Read & Display Single Line of a File

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.

  1. Sweet Binny! There are always multiple ways to do things in Linux and it’s fantastic to be able to have so much versatility at your fingertips 🙂 Thanks for the extra tip 😀

  2. xargs -i -t -exec grep -i -w {} file_1 >>test < file_2

    This was meant to search for the contents of file_2 in file_1 and write the respective lines into file"test" . But instead it writes
    grep -i -w "string1" File_1
    grep -i -w "string2" File_1
    grep -i -w "string3" File_1
    to the standard output and creates an empty file "test"
    Any ideas why this doesn't work?
    Your help is very much appreciated
