[obregonia1]

Describe the bug Some commands behave strangely.

$ bat .tool-versions
[bat error]: Could not parse pager command.

$ echo $PAGER
bat"

To see a list of supported npm commands, run:
  npm help:/Users/kentaro/.yarn/bin:/Users/kentaro/bin:/Users/kentaro/.yarn/bin

To Reproduce

# environment
Apple M1 Pro
maxOs: 13.6（22G120）

$ brew install rtx

# .zshrc
...
export PAGER='bat'
...
eval "$(/opt/homebrew/bin/rtx activate zsh)"

bat works correctly after comment out eval "$(/opt/homebrew/bin/rtx activate zsh)" and $ source .zshrc

Expected behavior bat works correctly
