To retrieve the last x characters of a string in Bash, you can use the following syntax:
${string: -x}
Here, the variable string
contains the string from which you want to retrieve the last x characters. The -x
specifies the number of characters you want to retrieve, counting from the end of the string. The space in between :
and -x
is important.
For example, if you want to retrieve the last four characters of a string hello world
, you can use the following command:
$ echo ${string: -4}
This will output orld
.
