# BASH | General commands

  
When running bash scripts, you can include other commands on the same line by using these at the end of each "line" command.   
  
bash:

```
A; B    # Run A and then B, regardless of success of A
A && B  # Run B if and only if A succeeded
A || B  # Run B if and only if A failed
A &     # Run A in background.
```

Example:   
`apt install vim -y A && B apt update vim -y`

Running a bash script file .sh:

```
sh scriptfilename.sh
```

If you get a "Permission denied" error, either run "sudo" or you may need to make the script executable by running

```
chmod +x scriptname.sh
```
