有没有哪个命令找出变量是在哪个文件中设置的？

在hp-ux当中，有一个变量在/etc/profile当中已经改为一个新值，重新登录root用户已经生效，普通用户还是老的值，怀疑在别的文件还有设置，用户目录下的.profile和.dtprofile都找不到。
太怪了！！

Terminal登录，新值生效，CDE登录是老的值

如果确实是bsh的话，那应该就是$HOME/.profile的问题，可以多加几步显示查找一下原因。

在/etc/dt/xconfig/Xsession.d/目录当中，有一个控制文件，隐藏的够深的，只要在这个目录中设置参数文件，CDE登录就起作用了

3.25) I'm having a problem in which that /etc/profile doesn't seem to be
      read when login in on the CDE environment. I put a few environment
      stuff in there (path and others) but nothing seems to be set. I know
      about $HOME/.dtprofile and DTSOURCEPROFILE=true but that doesn't help
      for /etc/profile.  Is there as /etc/profile.dt that should exist or a
      similar file for CDE?

Xsession can source a user's traditional HomeDir/.profile or .login script.
By default this capability is disabled.  To tell the Xsession to source the
.profile or the .login script, we set the DTSOURCEPROFILE to true.

To change the DTSOURCEPROFILE for all users or other variables for all
users, create an /etc/dt/config/Xsession.d script that sets the new values.
For example create an executable ksh script, /etc/dt/config/Xsession.d/test
containing export MYVAR="value".  This should work in place of
/etc/profile.
