for循环范围不起作用ksh [英] for loop range not working ksh

问题描述

我尝试过了

#!/bin/ksh
for i in {1..10}
do
  echo "Welcome $i times"
done

AIX框的Ksh中的

. 我得到的输出是，

in Ksh of an AIX box. I am getting the output as,

欢迎{1..10}次

Welcome {1..10} times

这是怎么了? 它不是应该从1到10打印吗? 根据perkolator的帖子，来自迭代ksh中的一系列int?

What's wrong here? Isn't it supposed to print from 1 to 10?. According to perkolator's post, from Iterating through a range of ints in ksh?

它仅在linux上有效. unix box ksh还有其他解决方法吗?

It works only on linux. Is there any other work around/replacements for unix box ksh?

for i in 1 2 3 4 5 6 7 8 9 10

很丑.

谢谢.

推荐答案

我从内存中认为AIX上的标准ksh是较旧的变体.它可能不支持有范围的for循环.尝试使用ksh93而不是ksh运行它.该位置应与ksh在同一位置，可能是/usr/bin.

I think from memory that the standard ksh on AIX is an older variant. It may not support the ranged for loop. Try to run it with ksh93 instead of ksh. This should be in the same place as ksh, probably /usr/bin.

否则，只需使用一些老式的东西，如:

Otherwise, just use something old-school like:

i=1
while [[ $i -le 10 ]] ; do
    echo "Welcome $i times"
    i=$(expr $i + 1)
done

实际上，通过

Actually, looking through publib seems to confirm this (the ksh93 snippet) so I'd try to go down that route.
