# Bash

Bash is a classic and should always be understood.  After all, it  was  the first shell that you used so there's a bit of nostalgia surrounding it. 


- `touch` creates the file named `zk_sync` and `chmod +x` makes the file an executable file, but we still need to say what shell will execute this file, and what exactly are the commands to be executed.
- [ bash command](https://discussions.apple.com/thread/252176464) for Big Sur if you ever decide to upgrade
- the  oh-my-zsh version  of bash  is now regularly maintained through a git repo called [Bash-It](https://github.com/Bash-it/bash-it)
- check the file size of something in your directory by ```wc -c /Users/shwethajayaraj/qisket/file```
	- you can further turn it into a bash variable by doing: 
	-  ```myfilesize=$(wc -c "/etc/passwd" | awk '{print $1}')
            printf "%d\n" $myfilesize
            echo "$myfilesize"```
