how to use screen

the hierarchy of screen goes like this sessions > windows

You can create new sessions and put windows in it.

I am going to make an example of me working on two projects. These projects are my screen sessions.

For each project I want 3 windows -- vim window, a window to compile coffeescript and a window to run the server

My first project is a called cartoonmaker, and my second project is called musicmaker

I will first create a session for cartoonmaker

screen -S cartoonmaker

Now I have one window inside cartoonmaker

In this winodw I will compile my coffeescript coffee -cwb public/*.coffee

Now I want another window to run my server. I create a new window by Ctrl a+c

I will start my server via supervisor app.coffee

Now I want another window for vim. I Ctrl a+c agian. and then vi public/index.coffee

To toggle between windows in this session I can Ctrl a+n. Ctrl a+n is like alt tab in windows (kind of --see below).

To close a window I can either Ctrl d out of it or Ctrl K out of it

---

Now I want to detach from that session and create a new

To detach from the session I am in I Ctrl a+d

Now I am in my main bash.

I start a new session like last time screen -S musicmaker

I use Ctrl a+c to make new windows

I use Ctrl a+n to toggle between windows

I Ctrl a+d to detach again

To go back to a screen session, like cartoonmaker I screen -x cartoonmaker

to see a list of sessions to screen -ls

1870.cartoonmaker (05/01/11 03:44:24)
1870.musicmaker (05/01/11 03:42:21)

Here are some other helpful commands while you are in screen

all are prefixed with Ctrl a

• 0 through 9 – Switches between windows
• Ctrl n – Switches to the next available window
• Backspace – Switches to the previous available
• Ctrl a (again) – Switches back to the last window you were on
• Ctrl g - Toggles the visual bell. (wuff -- wuff)
• A – Changes window session name
• K – Kills a window session
• c – Creates a new window
• [ - Then use arrows to scroll up and down terminal
• C - Clear the screen
• " - nice ui for choosing windows
• ' - name of window ?

Δουλεύω σε περίπτερο και τα απογεύματα που δεν έχει πελάτες βαριέμαι πίσω από τον πάγκο. Δεν ήθελα να κοιτάω μόνο βίντεο οπότε έψαξα για κάτι διαφορετικό. Μπήκα στο chicken road. Αφού είναι από την Ελλάδα έχει εύκολες πληρωμές με κάρτα και τράπεζα. Δίνουν μπόνους στους καινούριους με έξτρα ποσό και μετά καθημερινές ανταμοιβές. Βάζουν και 25% cashback στο εβδομαδιαίο. Έπαιζα σε μικρά διαλείμματα και πήγαινε ομαλά. Δεν έχασα πολλά εκείνη τη μέρα.
