This happens to not be the case for any of the sample input strings provided by these answerers (how convenient...), but of course that doesn't change the fact that any code base that used this idiom would then run the risk of blowing up if this assumption were ever violated at some point down the line. Unlike in many other programming languages, in bash, an array is not a collection of similar elements. If you're in search of a solution to a multi-character delimiter problem, I suggest reviewing Mallikarjun M's post, in particular the response from gniourf_gniourf In a Bash script I would like to split a line into pieces and store them in an array. The value of the $IFS variable is not taken as a single variable-length string separator, rather it is taken as a set of single-character string separators, where each field that read splits off from the input line can be terminated by any character in the set (comma or space, in this example). You might think to yourself, well why not just add a no-op command word to the statement like the : builtin to make the $IFS assignment temporary? bash: Passing arrays with spaces. Unfortunately, there's no direct way to get a multicharacter delimiter to work.

Lastly, I wanted to demonstrate my own fairly intricate trimming solution using the obscure -C callback option of readarray. This function has been DEPRECATED as of PHP 5.3.0. To get the number of elements in an array: As mentioned above, arrays can be sparse so you shouldn't use the length to get the last element. Basically, for non-default non-null values of $IFS, fields can be separated with either (1) a sequence of one or more characters that are all from the set of "IFS whitespace characters" (that is, whichever of , , and ("newline" meaning line feed (LF)) are present anywhere in $IFS), or (2) any non-"IFS whitespace character" that's present in $IFS along with whatever "IFS whitespace characters" surround it in the input line.
