Open SHAR File
SHAR, or Shell Archive file, is a self-extracting archive of files that are concatenated onto the single-file bundles and written in a shell script. Each file is encoded and packaged within the SHAR file so the content is preserved, ready to be deployed when needed. Supporting Unix and Linux systems, the SHAR file format is akin to a zip file in Windows [1].
Opening SHAR Files
Opening SHAR files depends mainly on the system being used. UNIX-based systems have built-in support for extracting SHAR files. To open a SHAR file on Unix or Linux, the user can use the 'sh' command in the terminal, followed by the name of the SHAR file. This will run the script and extract the files contained within the SHAR file [2].
SHAR Files in Data Transmission
Due to their capacity to hold multiple files in one, SHAR files are often used when transmitting bundles of files over networks or via email. They are especially useful where network protocols might not support the sending of file bundles or directories. Keeping all the necessary files in a single SHAR preserves the structure of the original data when sent over these protocols [3].
File Integrity with SHAR Files
In addition to keeping multiple files within one single file, SHAR also checks for file integrity upon extracting, meaning it verifies whether files have been modified or tampered with since they were originally bundled. This makes SHAR a secure way of transmitting data between Unix or Linux systems [4].
SHAR File Important Information
Working with SHAR files requires a basic understanding of Unix or Linux command line interfaces and, despite the simplicity of the process, should be done with care. Misuse can lead to accidental overwriting of files. In addition, though file transmissions using SHAR files are secure in their integrity checks, they lack the encryption that formats like Zip or RAR might offer. Knowing this, it's critical to balance the convenience of SHAR files with the necessity of data security [5].
