Notations to check conditions 

• The comparison of string or numeric is the main decision taken to check for certain condition.
• The comparison like equal to, not equal, less than, greater than, less than or equal, greater than or equal, etc
• These can also be represented in bash as 
• equal to             :  -eq
• not equal           :  -ne
• greater than       :  -gt
• less than            :  - lt
• greater or equal :  -ge
• less or equal      :  -le 

• These will help greatly when using loops.
• The way of using these format in conditional statement are similar to https://cybercheck123.blogspot.com/2022/05/bash-scripting-6.html
• The only change is to replace these notation instead of symbols.
• Examples :
  
  

  

  
  

  

  
  

  
  

  
  
• Here if we use -eq the output will change because this is string comparison.The Notations will help to compare arithmetics.
