You've chosen an excellent set of tools for the job!

Generating a list of files you want to edit is very simple - I'm here assuming you're using a shell which will expand the output of matching filenames, such as bash, or dash:

echo /home/*/site/assets/.htaccess > list.txt

However, if * can mean more than 1 level of directories, I would go with this:

find -name '.htaccess' /home | grep '/site/assets/sym' > list.txt

Your shell will expand the expression into a list, and redirect the output to list.txt. One file for each line.

You can also search for files named .htaccess with find - to see if there's anyone that you've missed, like this:

find -name '.htaccess' /home

Adding line breaks in replace text - this depends a bit on your editor. Line breaks are usually represented as \n

What you want to do, can probably be achieved with a small shell-script - when for variable in expression; do .... done is used, it will execute the lines in between do/done once for each word in expression. NOTE: This can backfire if the paths contain spaces.

for file in /home/*/site/assets/.htaccess; do
    sed 's/RewriteRule \^(.\*)\$ \/site\/assets\/sym\/\$1 \[L,NS\]/RewriteCond %{REQUEST_URI} !^\/site\/assets\/sym\nRewriteRule \^(.\*)\$ \/site\/assets\/sym\/\$1 \[L,NS\]/g' $file > $file.new
    mv $file $file.old
    mv $file.new $file
done

(This will leave a file named .htaccess.old in its spot.)

Rewritten for alternate list-gathering-approach:

for file in $(find -name '.htaccess' /home | grep '/site/assets/sym'); do
    sed 's/RewriteRule \^(.\*)\$ \/site\/assets\/sym\/\$1 \[L,NS\]/RewriteCond %{REQUEST_URI} !^\/site\/assets\/sym\nRewriteRule \^(.\*)\$ \/site\/assets\/sym\/\$1 \[L,NS\]/g' $file > $file.new
    mv $file $file.old
    mv $file.new $file
done

Or, in one line, without taking a backup:

for file in /home/*/site/assets/.htaccess; do sed -i 's/RewriteRule \^(.\*)\$ \/site\/assets\/sym\/\$1 \[L,NS\]/RewriteCond %{REQUEST_URI} !^\/site\/assets\/sym\nRewriteRule \^(.\*)\$ \/site\/assets\/sym\/\$1 \[L,NS\]/g' $file; done

Вы можете использовать sed для вставки строки над совпадающим шаблоном и создания резервных копий по ходу дела. 

for file in  $( find /home -name .htaccess | grep /site/assets/sym); do
    sed -i.bak '/RewriteRule \^(.\*)\$ \/site\/assets\/sym\/\$1 \[L,NS\]/i RewriteCond %{REQUEST_URI} !^/site/assets/sym' "$file"
done
  • sed -i.bak отредактирует файлы на месте и создаст файл .bak для каждого
  • / PATTERN / i другого шаблона - сопоставить PATTERN и вставить другой шаблон перед этим.
