I had a requirement where I had to execute shell command from PHP. The requirement was that I had to find details of a domain using commands like whois and then store this information into files in a folder. The only input parameter for the process was the name of the domain which was passed on from the Drupal site. The PHP function (shell_exec) was designed to do things like this.
Here is a script to help you find empty directories located under a specified parent-folder. The file folders.txt contains the list of folders that are to be passed as input to the script. The script will now check all the folders mentioned in the file folders.txt, and give the list of folders that are empty.
This is a script to create a particular directory under all subdirectories in a parent directory. Consider the case when a parent directory consists of more than 100 folders and you want create a new folder under all these directories, with the same name. Doing this manually would be a mess. This script would help you do this in no time.
We had sometime back released an automatic login script for Asianet broadband connections. We had since then signed up for Reliance broadband at one of our offices and had to set up something to connect to the connection automatically. The auto login script for Reliance broadband that we created has been published via our github account as Free Software under GPL.
Asianet Dataline is an ISP in Kerala and they use a web browser based authentication system to log the user onto their network. One of their most popular plans the - Homenet 475 offers free unlimited downloads from 2AM to 8AM. Now if there was a way to turn on your system at 2AM, automatically login to Asianet and turn your download manager on and then shutdown at 8AM it would have been perfect. The only problem is that the http based authentication system makes it a bit unwieldy to automate. Well not really :-). We have created a bash script to automate this login process.
cd ~username. We had some extra time on our hands and wanted to play with the /etc/passwd file and tried to use awk to do the same thing. The following one liner will do this the hard way :-)
