8 Editing files with SciTE Different ways to open a file File Open Drag and drop the file to an already open SciTE. Dragging the file to the SciTE icon. Typing in the terminal (recommended): scite file-name.p

9 Compiling After saving the file. Different ways: Typing in the terminal: pick file-name.p En SciTE: Tools Compile. En SciTE: click in the hammer button in the Tool bar.

10 Basic commands man: asking the system for help about something. man cp apropos: find about something in the man pages. apropos copy

11 Basic commands pwd: print the working directory (the one currently being used). cd: change the working directory. cd mydir1 ls: list the contents of a directory ls mydir1 ls -l

12 Basic commands mkdir: create directories mkdir midir2 cp: copy files. cp fich1 fich2 cp fich1 fich2 midir1 mv: move files. mv fich1 fich2 mv fich2 fich3 midir1

13 rm: delete files (BE CAREFUL!). rm fich1 fich2 rm -r midir1 CAREFUL cat: see the contents of files. cat fich4 cat fich4 fich5

14 Paths Absolute path: string of directories starting from the root separated by slashes. Always starts with slash (root). /home/al-09-10/juan/file.txt Relative path: string of directories starting with the working directory. al-09-10/juan/file.txt.. : father directory.../juan/file.txt. : current directory../file.txt

15 Executable files./ to tell the system that it is in the current directory../myprogram or the absolute path: /home/al-09-10/juan/myprogram You can add the current directory to the places where executables are searched (default configuration in the lab): export PATH=.:$PATH

16 Command line tricks to repeat already executed commands. Tab to complete names Ctrl+r to search in the already executed commands.

17 Copy files Windows: Install this app: Winscp MacOSX In Finder: Ir Conect to server In the command line: scp Linux In the file explorer: Lugares Conectar con servidor (seleccionar SSH) In the command line: scp

18 Remote console Windows: Install this app: Putty MacOSX In the command line: ssh Linux In the command line: ssh

19 Example with scp Copy a file from a remote server to the local machine (for example, from the lab to my home terminal): scp your-login@servidor:origin-filename destitnation-filename Examples: scp juan@zeta01.aulas.gsyc.es:expr.p expr.p (copies the file expr.p from juan s home directory to the working directory in juan s PC) scp juan@zeta22.aulas.gsyc.es:desktop/a.txt a.txt (copy the file a.txt from juan s Desktop directory in the server to the local directory in his PC)

20 Example with scp Copy a file from the local machine to a remote server (for example, from my home terminal to the lab): scp origin-filename your-login@servidor:destination-filename Example: scp a.txt juan@zeta22.aulas.gsyc.es:desktop/a.txt (copy the file a.txt from the local directory in his PC to juan s Desktop directory in the server)
