已经明白为什么interactive login shell是按照那样的顺序去读取初始化文件了,下面是bash源码中的一段: sourced_login = 0;
/* A shell begun with the --login (or -l) flag that is not in posix mode[color="Red"]//这段注释没有看懂是什么意思,下面的都是根据其他信息
runs the login shell startup files, no matter whether or not it is [color="Red"]来判断的
interactive. If NON_INTERACTIVE_LOGIN_SHELLS is defined, run the
startup files if argv[0][0] == '-' as well. */
#if defined (NON_INTERACTIVE_LOGIN_SHELLS)
if (login_shell && posixly_correct == 0)
#else
if (login_shell < 0 && posixly_correct == 0)
#endif
{
[color="urple"] /* We don't execute .bashrc for login shells. */
no_rc++;
/* Execute /etc/profile and one of the personal login shell
initialization files. */
[color="Red"]if (no_profile == 0)
{
maybe_execute_file (SYS_PROFILE, 1);
if (act_like_sh) /* sh */
maybe_execute_file ("~/.profile", 1);
else if ((maybe_execute_file ("~/.bash_profile", 1) == 0) &&
(maybe_execute_file ("~/.bash_login", 1) == 0)) /* bash */
maybe_execute_file ("~/.profile", 1);
}
sourced_login = 1;
