Modified Files: src/bin/sh: main.c parser.c parser.h sh.1 Log Message: PR standards/42829 Implement parameter and arithmetic expansion of $ENV before using it as the name of a file from which to read startup commands for the shell. This continues to happen for all interactive shells, and non-interactive shells for which the posix option is not set (-o posix). On any actual error, or if an attempt is made to use command substitution, then the value of ENV is used unchanged as the file name. The expansion complies with POSIX XCU 2.5.3, though that only requires parameter expansion - arithmetic expansion is an extension (but for us, it is much easier to do, than not to do, and it allows some weird stuff, if you're so inclined....) Note that there is no ~ expansion (use $HOME).
