Maybe I am missing something, but here I go anyways Smilie
Rather than deleting lines from files that do not exist, why not rewrite your index.txt with files that DO exist?
Code:
#!/bin/sh

# remove index.tx1 (notice tx1 instead of txt)
rm index.tx1

# Read index.txt file
while read l; do
	f=$(echo "$l" | cut -d'|' -f8)
        # if file exists write it in index.tx1
	[ -f "$f" ] && echo "$l" >> index.tx1
done < index.txt

exit 0

At this point, index.tx1 contains only existing files.
index.txt still contains files that may be deleted.

ZIPARCHIVE.ADDFILE(3)							 1						     ZIPARCHIVE.ADDFILE(3)

ZipArchive::addFile - Adds a file to a ZIP archive from the given path

SYNOPSIS
bool ZipArchive::addFile NULL (string $filename, [string $localname], [int $start], [int $length]) DESCRIPTION
Adds a file to a ZIP archive from a given path. PARAMETERS
o $filename - The path to the file to add. o $localname - If supplied, this is the local name inside the ZIP archive that will override the $filename. o $start - This parameter is not used but is required to extend ZipArchive. o $length - This parameter is not used but is required to extend ZipArchive. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
This example opens a ZIP file archive test.zip and add the file /path/to/index.txt. as newname.txt. Example #1 Open and add <?php $zip = new ZipArchive; if ($zip->open('test.zip') === TRUE) { $zip->addFile('/path/to/index.txt', 'newname.txt'); $zip->close(); echo 'ok'; } else { echo 'failed'; } ?> NOTES
Note When a file is set to be added to the archive, PHP will lock the file. The lock is only released once the ZipArchive object has been closed, either via ZipArchive::close or the ZipArchive object being destroyed. This may prevent you from being able to delete the file being added until after the lock has been released. PHP Documentation Group ZIPARCHIVE.ADDFILE(3)
