Numeric and string comparisons in Shell scripting

The numeric comparisons for shell scripting are:

1. numA -eq numB - True if numA and numB are equal
2. numA -ne numB - True if numA and numB are not equal
3. numA -lt numB - True if numA is less than numB
4. numA -gt numB - True if numA is greater than numB
5. numA -le numB - True if numA is less than or equal to numB
6. numA -ge numB - True if numA is greater than or equal to numB

The string comparisons for shell scripting are:

1. strA = strB - True if strA matches strB
2. strA != strB - True if strA does not match strB
3. strA < strB - True if strA comes before strB in a dictionary order
4. strA > strB - True if strA comes after strB in a dictionary order
