Some useful everyday linux commands

11/7/20152 min read

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 run two tasks in parallel, the first tasks gets backgrounded

top

  •   Provides a real time summary of the processes running on your system.
    
  •   Can be used to see what's chewing up memory
    

Ctrl + R

  •   Reverse search through your bash command history
    

sudo

  • run command as the superuser

sudo -u [user]

  • run command as a different user

sudo !!

  • run the last command as super user

vi [file]

  •   edit the file with vi text editor
