# This unit serves to initialise PROMPT_COMMAND as early as possible in cases
# where bash has been launched as a login shell. Though not an especially
# common practice, some profile.d drop-ins need to be able to extend its value.

# Setting PROMPT_COMMAND to an array isn't needed for scripts to add values to it
# but unfortunately some scripts like vte-2.91.sh checks it first if it's an
# array before usingn it as one.
