2. Split file into multiple files with 3 lines each: 

$ split -l 3 file

The option -l specifies the number of lines per output file. Since the input file contains 7 lines, the output files contain 3, 3 and 1 respectively. The output files generated are: 

$ ls x*
xaa  xab  xac
$ cat xaa
Unix
Linux
AIX

  The file "xab" contains the 4th till 6th line, and the file "xac" contains the last line.
