Array and traversal in Linux Shell

When using shell in Linux, arrays are occasionally used for convenience. The declaration method of the array is:

Array = (element1 element2 element3... elementn)

That is, wrap the array elements directly with parentheses, and separate the array elements with spaces.

 

The data is read as follows:

# Echo $ {array [0]} <br/> # echo $ {array [Index]}

 

The traversal of the array uses one to retrieve all:$ {Array [@]}

Complete example:

For data in $ {array [@]} <br/> DO <br/> echo $ {data} <br/> done
