    <p>Structure of Git repo foo in master branch </p> <pre><code>foo/refs/a.txt foo/bar/refs/b.txt </code></pre> <p>In other branches <code>refs/</code> might be in lots of other places</p> <h3>Goal</h3> <p>To remove all instances of the directory refs (and their content) from Git (history) Environment: Windows 7 using Git Bash</p> <h3>Removing refs (Git not involved, tried this just to see that it works by itself)</h3> <pre><code>find . -name refs -depth -exec rm -rf {} \; </code></pre> <p>Success, all <code>refs/</code> and their content are removed (If I don't use <code>-depth</code>, find will report an error that the dirs don't exists even though they were removed correctly).</p> <h3>Removing refs from Git</h3> <pre class="lang-bash prettyprint-override"><code>git filter-branch --index-filter \ 'find . -name refs -depth -exec git rm -rf --cached --ignore-unmatch {} \;' \ --prune-empty --tag-name-filter cat -- --all </code></pre> <p><img src="https://i.stack.imgur.com/Y5doo.png" alt="Removing directory refs from Git by rewriting the Git history"></p> <p>As can be seen in the picture (think of <code>temp/a</code> as <code>temp/foo</code>) the command runs through and rewrites all commits but no <code>refs/</code> are removed so somehow the output of the find is not returned to <code>filter-branch --index-filter</code> as expected.</p> <p>Similar things seem to work for others.<br> What am I missing?</p> <p>PS. Yes I've read hundreds of posts, articles etc for hours and hours about this but it doesn't work for me anyway.</p>

    1. COAnd with a ' ` | xargs -d'\n' ...` ', would that work better? As in `git filter-branch --index-filter 'find . -name refs -depth | xargs -d '\n' git rm -rf --cached --ignore-unmatch' --prune-empty --tag-name-filter cat -- --all`

    3. COright the msysgit `xargs` is an old 4.1 from 2004 instead of a 4.4 from 2009: no `--delim` option back then. You can try without the delimiter, but I fear it takes the all `find` result as *one* line...

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.
