从关联数组中删除数组元素要使用一个特殊的命令： delete array[index] delete命令会从关联数组中删除索引值及其相关的数组元素值： $ gawk ‘BEGIN{ > var[“a”] = 1 > var[“g”] = 2 > for (test in var) > { > print “Index:",test,” - Value:",var[test] > } > delete var[“g”] > print “—” > for (test in var) > print “Index:",test,” - Value:",var[test] > }’ Index: a - Value: 1 Index: g - Value: 2 #
Index: a - Value: 1 $ 一旦从关联数组中删除索引值，就不能再用它来提取数组元素值了。
