无法执行命令 /usr/bin/bash
Could not execute command /usr/bin/bash
我正在尝试使用 here:
方法在我的 xmobar 上显示音量
Config { font = "xft:Ubuntu Mono:pixelsize=16:antialias=true:hinting=true"
, borderColor = "black"
, border = TopB
, bgColor = "black"
, fgColor = "grey"
, position = TopP 0 0
, commands = [
Run Date "%a %_d.%_m %H:%M" "date" 10
, Run StdinReader
, Run Com "/usr/bin/bash" ["-c", "~/.config/xmobar/get-volume.sh"] "myvolume" 1
]
, sepChar = "%"
, alignSep = "}{"
, template = "<fc=#FFF>%StdinReader%</fc>}{<fc=#FFF>%date%</fc> -- %myvolume%"
}
但我没有显示音量，而是在我的 xmobar 中收到此消息：
Could not execute command /usr/bin/bash
我尝试用 /bin/bash 和 bash 替换 /usr/bin/bash 但结果相同
有人知道问题出在哪里吗？
当我在终端中 运行 时，它工作正常：
$ bash ~/.config/xmobar/get-volume.sh
Vol: 16%
$type bash 的输出是
bash is hashed (/usr/bin/bash)
grep -3i execv sux 之后 strace -s <PID> -fp -o sux
的结果

波浪号通过调用 shell 替换为适当的目录（当波浪号作为源代码的一部分出现在未引用的上下文中时，shell 正在执行）。这里没有调用shell，只有一个被调用；波浪号是数据，不是语法。
所以改变...
"~/.config/xmobar/get-volume.sh"
至：
"/home/youraccount/.config/xmobar/get-volume.sh"
...或，至：
"-c", ". ~/.config/xmobar/get-volume.sh"
（这使得 -c 之后的参数被解析为 shell 语法，其中 ~ 需要替换）。
我正在尝试使用 here:
方法在我的 xmobar 上显示音量 Config { font = "xft:Ubuntu Mono:pixelsize=16:antialias=true:hinting=true"
, borderColor = "black"
, border = TopB
, bgColor = "black"
, fgColor = "grey"
, position = TopP 0 0
, commands = [
Run Date "%a %_d.%_m %H:%M" "date" 10
, Run StdinReader
, Run Com "/usr/bin/bash" ["-c", "~/.config/xmobar/get-volume.sh"] "myvolume" 1
]
, sepChar = "%"
, alignSep = "}{"
, template = "<fc=#FFF>%StdinReader%</fc>}{<fc=#FFF>%date%</fc> -- %myvolume%"
}
但我没有显示音量，而是在我的 xmobar 中收到此消息：
Could not execute command /usr/bin/bash
我尝试用 /bin/bash 和 bash 替换 /usr/bin/bash 但结果相同
有人知道问题出在哪里吗？
当我在终端中 运行 时，它工作正常：
$ bash ~/.config/xmobar/get-volume.sh
Vol: 16%
$type bash 的输出是
bash is hashed (/usr/bin/bash)
grep -3i execv sux 之后 strace -s <PID> -fp -o sux

波浪号通过调用 shell 替换为适当的目录（当波浪号作为源代码的一部分出现在未引用的上下文中时，shell 正在执行）。这里没有调用shell，只有一个被调用；波浪号是数据，不是语法。
所以改变...
"~/.config/xmobar/get-volume.sh"
至：
"/home/youraccount/.config/xmobar/get-volume.sh"
...或，至：
"-c", ". ~/.config/xmobar/get-volume.sh"
（这使得 -c 之后的参数被解析为 shell 语法，其中 ~ 需要替换）。
