The hash-bang "#!" is used in AJAX-based web applications to indicate that it has web crawler support. For the shell script shebang ("#!" at the start of a file), use the [shebang] tag instead.
"Hash-bang" is a nickname for the sequence "#!" (octothorpe, exclamation mark). It is used
in URLs to indicate that this is a AJAX-based web application with web crawler support
in Unix shell scripts to identify the executable that should be used to parse this file, e.g.
#!/bin/bash #!/usr/bin/perl -wto run a script with the bash shell or with Perl (in warnings mode) respectively. Use the shebang tag for these questions instead.
