Head (Unix)

Head (Unix)

head is a program on Unix and Unix-like systems used to display the first few lines of a text file or piped data. The command syntax is:

head

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 -n 20 filename

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

head -n 5 foo*

Some versions omit the n and just let you say -5.
