求一句sed替換的shell

limaoyuan

想把url(中的/images/abc1.png?11)換成/136905/images/abc1.png?11。

我遇到了下面的問(wèn)題，如果在s參數(shù)中帶了問(wèn)號(hào)就匹配不到了


不能替換：
echo 'background-image: url("/images/abc1.png?11");' | awk -v s="/images/abc1.png?11" -v d="/136905/images/abc1.png" '{gsub(s,d)}1
輸出
'background-image: url("/images/abc1.png?11"); //沒(méi)被替換



能替換：
echo 'background-image: url("/images/abc1.png?11");' | awk -v s="/images/abc1.png" -v d="/136905/images/abc1.png" '{gsub(s,d)}1'
輸出
background-image: url("/136905/images/abc1.png?11"); //被替換了

加轉(zhuǎn)義試試：

1. awk -v s="/images/abc1.png\\?11" -v d="/136905/images/abc1.png" '{gsub(s,d)}1

復(fù)制代碼

    沒(méi)起作用。

echo 'background-image: url("/images/abc1.png\\?11");' | awk -v s="/images/abc1.png?11" -v d="/136905/images/abc1.png" '{gsub(s,d)}1'
輸出
background-image: url("/images/abc1.png\\?11");

你的\\寫(xiě)錯(cuò)地方了吧？？？？

1. awk -v s='/images/abc1.png\\?11' -v d="/136905/images/abc1.png" '{gsub(s,d)}1

輸出：
background-image: url("/images/abc1.png?11");

這樣也不行

我上面也寫(xiě)錯(cuò)了，應(yīng)該是：
    s="/images/abc1.png\\?11"  ==> s='/images/abc1.png\\?11'
或
   s="/images/abc1.png\\?11"   ==> s="/images/abc1.png\\\?11"

用sed唄，標(biāo)題不就是sed么

1. echo 'background-image: url("/images/abc1.png?11");'|sed 's#/images/abc1.png?11#/136905/images/abc1.png?11#g'

復(fù)制代碼

按樓主的寫(xiě)法應(yīng)該需要轉(zhuǎn)義

1. echo 'background-image: url("/images/abc1.png?11");' | awk -v s="/images/abc1.png\\\?11" -v d="/136905/images/abc1.png" '{gsub(s,d)}1'
