Compressing and decompressing tools:

zip: This is one of the most popular tools for creating compressed files in Linux. It packages files and directories into a single archive file with a .zip extension.

Usage:
```
zip archive_name.zip file1 file2 dir1
```
unzip: This tool is used to extract files from a .zip archive.

Usage:
```
unzip archive_name.zip
```

tar: Short for Tape Archive, tar is commonly used to combine multiple files into a single file, known as a tarball, with extensions like .tar. While tar itself does not compress files, it is often used in conjunction with compression tools like gzip or bzip2.

Usage:
```
tar -cvf archive_name.tar file1 file2 dir1
```

gzip: This tool compresses files using the GNU zip algorithm, typically resulting in .gz files.

Usage:
```
gzip file1
```
gunzip: This is used to decompress .gz files.

Usage:
```
gunzip file1.gz
```

Combining tar and gzip:

tar -czvf archive_name.tar.gz file1 file2 dir1
tar -xzvf archive_name.tar.gz

bzip2: This tool provides higher compression ratios than gzip, but it is slower. It results in files with a .bz2 extension.

Usage:
```
bzip2 file1
```
bunzip2: This is used to decompress .bz2 files.

Usage:
```
bunzip2 file1.bz2
```

Combining tar and bzip2:

tar -cjvf archive_name.tar.bz2 file1 file2 dir1
tar -xjvf archive_name.tar.bz2

xz: This tool provides high compression ratios and is used to compress files to .xz format.

Usage:
```
xz file1
```
unxz: This is used to decompress .xz files.

Usage:
```
unxz file1.xz
```

Combining tar and xz:

tar -cJvf archive_name.tar.xz file1 file2 dir1
tar -xJvf archive_name.tar.xz

7z: This is the command-line version of the 7-Zip compression tool, providing high compression ratios. The files compressed by this tool typically have a .7z extension.

Usage:
```
7z a archive_name.7z file1 file2 dir1
```
p7zip: This is a Unix port of 7-Zip, providing the 7z and 7za commands.
7z Extraction:
```
7z x archive_name.7z
```
