Could not execute command /usr/bin/bash


I am trying to show volume on my xmobar using the method here:

    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%"
            }

But instead of showing volume I get this message in my xmobar:

Could not execute command /usr/bin/bash

I tried replacing /usr/bin/bash with /bin/bash and just bash but with the same results

does anyone know what the problem is ?

When I run this in the terminal, it works fine:

$ bash ~/.config/xmobar/get-volume.sh 
Vol: 16%

output of $type bash is

bash is hashed (/usr/bin/bash)

Solution

  • A tilde is replaced with the appropriate directory by the calling shell (when that tilde is present in an unquoted context as part of the source code the shell is executing). There is no calling shell here, only a called one; and the tilde is data, not syntax.

    So change...

    "~/.config/xmobar/get-volume.sh"
    

    to:

    "/home/youraccount/.config/xmobar/get-volume.sh"
    

    ...or, to:

    "-c", ". ~/.config/xmobar/get-volume.sh"
    

    (which makes the argument following the -c be parsed as shell syntax, wherein a ~ is subject to replacement).
