Let’s say we want to change our git username to another one. Instead of checking manually if the username is already taken, we can automate this process by writing a script named fgitusr. The content of the script looks like this:

Code

# Check regex rules
if [[ !("$1" =~ ^[0-9a-zA-Z]{1}[0-9a-zA-Z\-]*[0-9a-zA-Z]{1}$) ]]; then
    echo "$1 DOESN'T MATCH REGEX"
    exit 1
fi

# Check if usersname exists
curl --output /dev/null --silent  --head --fail "https://github.com/$1"
if [ $? -eq 0 ]; then
    echo "USER $1 EXISTS";
else
    echo "USER $1 DOESN'T EXIST";
fi

The main idea is that we use curl to look if the url https://github.com/<username> is a valid link. If it is, then the user exist.

This can be done by using curl and pandoc. The command looks like this:

curl <url> | pandoc -f html -t plain | less

After that you can go up and down with j and k keys. With this command you can read directly in the terminal. If you want to store the information in a text file, you could use this command:

curl <url> | pandoc -f html -t plain > file.txt

Where file.txt is the name of the file where the information is stored.

After a lot of typing my wrist started to hurt. So I done some research and found out that the best way to have you hand when typing is without resting your palms on you keyboard, basically keep your elbows up like a piano player…because in the long run can cause fatigue and also other wrist problems. After testing this method I am quite happy with the result and I will try to implement it more and more 😃.

Hugo is a great minimalistic tool for generating static websites. It took me one day to get a hang of it and be able to generate and publish my own website. Also the fact that there are a lot of themes at your fingertips is great, because you can also switch your aspect of your site without much effort.
