I do much of my work from tmux, I love it so much that I want to setup some
functionality that puts me in tmux even if I didn't ask for it.

## Bash Function

Bash function to check if the shell is in a tmux session.

``` bash
in_tmux () {
 if [ -n "$TMUX" ]; then
 return 0
 else
 return 1
 fi
 }
```

## Using the bash function

I often open up vim to do some quite edits, but before I know it I have several
splits open and I need access to another shell utility, but I forgot to start
in tmux. This function makes sure tht I start in tmux everytime.

Using `if_tmux` to ensure vim is opened in tmux.

``` bash
vim () {
 in_tmux \
 && nvim \
 || bash -c "\
 tmux new-session -d;\
 tmux send-keys nvim Space +GFiles C-m;\
 tmux -2 attach-session -d;
 "
 }
```

I am not quite sure if this is proper use of the `&&` and `||`, let me know if
you have a better way to do one thing if `in_tmux` returns true and another if
it returns faslse.
