Trying to add some lines to a file.

I know I need to find this line:

<a href="tv/recorded"><?php echo t('Recorded Programs') ?></a>

Then add these two lines underneath that line, each on it's own line

  |  
<a href="episode"><?php echo t('TV Episodes') ?></a>

I know SED would be the way to do so, but I have yet to find an example that I understand. Could someone please provide me with the proper sed statement to add to a bash script to automate this. I have to re-add these after each software update and this would make it easier.

Handling HTML/PHP with sed is always a PITA - but it would be hard to come up with a more pathological example than that (double quotes AND single quotes in the pattern, as well as the usual special characters like / and ?). You will need to escape or bracket (turn into literal character ranges) those - which you do where is partly a matter of style. I *think* that these work:

1) using the sed append (a) command

$ sed "/<a href=\"tv\/recorded\"><[?]php echo t('Recorded Programs') [?]><\/a>/a\your first new line\nyour second new line" yourfile

2) with the more common sed substitute (s) command (can get rid of the escapes of the slashes by using a different character such as | as the separator)

$ sed "s|<a href=\"tv/recorded\"><[?]php echo t('Recorded Programs') [?]></a>|&\nyour first new line\nyour second new line|" yourfile

I was able to get the second one to "work", but it just spits the content out to the console. How would I have it write it back to the file?

sed "s|<a href=\"tv/recorded\"><[?]php echo t('Recorded Programs') [?]></a>|&\n\&nbsp\; \| \&nbsp\;\n<a href=\"episode\"><[?]php echo t('TV Episodes') [?]></a>|" header.php

add -i switch for in-place modification

Thanks. I swear I looked at the online documentation for sed and didn't see that. I guess new stuff is often overwhelming at first.
