    <p>I have some 100,000+ files with partially mangled data, mixed text+binary files (a single file of jpg image data with http headers), where some header fields have dos style ^M^J line termination, and some only unix style ^J. When vim opens a file like this, it treats it as unix format. So all header lines where there is no ^M, one needs to be added. But this has proven to be very tough. </p> <p><code>:1,11s/Cache-Control:.*\zs^M\{0,}$/^M/</code></p> <p>doesn't work, and i've tried all kinds of variations of that, even using \=printf("%s","^M") as substitution string. But the result is always a new empty line in the file.</p> <p>The ONLY way i'm able to add a ^M by a command at all is by</p> <p><code>:exe "normal A\&lt;c-q&gt;\&lt;c-m&gt;\&lt;Esc&gt;"</code></p> <p>Ok so one way would be to first remove any existing ^M, and then add it by previous. But is there a more elegant, one command solution?</p> <p>(So that there would be no more misunderstandings, here's a short example of such a file:</p> <pre><code>HTTP/1.1 200 OK Server: Apache/2.2.3 (more lines...) Cache-Control: public, max-age=214748 (more lines...) ÿØÿá Exif II* ÿì </code></pre> <p>)</p> <p>Edit/solution: regarding 100,000+ files, here's a version (regarding missing ^M only on cache-control lines) that only matches if ^M is missing (as not all files are mangled, this will save large amounts of time together with "update!"):</p> <p><code>:1,11s/^Cache-Control:.\{-}\zs\(^M*$\)\(^M\)\@&lt;!/\^M/i</code></p>

    1. COWouldn't it be easier to configure the program reading the files to be tolerant of either line ending style (only in the header section)?

    2. COIn this case it's not possible/wouldn't help. I'm doing this because i need to.

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.
