Top Forums Shell Programming and Scripting BASH- Hold script until all contents of a file is written Post 302908932 by Michael Stora on Friday 11th of July 2014 03:17:50 PM

If you can't get the first applicaiton to manipulate a lockfile or otherwise signal your script, you can use incron (a cron like utility for file system events) to signal your second script that it is safe to read.

I use incron to detect the close file event for any file in my public ftp submission directory and as soon as it is done being uploaded, incron launches a script that yanks it away to a non-public directory so that every individual's uploads are private to other users whithout giving everyone a different area.

I also have a web interface to reboot my server, turn on and off anonymous FTP, share or not share my media directories (on/off or for a timeout period), etc. I know very little CGI, so instead of handling it in CGI, I save the state of the user radio button clicks and password hash to a text file and use Incron to detect a change and launch a shell script which parses and interperates it. I did it out of ignorance of CGI but I believe it is very secure.

AppConfig::CGI(3pm)					User Contributed Perl Documentation				       AppConfig::CGI(3pm)

NAME
AppConfig::CGI - Perl5 module for processing CGI script parameters. SYNOPSIS
use AppConfig::CGI; my $state = AppConfig::State->new(\%cfg); my $cgi = AppConfig::CGI->new($state); $cgi->parse($cgi_query); $cgi->parse(); # looks for CGI query in environment OVERVIEW
AppConfig::CGI is a Perl5 module which implements a CGI interface to AppConfig. It examines the QUERY_STRING environment variable, or a string passed explicitly by parameter, which represents the additional parameters passed to a CGI query. This is then used to update variable values in an AppConfig::State object accordingly. AppConfig::CGI is distributed as part of the AppConfig bundle. DESCRIPTION
USING THE AppConfig::CGI MODULE To import and use the AppConfig::CGI module the following line should appear in your Perl script: use AppConfig::CGI; AppConfig::CGI is used automatically if you use the AppConfig module and create an AppConfig::CGI object through the cgi() method. AppConfig::CGI is implemented using object-oriented methods. A new AppConfig::CGI object is created and initialised using the new() method. This returns a reference to a new AppConfig::CGI object. A reference to an AppConfig::State object should be passed in as the first parameter: my $state = AppConfig::State->new(); my $cgi = AppConfig::CGI->new($state); This will create and return a reference to a new AppConfig::CGI object. PARSING CGI QUERIES The "parse()" method is used to parse a CGI query which can be specified explicitly, or is automatically extracted from the "QUERY_STRING" CGI environment variable. This currently limits the module to only supporting the GET method. See AppConfig for information about using the AppConfig::CGI module via the cgi() method. AUTHOR
