Bilah status layar untuk menampilkan direktori saat ini untuk zsh / bash shell

Saya sering menggunakan layar GNU dengan zsh sebagai shell saya. Ini akan menjadi fitur yang bagus (saya pikir) untuk dapat menampilkan nama direktori saat ini (bukan path lengkap) sebagai judul tab. Saya bisa melakukannya dengan CTRL+A SHIFT+Atetapi itu manual. Saya ingin mengubah setiap kali saya mengubah direktori.

Adakah yang tahu cara untuk melakukan ini?

Sunting: Jawabannya juga menampilkan solusi untuk bash.

Untuk zsh:

Letakkan ini di ~/.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 ~]$ 

Di Anda ~/.screenrc

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

Letakkan ini di ~/.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 (-).

Atau Anda cukup menempatkan ini sebagai judul shell Anda, jika Anda hanya perlu judul jendela yang akan ditampilkan sebagai direktori kerja saat ini.

Ini masuk ke Anda ~/.bashrc:

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

Ini masuk ke Anda ~/.screenrc: shelltitle '] | bash'
