# 1. first rebase all your local commits into one commit, e.g. for the last 3 commits into one you can use

git rebase -i HEAD~3

# and 'pick' the first, 'squash' the other commits

# 2. check the commit's sha id and save it somewhere

git config --global user.name "John Doe"
git config --global user.email [email protected]
git config --global color.ui true

# select one of the 2 file versions during a merge
git checkout --ours index.html
git checkout --theirs _layouts/default.html

# see history in a nice tree form without gitk
git log --pretty=oneline --graph --decorate --all

# git add all including the renamed files without loosing history of the deleted file (as a rename implicitly looks like delete file and create new file)
git add . -A

1. Select new launch configuration

2. use /usr/bin/nohup for location

3. leave the working directory empty

4. for argument enter:
gnome-terminal --working-directory=${resource_loc}

5. Save and then you are able to run it while having different locations selected in package explorer: this will open the terminal in the corresponding directories

# run:
sudo netstat -lpn |grep :8080

# this will output something like:

tcp6       0      0 :::8080                 
:::*                    LISTEN      6782/java

# interpretation:
