In our case, the script searches for the pattern-and replaces it with white space. The parenthesis around${addrs//-/ }are used to define an array of the new string, calledip_array. We use theforloop to iterate over all theip_arrayvariable elements and display them using theechocommand...
The part that split the string is here: IFS=';' read -ra my_array <<< "$my_string" Let me explain it to you. IFS determines the delimiter on which you want to split the string. In my case, it’s a semi colon. It could be anything you want like space, tab, comma or even ...
The last element is: string In this example, the sed command is used with the s (substitute) command to match everything before the last space character in the input string and replace it with nothing. In Bash, the sed command performs text transformations on the input text. The "s" cha...

The test cases here test both a simple string as a splitter (a space) and a simple regular expression (\s+, indicating some non-zero number of whitespace characters), as well as various values of the optional "limit" parameter. In summary, in all of the cases tried, the Java and Perl...
Like split and each, first_and_rest accepts nil or an empty string as special cases for the delimiter. nil is automatically transformed into '%s+', a generic "separated by space" pattern. In the case of an empty string delimiter, first_and_rest returns the first character of the input ...
In bash, the special shell variable $IFS is utilized for dividing a string into words. It is also known as Internal Field Separator (IFS and is used to specify the delimiter for splitting the string. Bash identifies word boundaries using $IFS, and by default, white space is the delimiter....
Here split is done on first space and rest of the string gets captured in 2nd element. In case there is no space, only one element array is returned. <?php $s="hello world. hello word.\n2ndline"; $arr = explode(" ", $s, 2); ...
