head is a Computer program on Unix and Unix-like systems used to display the first few lines of a text Computer file or pipe (computing)d data. The command-syntax is:

head [options]

By default, head will print the first 10 lines of its input to the standard output. The number of lines printed may be changed with a command line option. The following example shows the first 20 lines of filename :

head -20 filename

This displays the first 5 lines of all files starting with foo :

head -5 foo*
