The commonly used compressed file on Linux is the tar.gz file, which is tgz, and the command corresponding to these files is tar. But there are also some files that we uploaded from the Windows computer, such as zip files, the command corresponding to these files is unzip. A summary is given below.

1 、 tar

tar has the following parameters:

• -c : create parameters for creating compressed archives;
• -x : Parameters for decompressing compressed archives;
• -z : Whether to compress with gzip;
• -v: Display files during compression;
• -f: put the file name at the top, followed by the file name immediately after f, no parameters can be added

For example, package the /home/fengchi863/deeplearning/imageCaptcha/nets folder (only package, not compress):

tar -cvf /home/fengchi863/deeplearning/imageCaptcha/nets.tar /home/fengchi863/deeplearning/imageCaptcha/nets

After packaging, perform gzip compression:

tar -zcvf /home/fengchi863/deeplearning/imageCaptcha/nets.tar.gz /home/fengchi863/deeplearning/imageCaptcha/nets

The compressed file name after the parameter f is taken by yourself. It is customary to use tar to do it. If the z parameter is added, tar.gz or tgz will be used to represent the gzip compressed tar file.

Extract the tgz file to the specified directory

tar zxvf nets.tgz -C 指定目录

For example, unzip the nets.tgz file to the directory under the user name

tar zxvf nets.tgz -C /home/fengchi863

2、unzip

Files transferred to linux via ssh are sometimes zip compressed files on Windwos. Then use zip to unzip it.

unzip 指定文件 -d 目标文件夹

For example, unzip the nets.zip file to the current directory

unzip nets.zip
