Week 1 notes

Concepts

Permissions - all files have unique permissions that control access, ls -la will reveal all your file permissions in your current working directory.

Mount Points - There are no drive letters in Unix, all additional file systems are added to one big tree. New file systems are attached to directories.

Common commands

The basics

• exit : exit current shell
• ls : list files
• cp : copy files
• mv : move files
• rm : remove files
• cd : change working directory
• pwd : print working directory
• mkdir : make directory
• rmdir : remove directory
• man : view manual page, used man command example: man passwd
• apropos : search through manual pages for text
• passwd : change passwd
• vi, emacs, pico : text editors
• chmod : change permissions on a file

Assorted cruft.

• cat > filename - Allows you to create a text file 1 line at a time. More later.
• [control] [d] - sends an end of file.
• [shift] [page up] or [shift] [page down] - will scroll your screen up or down
• [control] [c] - stops the currently running program

One particularly interesting point is DOS/Win to Linux HOWTO

I didn't mention this in class but there is a good ssh(faster than java) client for Windows called PuTTY
