[20150427]tmux与INPUTRC定义冲突.txt
--我前一阵子发现在tmux里面一些按键与INPUTRC冲突.
我的/etc/inputrc定义如下:
"\e[1~": beginning-of-line # home
"\e[2~": yank-last-arg # insert
"\e[3~": delete-char # delete
"\e[4~": end-of-line # end
"\e[5~": backward-kill-word # page up
"\e[6~": kill-word # page down
#set bell-style visible
set bell-style none
set meta-flag On
set convert-meta Off
set input-meta on
set output-meta On
set horizontal-scroll-mode On
set show-all-if-ambiguous On
# (F1 .. F5) are "\e[[A" ... "\e[[E"
#"\e[[B": "select * from v$system_event ;" # F2
"\e[[A": backward-word # F1
"\e[[B": forward-word # F2
"\e[[C": backward-kill-line # F3
"\e[[D": kill-line # F4
"\e[[E": yank # F5
"\e[17~": undo # F6
"\e[18~": history-search-forward # F7
"\e[19~": history-search-backward # F8
"\e[20~": character-search # F9
"\e[21~": character-search-backward # F10
"\e[23~": "\eb'\ef'" # F11
"\e[24~": kill-whole-line # F12
"\e[5C": forward-word
"\e[5D": backward-word
"\e[1;5C": forward-word
"\e[1;5D": backward-word
--不过我发现在tmux下无法使用F1,F2,F3,F4.

--才发现进入TERM不再是linux,而是变成了screen.这样一些按键的定义被重新修改.
--对比发现:
# infocmp screen linux | grep kf[123456]:
kf1: '\EOP', '\E[[A'.
kf2: '\EOQ', '\E[[B'.
kf3: '\EOR', '\E[[C'.
kf4: '\EOS', '\E[[D'.
kf5: '\E[15~', '\E[[E'.
--可以发现F1,F2,F3,F4,F5的定义与原来不一致,这样导致无法使用.为此我建立新的inputrc文件.内容如下:
# cat /etc/tmux.inputrc
"\e[1~": beginning-of-line # home
"\e[2~": yank-last-arg # insert
"\e[3~": delete-char # delete
"\e[4~": end-of-line # end
"\e[5~": backward-kill-word # page up
"\e[6~": kill-word # page down
#set bell-style visible
set bell-style none
set meta-flag On
set convert-meta Off
set input-meta on
set output-meta On
set horizontal-scroll-mode On
set show-all-if-ambiguous On
# (F1 .. F5) are "\e[[A" ... "\e[[E"
#"\e[[B": "select * from v$system_event ;" # F2
"\eOP": backward-word # F1
"\eOQ": forward-word # F2
"\eOR": backward-kill-line # F3
"\eOS": kill-line # F4
"\e[15~": yank # F5
"\e[17~": undo # F6
"\e[18~": history-search-forward # F7
"\e[19~": history-search-backward # F8
"\e[20~": character-search # F9
"\e[21~": character-search-backward # F10
"\e[23~": "\eb'\ef'" # F11
"\e[24~": kill-whole-line # F12
--如何显示进入tmux是指定INPUTRC=/etc/tmux.inputrc呢? 很简单,修改.bashrc文件加入如下:
if [[ '' = "$TMUX" ]]
then
export INPUTRC=/etc/inputrc
else
export INPUTRC=/etc/tmux.inputrc
fi
--这样就可以正常实现功能键在两种模式下正常使用了.
