脊髓案例，以案例的骆驼 [英] Spinal Case to Camel Case

问题描述

我的问题是pretty的这么多相反：<一href=\"http://stackoverflow.com/questions/8502977/linux-bash-camel-case-string-to-separate-by-dash\">linux庆典，骆驼字符串由​​破折号分开

My question is pretty much the opposite of this: linux bash, camel case string to separate by dash

pretty热切采取部分串样这样到 SomeStringLikeThis 。

Pretty much looking to take some-string-like-this to SomeStringLikeThis.

任何人都得到了一些 SED 魔法还是很容易这样做的其他方式？

Anyone got some sed magic or other means of doing this easily?

作为一个方面说明，我的一部分认为，作为流行Bash是，这有可能是一个图书馆，在那里，可以像这样转换的帮助...我还没有找到一个，但。如果你知道的人，请让我知道。例如这将处理标准的命名风格，如脊柱强调之间的共同字符串操作/转换出库，强调以骆驼，骆驼脊柱等。

As a side note, part of me thinks that as popular as Bash is, that there might be a library out there that could help with conversions like this... I haven't found one though. If you know of one, please let me know. e.g. a library that would handle common string manipulations/conversion between standard naming styles, such as spinal to underscore, underscore to camel, camel to spinal, etc.

推荐答案

这适用于GNU sed的：

This works with GNU sed:

sed -r 's/(^|-)(\w)/\U\2/g'

匹配线或的开始 - 后面跟着一个字母数字字符，并使用 \\ U 来使字符大写。

Match the start of the line or a - followed by an alphanumeric character and use \U to make the character uppercase.

这是几乎相同的在Perl：

It's almost identical in perl:

perl -pe 's/(^|-)(\w)/\U$2/g'

只是为了好玩，这里有一个方法，你可以做它在本地的bash：

Just for fun, here's a way you could do it in native bash:

spinal_to_upper() {
    IFS=- read -ra str <<<"$1"
    for s in "${str[@]}"; do 
        printf '%s' "${s^}"
    done
}

spinal_to_upper "some-string-like-this"
