When you use cut command then it takes two main arguments
-d : which stand for delimiter
-f : which stand for field to be cut from the input file
Ex. cut - d "|" - f1, 2 input_filename
Here the output would be separated by delimiter "|" and it will cut only 2 fields from the input file
If you have following lines in your file
Alex|120000|Admin|1999
Then it will cut 2 fields which are
Alex|120000
