blocks|key|3620467|text|sed+-r可以通过一些修改来处理它：[0-9]代替\d，<space>代替\s。没有真正的理由去捕捉第一和第三部分，所以我删除了这些组。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3620468|sed+-r+-e+'s/.*(AS[0-9]%2B)+([%5E"]%2B).*/"\1","\2"/'|code-block|syntax|javascript|3620469|或者，如果要完全匹配这些字符类，请使用[[:digit:]]表示\d，使用[[:space:]]表示\s|3620470|sed+-r+-e+'s/.*(AS[[:digit:]]%2B)[[:space:]]([%5E"]%2B).*/"\1","\2"/'|3620471|或者，您可以使用比csvtool更适合解析CSV文件的csvtool。|3620472|csvtool+col+3+input.txt+%7C+while+read+number+name;+do

<code>sed -r</code> can handle it with a few modifications: <code>[0-9]</code> instead of <code>\d</code> and <code>&lt;space&gt;</code> instead of <code>\s</code>. There's no real reason to capture the first and third parts, so I've removed those groups.

<pre><code>sed -r -e 's/.*(AS[0-9]+) ([^"]+).*/"\1","\2"/'
</code></pre>

Or if you want to match those character classes exactly, use <code>[[:digit:]]</code> for <code>\d</code> and <code>[[:space:]]</code> for <code>\s</code>:

<pre><code>sed -r -e 's/.*(AS[[:digit:]]+)[[:space:]]([^"]+).*/"\1","\2"/'
</code></pre>

Alternatively, you could use <code>csvtool</code> which is more suited to the job of parsing CSV files than <code>sed</code> is.

<pre><code>csvtool col 3 input.txt | while read number name; do
 printf '"%s","%s"\n' "$number" "$name"
done
</code></pre>

blocks|key|3620547|text|sed是最好的选择，但是FYI在GNU+awk中可以使用几乎精确的RE来完成这项工作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3620548|$+awk+'match($0,/.*(AS[0-9]%2B)\s([%5E"]%2B).*/,a){printf+"\"%25s\",\"%25s\"\n",+a[1],+a[2]}'+file
"AS24155","Asia+Pacific+Broadband+Wireless+Communications+Inc"|code-block|syntax|javascript|3620549|您的原始命令可能失败了，因为只有一些工具接受\s而不是[[:space:]]，而几乎没有一个工具接受\d而不是[[:digit:]]+(或[0-9])。|offset|length|style|CODE|3620550|entityMap^0|0|0|M|2|R|B|1E|2|1J|B|1X|5|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]|$I|T|J|U|K|L]|$I|V|J|W|K|L]|$I|X|J|Y|K|L]|$I|Z|J|10|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|11|8|@]|9|@]|A|$]]]|N|$]]

sed is the best choice for this but FYI here's how you could use almost your exact RE in GNU awk to do the job:

<pre><code>$ awk 'match($0,/.*(AS[0-9]+)\s([^"]+).*/,a){printf "\"%s\",\"%s\"\n", a[1], a[2]}' file
"AS24155","Asia Pacific Broadband Wireless Communications Inc"
</code></pre>

Your original command was probably failing because only some tools accept <code>\s</code> instead of <code>[[:space:]]</code> and almost none accept <code>\d</code> instead of <code>[[:digit:]]</code> (or <code>[0-9]</code>).

I have this input text

<pre><code>16789248,16789759,"AS24155 Asia Pacific Broadband Wireless Communications Inc"
</code></pre>

I want this text

<pre><code>"AS24155","Asia Pacific Broadband Wireless Communications Inc"
</code></pre>

This regex matches

<pre><code> /(.*)(AS\d+)(\s)([^"]+).*/g
</code></pre>

with this substitution <code>"$2","$4"</code>

I have to process 300k lines and it would be best if I was able to use a linux based command line utility like sed or awk...but I keep getting no matches or matches even though the regex seems to match elsewhere. 

Should I be using something different?
