使用 sed 替换 URL 的十六进制代码并在所有 SVG 文件中的 SVG 标记后插入新的 SVG 代码

  • 772

我想 ...

  • 替换所有 SVG 文件中 URL (id) 的十六进制代码
  • <svg ...>使用 Regex在 之后插入/添加新的 SVG 代码行。

输入：

这是我的shell脚本：

for i in *.svg; 
    do sed --in-place --follow-symlinks 's/#5c616c/url(#grad1)/' "$i"
done;

for i in *.svg; 
    do sed --in-place --follow-symlinks '/(svg)([^<]*|[^>]*)/ag <linearGradient id="grad1" x1="0%" y1="0%" x2="100%" y2="0%"> <stop offset="0%" style="stop-color: rgb(255, 255, 0); stop-opacity: 1"\/> <stop offset="100%" style="stop-color: rgb(255, 0, 0); stop-opacity: 1"\/> <\/linearGradient>' "$i"
done;

在一行中：

for i in *.svg; do sed --in-place --follow-symlinks 's/#5c616c/url(#grad1)/g; /(svg)([^<]*|[^>]*)/a <linearGradient id="grad1" x1="0%" y1="0%" x2="100%" y2="0%"> <stop offset="0%" style="stop-color: rgb(255, 255, 0); stop-opacity: 1"\/> <stop offset="100%" style="stop-color: rgb(255, 0, 0); stop-opacity: 1"\/> <\/linearGradient>' "$i"; done

我的命令不好，因为它替换并插入了一些 SVG 文件，并破坏了其他文件。

我有一个名为 Breeze 的图标主题。首先，我想找到一个图标主题在/usr/share/icons/breeze,/home/$USER/.icons/breeze或/home/$USER/.local/share/icons/breeze中，如果找到，我将cd它替换并插入多个文件夹（不是所有文件夹）中的所有 SVG 文件中。三个文件夹apps/16：mimetypes/16和places/16。

是否可以重新调整文件中链接派生的这些代码replace-all.sh？

    如果我理解正确，你想做两件事：

    1. 替换#5c616c为url(#grad1)。

    2. <svg ...>在开始标记之后插入这些行：

      <linearGradient id="grad1" x1="0%" y1="0%" x2="100%" y2="0%">
  <stop offset="0%" style="stop-color:rgb(255,255,0);stop-opacity:1" />
  <stop offset="100%" style="stop-color:rgb(255,0,0);stop-opacity:1" />
</linearGradient>

    就个人而言，我会在 Perl 中完成所有工作：

    #!/bin/perl
my $replacement=<<EoF;
<linearGradient id="grad1" x1="0%" y1="0%" x2="100%" y2="0%">
  <stop offset="0%" style="stop-color:rgb(255,255,0);stop-opacity:1" />
  <stop offset="100%" style="stop-color:rgb(255,0,0);stop-opacity:1" />
</linearGradient>
EoF
## This is just to fix SE's syntax highlighting /    
my $foundSvg = 0;
while (<>) {
  ## Insert the replacement after the 1st line matching '<svg'
  if (/<\s*svg/) {
    $foundSvg++;
  }
  if ($foundSvg == 1) {
    ## $_ is the value of the current line. If we have found the <svg,
    ## append $replacement to this line
    $_ .= $replacement;
    ## Increment $foundSvg so we don't do this twice
    $foundSvg++;
  }
  ## For all lines, replace all occurrences of #5c616c with url(#grad1)
  s/#5c616c/url(#grad1)/g;
  ## Print the line
  print;
}

    将其保存为foo.pl然后：

    for f in *svg; do
   perl foo.pl "$f" > tmpFile && mv tmpFile "$f"
done
