macOS / OSX ansible path test

INFO

  • remote SSH shell on macOS does not use /etc/paths
  • this is not an issue of ansible, it is the way macOS processes config files on remote shells:
  • see ssh localhost echo \$PATH

ANSIBLE executes remote shell /bin/sh

  • ...if not specified otherwise and macOS does not read any startup files
  • example: [...]localhost '/bin/sh -c '"'"'sudo -H -S -n -u test /bin/sh -c '"'"'"'"'"[...]
  • even /bin/bash does not read any startup files by default
