Bildschirmstatusleiste zur Anzeige des aktuellen Verzeichnisses für die zsh / bash-Shell

Ich benutze GNU-Bildschirm oft mit zsh als Shell. Es wäre eine nette Funktion (denke ich), den aktuellen Verzeichnisnamen (nicht den vollständigen Pfad) als Tabulatortitel anzeigen zu können. Ich kann das damit machen, CTRL+A SHIFT+Aaber das ist manuell. Ich möchte, dass es sich ändert, wenn ich das Verzeichnis wechsle.

Kennt jemand einen Weg, dies zu tun?

Bearbeiten: Die Antwort enthält auch die Lösung für Bash.

Für zsh:

Setzen Sie dies in Ihre ~/.zsh

[centos@centos ~]$ cat .zsh
if [[ ${TERM} == "screen-bce" || ${TERM} == "screen" ]]; then
  precmd () { print -Pn "\033k\033\134\033k%m[%1d]\033\134" }
  preexec () { print -Pn "\033k\033\134\033k%m[$1]\033\134" }
else
  precmd () { print -Pn "\e]0;%n@%m: %~\a" }
  preexec () { print -Pn "\e]0;%n@%m: $1\a" }
fi
PS1=$'%{\e[0;32m%}%m%{\e[0m%}:%~> '
export PS1
[centos@centos ~]$ 

In deinem ~/.screenrc

hardstatus string "%h"
caption always "%{= kw} %-w%{= wk}%n*%t%{-}%+w%{= kw} %=%d %M %0c %{g}%H%{-}"

Setzen Sie dies in Ihre ~/.screenrc

caption always "%m/%d/%y %0c%{=b kg}  %l  %{=r gk}%-w%{=b wb}%50>%n%f* %t%{-}%+Lw%<%{- Wk}"

caption always "%m/%d/%y %0c%{=b kg}  %l  %{=r gk}%-w%{=b wb}%50>%n%f* %t%{-}%+Lw%<%{- Wk}"

# caption description:
# caption always "%?%F%{-b bc}%:%{-b bb}%?%C|%D|%M %d|%H%?%F%{+u wb}%? %L=%-Lw%45>%{+b by}%n%f* %t%{-}%+Lw%-0<"
# 
# Anything I don't describe is treated literally.
# 
# %?          - Start of a conditional statement.
#  %F         - Use this part of the statement if the window has focus (i.e. it
#               is the only window or the currently active one).
#  %{-b bc}   - Turn off bold, blue foreground, cyan background.
# %:          - else
#  %{-b bb}   - Turn off bold, blue foreground, blue background (this obscures
#               the text on non-focused windows and just gives a blue line).
# %?          - End conditional statement.
#  %C         - time (hh:mm, leading space) in 12 hour format
#  %D         - Three-letter day-of-week appreviation
#  %M         - Three-letter month appreviation
#  %d         - Day of the month
#  %H         - hostname
#  %?         - Start of conditional statement.
#   %F        - Use this part of the statement if the window has focus.
#   %{+u wb}  - underlined, white foreground, blue background
#  %?         - End conditional (if not focused, text remaind blue on blue).
#    %L=      - truncation/padding point.  With the 'L' qualifier, basically
#               just acts as a reference point.  Further truncation/padding is
#               done relative to here, not the beginning of the string
#    %-Lw     - window list up to but not including the current window (-),
#               show window flags (L)
#    %45>     - truncation/padding marker; place this point about 45% of the

#               way into the display area (45)
#    %{+b by} - add bold (still underlined from before), blue foreground,
#               yellow background
#      %n     - number of the current window
#      %f     - flags for current window
#      %t     - title of current window
#    %{-}     - undo last color change (so now we're back to underlined white
#               on blue)  (technically, this is a pop; a second invocation
#               would drop things back to unadorned blue on cyan)
#    %+Lw     - window list from the next window on (-), show window flags (L)
#    %-0<     - truncation/padding point.  Place this point zero spaces (0)
#               from the right margin (-).

Sie können dies auch einfach als Shell-Titel festlegen, wenn nur der Titel des Fensters als aktuelles Arbeitsverzeichnis angezeigt werden soll.

Dies geht in Ihre ~/.bashrc:

PROMPT_COMMAND='echo -ne "\033k\033\0134\033k${HOSTNAME}[`basename ${PWD}`]\033\0134"'`

Dies geht in Ihre ~/.screenrc: shelltitle '] | bash'
