问题描述
我有三种类型,我想在bash脚本大写的字符串。我想通SED / AWK将是我最好的选择,但我不知道。什么是给出了以下要求的最佳方式是什么?
I have three types of strings that I'd like to capitalize in a bash script. I figured sed/awk would be my best bet, but I'm not sure. What's the best way given the following requirements?
1)一个字
例如塔科 - >塔克
2)多个单词用连字符隔开
例如我的鱼,玉米饼 - >我-鱼炸玉米饼
2.) multiple words separated by hyphens e.g. my-fish-tacos -> My-Fish-Tacos
3)多个单词用下划线分隔
例如 my_fish_tacos - > My_Fish_Tacos
3.) multiple words separated by underscores e.g. my_fish_tacos -> My_Fish_Tacos
推荐答案
有没有必要使用捕获组(虽然&安培;
是一个的方式):
There's no need to use capture groups (although &
is a one in a way):
echo "taco my-fish-tacos my_fish_tacos" | sed 's/[^ _-]*/\u&/g'
输出:
Taco My-Fish-Tacos My_Fish_Tacos
越狱的小写字母U大写的匹配的子字符串中的一个字符。
The escaped lower case "u" capitalizes the next character in the matched sub-string.
