I'd like to retrive a list excluding the first 2 lines

$ pip list
Package Version 
---------------------------------- ---------
alabaster 0.7.10 
anaconda-client 1.6.9 
anaconda-navigator 1.7.0 
anaconda-project 0.8.2 
appnope 0.1.0 
appscript 1.0.1 
asn1crypto 0.24.0 
astroid 1.6.1 
astropy 2.0.3 
attrs 17.4.0 

How to cut off the first two line like:

pip list | cut line=2

Simply with the sed command:

pip list | sed '1,2d'

Explanation: The sed command deletes (d) lines in the range 1 to 2 (and outputs everything else).

Or awk:

pip list | awk 'NR > 2'

Explanation: The awk program outputs everything on line 3 onwards.

awk would be particularly useful if you are planning to do further parsing of that output, such as extracting only the package names:

pip list | awk 'NR > 2 print $1 '

The cut command, that you mention in the question (disregarding that the semantics used is wrong), does not cut lines. Well, it does, but it cuts fields out of lines.

Simply with tail command:

pip list | tail -n+3 -

• from tail signature tail [OPTION]... [FILE]... - when FILE is -, read standard input


• 
  -n, --lines=[+]NUM - output the last NUM lines, instead of the last 10; or use -n +NUM to output starting with line NUM
