在shell脚本中标记字符串

Question

如何在shell脚本中标记字符串？
例如：给定字符串“a：b：c”和分隔符“：”，我想返回一个数组{a，b，c}
它等同于java的StringTokenizer。

Answer 1

var="a:b:c" 
OLDIFS=$IFS 
IFS=":" 
read -a array <<< "$(printf "%s" "$var")" 
IFS=$OLDIFS 
echo ${#array[@]} 
echo ${array[0]} 
echo ${array[1]} 
echo ${array[2]} 

Answer 2

echo "a:b:c" | awk -F":" '{print "{"$1",",$2",",$3"}"}'
