Does `dash` support `bash` style arrays?

问题:

In the dash shell environment I am looking to split a string into arrays. The following code works in bash but not in dash.

IFS=""
var="this is a test|second test|the quick brown fox jumped over the lazy dog"
IFS="|"
test=( $var )
echo ${test[0]}
echo ${test[1]}
echo ${test[2]}

My Question

Does dash support arrays in this style. If not are there any suggestions for parsing this out into an another type of variable without the use of a loop?

回答1:

dash does not support arrays. You could try something like this:

var="this is a test|second test|the quick brown fox jumped over the lazy dog"
oldIFS=$IFS
IFS="|"
set -- $var
echo "$1"
echo "$2"
echo "$3"      # Note: if more than $9 you need curly braces e.g. "${10}"
IFS=$oldIFS
