This page lists the commands that you should be practicing. I will do my best to keep this list updated as we go through things in class.

Connecting

ssh - connect to remove server
- ssh username@server_address
- E.g., ssh yourusername@eos01.cis.gvsu.edu

Getting files/directories

wget <URL> - gets a file from a remote URL
git clone <REPO> - clones a git repository
- Note - typically you’ll want to use the SSH version for repositories YOU’ll be updating and the HTTP version for repositories you just want to play with

ls - List files
- E.g., ls ~, ls ., ls CIS241
cd - Change directory
- E.g., cd ~, cd .., cd /WEB_STUDENT/yourusername
touch filename - Create empty file
rm - Remove – BE CAREFUL - THERE IS NO RECYCLE BIN AND ANYTHING DELETED CANNOT BE RECOVERED
- E.g., rm filename - deletes filename
- rm -rf directory - removes the directory AND everything inside of it
rmdir - Remove directory
- E.g., rmdir directory - note, directory must be empty for this to work (the rm -rf command takes care of the deletion if not)
mv f1 f2 - Cut and paste or rename - f1 is the original file/directory and f2 is the new name of the file/directory
- Examples (assuming we have ~/file1, ~/file2, ~/dir1, ~/dir1/dir2
  - mv file1 file2 (renames file1 to file2)
  - mv ~/file1 ~/dir1/my_new_file (moves and renames file1 to be my_new_file within dir1)
  - mv dir1 my_new_dir (renames dir1 to be my_new_dir)
cp f1 f2 - Copy and paste (same concept as mv, but creates a copy)
- Examples (assuming we have ~/file1, ~/file2, ~/dir1, ~/dir1/dir2
  - cp file1 new_file (copies file1 to new_file)
  - cp -r dir1 newdir (recursively copies dir1 to newdir - meaning all the contents of dir1 are also now in newdir)
tree - shows a tree-based graphical representation of your current working directory and its children
- tree <path> - same, but for the <path> provided
pwd - tells you where you are at in the filesystem

nano <filename> - edit a file with the nano editor
- ^ in the bottom menu represents Ctrl (or Cmd if you’re on Mac)

command1 | command2
- Send output of command1 into command2
command1 > file
- Send output of command into a new file: file
command1 > file 2> file.err
- Send output of command into a new file (file) and error into a new file (file.err)

Worth checking the man pages for parameters!
