workspace_command process exited unexpectedly

Welcome

• Yes, I'm using the latest major release or the current development version. These are the only supported versions.
• Yes, I've searched similar issues and discussions on GitHub and didn't find any.

Current Behavior

I followed i3bar workspace buttons protocol and created a workspaces.sh with the first example, then called it using workspace_command. However, It throws an error whenever I try to switch to any workspace.

Expected Behavior

Pass the test of the re-create the default behaviour of i3bar:

#!/bin/sh
i3-msg -t subscribe -m '["workspace", "output"]' | {
    # Initially print the current workspaces before we receive any events. This
    # avoids having an empty bar when starting up.
    i3-msg -t get_workspaces;
    # Then, while we receive events, update the workspace information.
    while read; do i3-msg -t get_workspaces; done;
}

Reproduction Instructions

for c in $(i3-msg -t get_bar_config | python -c \
      'import json,sys;print("\n".join(json.load(sys.stdin)))'); do \
    (i3bar --bar_id=$c >i3bar.$c.log 2>&1) & \
  done;

Are you using a compositor?

I am sure I don't run any compositor

I don’t see a link to logs.i3wm.org. Did you follow https://i3wm.org/docs/debugging.html? (In case you actually provided a link to a logfile, please ignore me.)

workspace_command /path/to/your/workspaces.sh

Did you use the correct path to your script?

[qingbyin]

Yes, I did. My real bar config is :

bar {
  workspace_command ~/.config/i3/workspaces.sh
  i3bar_command i3bar --transparency
  status_command i3status-rs ~/.config/i3status-rust/config.toml
  position top
  tray_output primary
}

Try changing

#!/bin/sh

to

#!/bin/bash
