Installation instruction deleted all my work

[ivanvanderbyl]

I just tried following the installation instructions, however it deleted not only my project, but everything in the parent directory.

git checkout --orphan gh-pages && rm -rf `ls -a | grep -vE '\.gitignore|\.git|node_modules|bower_components|(^[.]{1,2}/?$)'` && git add -A && git commit -m "initial gh-pages commit"

I'm shell zsh, so maybe something in here which doesn't work as expected.

It should create a blank gh-pages branch, so it might look like it broke your current branch. Try git branch to see which ones you have and the current one.

[ivanvanderbyl]

Unfortunately it wiped my whole directly, including the .git directory, and everything in ../*

[ivanvanderbyl]

I'm thinking the grep -vE ... doesn't work as expected for some reason.

[knownasilya]

Weird, did it at least create the gh-pages branch? Commands work left to right, and that's the first command before the grep and rm.

[knownasilya]

If you figure it out, please submit a PR for other zsh users.

[ivanvanderbyl]

Well I'd like to be able to verify it, but because it deleted the .git directory there is no way to know.

[knownasilya]

😢

[knownasilya]

I hope you committed your changes first..

[ivanvanderbyl]

Luckily this repo was up to date, unfortunately in the parent directory was my EmberConf talk source code, which wasn't released yet :(.

So I figured out why this happens:

ls -a | grep -vE '\.gitignore|\.git|node_modules|bower_components|(^[.]{1,2}/?$)'

See the problem?

[ivanvanderbyl]

So it looks like I have ls aliased to ls -laGF for simplicity. I'd recommend exec'ing this with a bash -c

[ivanvanderbyl]

$ bash -c "ls -a | grep -vE '\.gitignore|\.git|node_modules|bower_components|(^[.]{1,2}/?$)'"

.bowerrc
.editorconfig
.ember-cli
.jshintrc
.npmignore
.travis.yml
.watchmanconfig
LICENSE.md
README.md
addon
app
bower.json
config
ember-cli-build.js
index.js
package.json
testem.js
tests
vendor

Or even sh to be sure.

[knownasilya]

Just that portion, or the whole command?

[ivanvanderbyl]

This seems to do the job:

git checkout --orphan gh-pages && rm -rf `bash -c "ls -a | grep -vE '\.gitignore|\.git|node_modules|bower_components|(^[.]{1,2}/?$)'"` && git add -A && git commit -m "initial gh-pages commit"
