My friend keep forgetting the command to zip & extract  a folder in Linux , he use to ask me atleast once in a week. bcoz of him I am writing here , how to zip and unzip in linux.

>>       zip – package and compress (archive) files

# zip silence silence.zip

or more concisely

# zip -r silence.zip silence

>> unzip – list, test and extract compressed files in a ZIP archive

To  use unzip to extract all members of the archive letters.zip into the current directory and subdirectories below it, creating any subdirectories as
necessary:

# unzip silence.zip

To extract all members of letters.zip into the current directory only:

# unzip -j silence.zip
