When invoked as sh, bash enters posix mode after the startup files are read.
. filename [arguments]
source filename [arguments]
Read and execute commands from filename in the current shell environment and return the exit status of the last command executed from filename. If
filename does not contain a slash, file names in PATH are used to find the directory containing filename. The file searched for in PATH need not be
executable. When bash is not in posix mode, the current directory is searched if no file is found in PATH. If the sourcepath option to the shopt
builtin command is turned off, the PATH is not searched. If any arguments are supplied, they become the positional parameters when filename is exe‐
cuted. Otherwise the positional parameters are unchanged. The return status is the status of the last command exited within the script (0 if no com‐
mands are executed), and false if filename is not found or cannot be read.
Большое спасибо за разъяснения!
Отмечу только, что поведение bash изменилось, что поломало работающие скрипты. Хотя понимаю, что они были криво написаны, но все равно неприятно.
