linux shell标题大小写 [英] linux shell title case

问题描述

我正在编写一个shell脚本，并有一个像这样的变量:something-that-is-hyphenated.

I am wrinting a shell script and have a variable like this: something-that-is-hyphenated.

我需要在脚本的各个方面使用它，例如:

I need to use it in various points in the script as:

something-that-is-hyphenated，somethingthatishyphenated，SomethingThatIsHyphenated

通过使用sed "s/-//g"剥离-，我设法将其更改为somethingthatishyphenated.

I have managed to change it to somethingthatishyphenated by stripping out - using sed "s/-//g".

我确信有一种更简单的方法，并且还需要知道如何获得骆驼套式版本.

I am sure there is a simpler way, and also, need to know how to get the camel cased version.

工作函数源自@Michał的答案

Working function derived from @Michał's answer

function hyphenToCamel {
    tr '-' '\n' | awk '{printf "%s%s", toupper(substr($0,1,1)), substr($0,2)}'
}

CAMEL=$(echo something-that-is-hyphenated | hyphenToCamel)
echo $CAMEL

最后，感谢@glenn

Finally, a sed one liner thanks to @glenn

echo a-hyphenated-string | sed -E "s/(^|-)([a-z])/\u\2/g"

推荐答案

GNU sed单线版

a GNU sed one-liner

echo something-that-is-hyphenated | 
sed -e 's/-\([a-z]\)/\u\1/g' -e 's/^[a-z]/\u&/'

中记录了替换字符串中的

\u sed手册.

\u in the replacement string is documented in the sed manual.
