Sometimes when I’m troubleshooting a PHP error and a function is called in the debugger that gives me a line number of a file to look at, I want to know what that line says without opening up the file. Using the command line, you can accomplish this in the following way:
head -n 96 filename.php | tail -n 1
This allows you to quickly display the 96th line of filename.php. Hope this helps someone like it has me.
