1. Vim basic configuration

   set nocompatible
    set columns=80
    set tabstop=4
    set ruler
    set expandtab
    set number
    set ignorecase
    set wrapmargin=15
    set cindent
    set shiftwidth=4
    syntax on

   Code coloring and display of line numbers:

2. The vim tab key is changed to four spaces.
   Set expandtab # use space instead of tab.
   Set tabstop = 4 # four spaces.
   Set shiftwidth = 4 # width of automatic indent.
3. Ssh backspace key (OT)
   After entering the python interaction, press the backspace key to display "^ H" instead of deleting characters.
   Option-> session option-> Terminal-> Emulation-> mapping keys other mappings check Backspace sends delete
4. Run jmeter without interface:
   JMeter-n-t "xxx. jmx"-l test. log
5. Use the OR, AND, NOT operators in the Linux grep command
   OR:
   1 grep 'pattern1 \ | pattern2 'filename
   2 The grep-E option can be used to extend the option to a regular expression. If you use option-E of the grep command, use | to separate multiple 3 pattern to implement the OR operation.
   4 The egrep command is equivalent to 'grep-e'
   AND:
   1 use-E 'pattern1. * pattern2'
   2 + grep
   NOT:
   Grep-v 'pattern1 'filename
