  1. COP3502: Introduction to Computer Science Yashas Shankar

  2. Basic UNIX commands • SSH to shell.cs.fsu.edu • Reviews • ls – list • cp – copy • mv – move (rename) • rm – remove (delete) • pwd – gives current directory • man – gives manual • ‘>’ – redirection, create new file • ‘>>’ – redirection, append the file, create a file if it does not exist • Emacs – edit text • CTRL-X-S to save • CTRL-X-C to exit

  3. Basic UNIX commands • ls – list files and directory • Try ‘man ls’ to see how to use ls • ls –l  list details shankar@diablo:~/COP3502>ls -l total 24 - rw- --- --- 1 shankar CS-Grads 7 Aug 27 15:10 fileone.txt d rwx --- --- 2 shankar CS-Grads 4096 Aug 16 12:02 PROGRAMMING d rwx --- --- 2 shankar CS-Grads 4096 Aug 27 11:39 SLIDES d rwx --- --- 2 shankar CS-Grads 4096 Aug 17 11:08 WEBPAGE d = directory r = read w = write x = execute There are 3 groups of users -you -your group -others

  4. Basic UNIX commands • More on directories • .  your current directory • ..  one higher directory • ~  your home directory Shell.cs.fsu.edu higher directory shankar home directory COP3502 COPxxxx ppp2131.txt Assume that you are in ~/COP3502 Cd ..  move to your home directory Cd COPxxxx move to COPxxxx directory Cd ../COP3502 move to COP3502 directory

  5. Basic UNIX commands • More on directories • .  your current directory • ..  one higher directory • ~  your home directory Shell.cs.fsu.edu higher directory shankar home directory COP3502 COPxxxx b.txt a.txt a.txt a.txt Assume that you are in ~/COP3502 Cp a.txt ../COPxxxx/b.txt Cp a.txt ../COPxxxx mv ../COPxxxx/a.txt ../c.txt

  6. EXAMPLES Shell.cs.fsu.edu higher directory shankar home directory A C B COP3502_TEMP c.txt a.txt b.txt

  7. EXAMPLES Shell.cs.fsu.edu higher directory shankar home directory COP3502_TEMP A C B a.txt c.txt a.txt cp ~/COP3502_TEMP/C/c.txt ~/COP3503_TEMP/A/a.txt cp /home/grads/shankar/COP3502_TEMP/A/a.txt /home/grads/shankar/COP3502_TEMP/B

  8. EXAMPLES Shell.cs.fsu.edu higher directory shankar home directory COP3502_TEMP A a.txt a.txt cp A/a.txt . cp ~/COP3502_TEMP/A/a.txt . cp /home/grads/shankar/COP3502_TEMP/A/a.txt .

  9. Unix redirection • ‘>’ redirect output to a new file • An existing file will be deleted and created (overwrite) • ‘>>’ redirect output to a file • Append output to the end of the file if the file exists • Create a new file if the file does not exists

  10. How to use Emacs • Emacs filename  starts emacs • CTRL-X-S  save • CTRL-X-C  exit • CTRL-k  delete a line (after where the cursor is) • CTRL-y  paste the deleted line • CTRL-g  cancel • CTRL-x u  undo
