  • cd, pwd
  
  
  
  

3. File Information and Content

• Using ls to list files (like DOS dir)

  • set, env, echo
  
  
  
  


• Exporting variables to child processes


• Shell Command Line Interpretation


• Order and sequence of command line components


• Using FNG characters and their consequences


• Three kinds of quoting
  
  
  
  • \, ', "
  
  
  
  


• Variable substitution

8. File access permissions

• UNIX file security


• Three access categories and permission modes

• Using pipes to connect processes via I/O


• Enhanced text display commands
  
  
  
  • less, pg
  
  
  
  

10. Using the vi Editor

• Command, input, and line editor modes


• Setting terminal type

• Copying, cutting, and pasting text


• Searching and replacing text


• File operations using ex


• Customizing your vi session
  
  
  
  • .exrc
  
  
  
  


• Recommended configuration options and actions

11. Customizing Your Login Session

• System and user configuration files


• Setting and exporting common environment variables


• Interpreting and setting the PATH variable


• Command line aliases


• Display and set terminal characteristics
  
  
  
  • stty
  
  
  
  


• Other recommended setup commands

12. Printing

• lpr, lpq, lprm, lpc status


• Comparing BSD and SVR4 print utilities


• Printing files


• Query the Print Queue


• Canceling a print request

13. File Search and Packaging

• Locating files in a subtree


• find


• Search for text in files
  
  
  
  • grep
  
  
  
  


• Compress and uncompress files
  
  
  
  • compress
  
  
  
  


• Create file archives
  
  
  
  • tar
  
  
  
  

14. Network Utilities

• Test for host access
  
  
  
  • PING
  
  
  
  


• Write and talk


• Controlling communication access
  
  
  
  • mesg
  
  
  
  


• Command line Email
  
  
  
  • mail
  
  
  
  


• Determining defined network hosts names and addresses


• Logging into a remote host
  
  
  
  • telnet
  
  
  
  


• Transferring files between hosts
  
  
  
  • ftp
