I have a grep routine for inserting some text into a large quantity of htm files. I am doing okay, with one exception. I don't seem to be able to grep and find the following string to insert some text just prior to it:
<div class='header'>
Here's a function that works to insert the contents of a text file just before the </head> in a group of htm files:
for file in *.htm ; do
while read line
do
grep -q "</head>" <<<$line && cat jsinsert.txt >> "$file".tmp
echo $line >> "$file".tmp
done < "$file"
doneHowever if I try to insert the contents of a file just before the <div class='header'> in a file (there's only one instance of this in each file) I cannot do it. I am wondering if it has something to do with the single quotes in the string.
Here's the target line I am searching for and my code that fails to find <div class='header'> in that line.
<div class="recipe"><img src="pics/13.jpg"><div class='header'><p class='Title'><span class='label'>Title:</span> Almond Puff Coffeecake</p>
This is my routine that fails:
for file in *.htm ; do
while read line
do
grep -q "<div class='header'>" <<<$line && cat divname.txt >> "$file".tmp
echo $line >> "$file".tmp
done < "$file"
done
The contents of divname.txt is simply a line containing <div id="print_div1">
I get the temp file but it's an exact duplicate of the original file. No info is inserted just prior to <div class='header'>
?????
<div class='header'>
