unix users refer to the command line as the "shell" which is great

os x has a unix core which is also great

ps is a cooler version of force quit

i am now changing my terminal color settings to that of the oreilly books' suggestion.

you can set up specific profiles for the shell (with different bin directories, etc.)

alias = setup your own commands

.term files allow you to set up aliases and windows and stuff and save it for later use.

use command ~ to cycle through terminal windows

commands with ARGUMENTS - programs name with options or input

a directory is a place

pwd - print working directory

touch - creates an empty file

ls -R is a recursive listing of directories

less - used for reading text files

wildcards - * substitute any number of characters, ? substitute single character, [] specifies ranges between characters

three unix text editors - vi, emacs, and pico

mkdir - make a directory

cp copy file

gzip -v (verbose output)

chapter 5 @ 12:18

lpr prints

cat - reads files inputted on after the other

cat file(s) > output

>> appends

"To run a program in the background, add the & character at the end of the command line before you press the Return key. The shell then assigns and displays a process ID number for the program:

$ sort bigfile > bigfile.sort &
[1] 372
$:"

thinking about working in unix, i imagine sitting in a clean, well-lit bedroom in the afternoon, running specific jobs involving the maintence of my workstation.

ps - checks currently running processes

i.e.:

PID  TT  STAT      TIME COMMAND
  848  p1  S      0:00.02 -bash
  
  im only running bash (the command prompt)
  
ps using awk!:

"This is particularly long, so if you want to be fancy, you can add one more command to the pipe to just see the running commands: the awk filtering tool:

$ ps -aux | grep root | awk '{ print $1,$2,$11 }' | head
root 118 update
root 84 kextd
root 86 /usr/sbin/configd
root 87 /usr/sbin/diskarbitrationd
root 89 /usr/sbin/notifyd
root 116 netinfod
root 121 dynamic_pager
root 139 /System/Library/CoreServices/coreservi
root 161 /System/Library/CoreServices/SecurityS
root 172 /usr/sbin/distnoted
$"

top checks system resources

kill is like 'force quit' on crack and acid

super kill is 'kill - 9 PID'

x11 is os x's windowed unix interface.

openoffice can run in x11

fink - used to download unix programs for osx (i.e. pine - a text email client)

chmod +x makes a script executable
