isset() PHP function in cgi bash scripts
Hi!
Some minutes ago I've posted a question related with sed regexps because I need to catch information sended with forms with GET action. This is the post:
https://www.unix.com/shell-programmin...ssion-sed.html
But now I have a new question. Does cgi scripts have an equivalent function to PHP isset() function? If I have a form with POST action that sends information to
another file there is no problem, but if I have to send it to the
same file, how can I determine if it's the first time that a user visits the page?
Thanks.
