Manuale con pochi fronzoli e molto succo: tutto ciò che vi serve sapere su Linux...ATTENZIONE: SOLO PER ESPERTI!

ANTEPRIMA:

This is valid for all commands:
1 - The given commands can be rewritten on the command-line and easily pushing the
directions keys.
2 - Through the "history" command it's possible to see the given commands, if after it's
inserted the number, it shows the last n. commands given.
(es. history 14 ;shows last 14 commands)
3 - Often giving the commands, text files are created. To exiting from them, you need to press
"q" or, in case you want to stop the process because the execution of the command creates
nonsensical characters or doesn't accepted other input from keyboard, you need to press
"Ctrl+c".
4 - Often, commands given, provide a series of dates that pass the visualization of screen,
showing only a side of them. In order to obviate
this phenomenon, you can use an option "| more" or "| less" adding at the end of the command
(ls -la | more) or after the name of file:
(cat filename | more)
5 -moreover, after having used some procedures, you need to know that pushing the key
"Enter", continue the visualization for row and pushing key "Space" continue for page.
