unzipsfx: Create a self-extracting binary file of a `zip` archive.

$ cat unzipsfx ${path-to-archive-zip} > ${filename} && chmod 755 ${filename}

try on your machine

This command has multiple parts that are executed sequentially using the logical operator "&&":

cat unzipsfx ${path-to-archive-zip}: This uses the "cat" command to display the content of the file "unzipsfx" which is usually a self-extracting script. This script will be used to extract the contents of the specified archive in the next step. ${path-to-archive-zip} should be replaced with the actual path to the archive file.
> ${filename}: The "> " symbol is used for output redirection. It redirects the output of the previous command (the displayed content of "unzipsfx") to a file named ${filename}. You should replace ${filename} with the desired name for the output file.
&&: This is a logical operator that ensures the next command is executed only if the previous command succeeds.
chmod 755 ${filename}: This command changes the permissions of the ${filename} file to be executable by the owner, and readable and executable by everyone else. It sets the file's permissions to "rwxr-xr-x".

In summary, this command displays the content of the "unzipsfx" script, redirects that output to a file named ${filename}, and then changes the permissions of that file to be executable.
