status.sh무엇이라고 불리는가 ~/.config/sway/config:

# The Sway configuration file in ~/.config/sway/config calls this script.
# You should see changes to the status bar after saving this script.
# If not, do "killall swaybar" and $mod+Shift+c to reload the configuration.

# The abbreviated weekday (e.g., "Sat"), followed by the ISO-formatted date

# time and date.
date_formatted=$(date "+%a %F %H:%M")

# "upower --enumerate | grep 'BAT'" gets the battery name (e.g.,
# "/org/freedesktop/UPower/devices/battery_BAT0") from all power devices.
# "upower --show-info" prints battery information from which we get
# the state (such as "charging" or "fully-charged") and the battery's
# charge percentage. With awk, we cut away the column containing
# identifiers. i3 and sway convert the newline between battery state and
# the charge percentage automatically to a space, producing a result like
# "charging 59%" or "fully-charged 100%".
battery_info=$(upower --show-info $(upower --enumerate |\
grep 'BAT') |\
egrep "state|percentage" |\
awk '{print $2}')

# "amixer -M" gets the mapped volume for evaluating the percentage which
# is more natural to the human ear according to "man amixer".
# Column number 4 contains the current volume percentage in brackets, e.g.,
# "[36%]". Column number 6 is "[off]" or "[on]" depending on whether sound
# is muted or not.
# "tr -d []" removes brackets around the volume.

나는 bash를 좋아하지만 이를 위해 Python 스크립트를 사용합니다. Python의 표준 라이브러리에는 이런 종류의 작업을 위한 많은 유틸리티가 있는 것 같습니다.

from datetime import datetime
from psutil import disk_usage, sensors_battery
from psutil._common import bytes2human
from socket import gethostname, gethostbyname
from subprocess import check_output
from sys import stdout
from time import sleep

def write(data):
    stdout.write('%s\n' % data)
    stdout.flush()

def refresh():
    disk = bytes2human(disk_usage('/').free)
    ip = gethostbyname(gethostname())
    try:
        ssid = check_output("iwgetid -r", shell=True).strip().decode("utf-8")
        ssid = "(%s)" % ssid
    except Exception:
        ssid = "None"
    battery = int(sensors_battery().percent)
    status = "Charging" if sensors_battery().power_plugged else "Discharging"
    date = datetime.now().strftime('%h %d %A %H:%M')
    format = "Space: %s | Internet: %s %s | Battery: %s%% %s | Date: %s"
    write(format % (disk, ip, ssid, battery, status, date))

while True:
    refresh()
    sleep(1)

다음은 바의 스크린샷입니다.

가벼우면서도 기능이 풍부한 상태 표시줄을 작성했습니다.스윙 상태i3와 스웨이용입니다.

특히 Bash 스크립트처럼 매 순간 새로운 프로세스가 생성되는 것을 피하기 위해 가능한 한 가볍게 만들기 위해 전적으로 C/C++로 작성되었습니다.
