Debugging on part(s) of the bash script

Using the set Bash built-in you can run in normal mode those portions of the script of which you are sure they are without fault, and display debugging information only for troublesome zones. Say we are not sure what the w command will do in the example commented-script1.sh, then we could enclose it in the script like this.

You can switch debugging mode on and off as many times as you want within the same script.

Running CGI script from any directory

In order to force apache to allow cgi script to run, simply create a file called .htaccess inside the directory in which you wish to run the scripts. Inser this text into the file:

AddHandler cgi-script .cgi .pl

AddHandler maps the filename extensions extension to the handler handler-name. This mapping is added to any already in force, overriding any mappings that already exist for the same extension. For example, to activate CGI scripts with the file extension “.cgi”, you might use:

AddHandler cgi-script .cgi

Once that has been put into your srm.conf or httpd.conf file, any file containing the “.cgi” extension will be treated as a CGI program.

The extension argument is case-insensitive, and can be specified with or without a leading dot.

PHP as a CGI script with suexec

For hosts running PHP as a CGI script with suexec you may be able to put these directives in a php.ini file in your website root directory.

Add the below to your .htaccess file in your web root directory.

The PHP documentation states that the memory_limit setting also affects file uploading.
Generally speaking, memory_limit should be larger than post_max_size.

Depending on your host, this can be done in a number of places with the most likely being php.ini or .htaccess depending on your hosting situation.

Add for example:

With root access, you can use the sed util in Linux/Unix based systems, in order to increace the memory for 64M. Don’t forget to properly locate you php.ini file!
