使用screen非常簡易.只需在SHELL鍵入screen,便可打開一個screen session。
而在每個screen session 下，所有命令都以 ctrl+a(C-a) 開始。
現在讓我來簡單介紹基本的命令
C-a c -> Create == 開啟新的 window
C-a n -> Next == 切換到下個 window
C-a p -> Previous == 前一個 window
C-a C-a -> Other == 在兩個 window 間切換
C-a w -> Windows == 列出已開啟的 windows 有那些
C-a 0 -> 切換到第 0 個 window
C-a 1..9 -> 切換到第 1..9 個window
C-a a -> 發出 C-a，在 emacs, ve, bash, tcsh 下可移到行首
C-a t -> Time，顯示當前時間，和系統的 load
C-a K(大寫) -> kill window，強行關閉當前的 window
C-a [ -> 進入 copy mode，在 copy mode 下可以回滾、搜索、複製就像用使用 vi 一樣
C-b Backward，PageUp
C-f Forward，PageDown
H(大寫) High，將游標移至左上角
L Low，將游標移至左下角
0 移到行首
$ 行末
w forward one word，以字為單位往前移
b backward one word，以字為單位往後移
Space 第一次按為標記區起點，第二次按為終點
Esc 結束 copy mode
C-a ] -> Paste，把剛剛在 copy mode 選定的內容貼上
C-a ? -> Help，顯示簡單說明
C-a d -> detach，將目前的 screen session (可能含有多個 windows)
丟到後臺執行當按了 C-a d 把 screen session detach 掉後，會回到還沒進 screen 時的狀態，此時在 screen session 裏每個 window 內運行的 process (無論是前臺/後臺)都在繼續執行，即使 logout 也不影響。下次 login 進來時:screen -ls -> 顯示所有的 screen sessions
screen -r [keyword] -> 選擇一個screen session 恢復對話若 screen -ls 裏有 Attached sessions:
screen -d [keyword] -> 強制 detach，以便「接手」過來
