While collaboration, you may need to pull, commit, and push in CLI. Followings are bash scripts I use in my system.

Fetch all the source codes in the current repository

git_fetch.sh
#!/bin/bash
sudo -u apache git branch --set-upstream-to=origin/master master
sudo -u apache git fetch --all
sudo -u apache git pull


Pull in the current repository

git_pull.sh
#!/bin/bash
sudo -u apache git branch --set-upstream-to=origin/master master
sudo -u apache git pull


Fetch codes and Merge in the current repository

git_merge.sh
#!/bin/bash
sudo -u apache git branch --set-upstream-to=origin/master master
sudo -u apache git fetch --all
sudo -u apache git merge origin master


Commit codes in the current working directory

git_commit.sh
#!/bin/bash
echo Please input your commit message below \(blank to put as "bug fix"\)
read commit
sudo -u git branch --set-upstream-to=origin/master master
sudo -u apache git pull
sudo -u apache git add .
if [ ! "$commit" ]; then
        sudo -u apache git commit -m "bug fix"
else
        sudo -u apache git commit -m "$commit"
fi
sudo -u apache git push
sudo -u apache git pull


Clean codes in the current working directory

git_clean.sh
#!/bin/bash
echo Please input your clean up message below \(blank to put as "clean up commit messages"\)
read commit
sudo -u apache git branch --set-upstream-to=origin/master master
sudo -u apache git checkout --orphan latest_branch
sudo -u apache git add -A
if [ ! "$commit" ]; then
        sudo -u apache git commit -am "clean up commit messages"
else
        sudo -u apache git commit -am "$commit"
fi
sudo -u apache git branch -D master
sudo -u apache git branch -m master
sudo -u apache git push -f origin master
