Some useful everyday linux commands

I decided to write down a list of every day commands that I use in the the Bash command line in Linux. This is by no means a definitive list and it will grow as I remember or come across commands that make my life easier

ls

  list information about files in the directory

ls -la

  list information about files in the directory

```
  *-l* means long listing format
```

  *-a* means list all files including ones that start with .

cd [directory]

  change directory to the specified directory

ps

```
  snapshot of the current processes
```

ps -ef

```
  *-e* select all processes
```
```
  *-f* full format listing
```

ps -ef | grep [processname]

  grep for the details of a specific process

alias (usually used in the bash profile to be persisted)

ll -> ls -la
Aliases for shortcuts to frequently visited directories
Aliases to bash scripts I've written to automate things like sync'ing a github pages branch with master and pushing to the cloud

source [filename]

  source is a bash shell built-in command that executes the content of the file passed as argument, in the current shell. It has a synonym in '.' (period).

source ~/.bash_profile

  this has the effect of reloading the bash_profile so you don't have to kill & open the terminal to see changes

&&

  used for tying consecutive commands together

```
  example *$ cd Documents && ls -la*
```

&

  Can be used to see what's chewing up memory

sudo

sudo -u [user]

run command as a different user

sudo !!

run the last command as super user

vi [file]

```

```
