There is a bug in sh-4.0 source command:
Must specify directory (./file) for filename, without not work.
sh-4.0# cd /tmp
sh-4.0# echo aaa=ppp > sourcefile
sh-4.0# ls -l sourcefile
-rw-r--r-- 1 root root 8 3 ago 20:37 sourcefile
sh-4.0# cat sourcefile
aaa=ppp
sh-4.0# . sourcefile
sh: .: sourcefile: file not found
sh-4.0# source sourcefile
sh: source: sourcefile: file not found
sh-4.0# echo $aaa
sh-4.0# source ./sourcefile
sh-4.0# echo $aaa
ppp
sh-4.0# exit
hope this help.
