I have a directory with many HTML documents. Most of them contain the codeblock

      .org-link {
        /* org-link */
        color: #b58900;
        font-weight: bold;
        text-decoration: underline;
      }

inside the <style type="text/css"> tag. I'd like to write a script that removes the line text-decoration: underline; from this block in every file.

Usually I would write a sed or perl one-liner to simply delete each instance of text-decoration: underline; but many of the documents have other instances of the line text-decoration: underline that I do not removed.

Is there a tool in linux that can easily do this?

Try this:

sed '/.org-link {/,/}/{/text-decoration: underline;/d}' file

Output:

      .org-link {
        /* org-link */
        color: #b58900;
        font-weight: bold;
      }

To edit your file "in place":

sed -i '/.org-link {/,/}/{/text-decoration: underline;/d}' file

  • I'm aware that sed or perl can do this. The problem is that there are other instances of text-decoration: underline; in the files that I don't want deleted. Maybe I should make this clear in my question. Commented Aug 24, 2015 at 6:01
  • Is there always a line with ".org-link {" to mark this block? Commented Aug 24, 2015 at 6:02
  • Yes. I want to delete the the first instance of font-weight: bold; after .org-link { Commented Aug 24, 2015 at 6:05

  • Out of curiosity, how could I adjust the code if I wanted to replace this instance of text-decoration: underline with text-decoration: bold? Commented Aug 24, 2015 at 6:10

Using gawk:

gawk -i inplace '/.org-link {/,/}/ {if($0~/text-decoration: underline/) next} {print}' infile

This will delete only text-decoration: underline attributes in a .org-link class:

user@debian ~ % cat infile
.org-link {
        /* org-link */
        color: #b58900;
        font-weight: bold;
        text-decoration: underline;
      }

.org-link1 {
        /* org-link */
        color: #b58900;
        font-weight: bold;
        text-decoration: underline;
      }

.org-link {
        /* org-link */
        color: #b58900;
        font-weight: bold;
        text-decoration: underline;
      }
user@debian ~ % gawk -i inplace '/.org-link {/,/}/ {if($0~/text-decoration: underline/) next} {print}' infile
user@debian ~ % cat infile
.org-link {
        /* org-link */
        color: #b58900;
        font-weight: bold;
      }

.org-link1 {
        /* org-link */
        color: #b58900;
        font-weight: bold;
        text-decoration: underline;
      }

.org-link {
        /* org-link */
        color: #b58900;
        font-weight: bold;
      }

To loop this over multiple HTML files in the same working directory, you can use a bash for loop with wildcards:

for f in *.html; do gawk -i inplace '/.org-link {/,/}/ {if($0~/text-decoration: underline/) next} {print}' "$f"; done
