有谁可以讲一下 PATH的设置问题？？？

lgreat

在root下PATH是/usr/bin:/usr/sbin；要给path中添加一些路径，可是在\r\n\r\n/etc/profile中添加后是在普通用户下起作用，在root下不变。\r\n\r\n在root下怎么设置呢？

dradhzn

cp /etc/skel/local.profile ~/.profile \r\nthen edit ~/.profile

dradhzn

login and logout again .

是 boure shell ，系统都重起过一次啊

dradhzn

i don\'t believe it , let\'s try it \r\nmake sure your are root user , \r\n#id\r\n#cd /tmp\r\ncreate a file name as try.sh contains following \r\n\r\n#!/bin/sh\r\ncd /tmp\r\nls * >; /tmp/try.log\r\n \r\n#chmod a+x /tmp/try.sh\r\n\r\nmake sure .profile present at your home directroy ~/ \r\nmake sure .profile contains path line like following . \r\n\r\nPATH=/usr/bin:/usr/sbin:/tmp\r\n\r\n#sh \r\n#try.sh \r\ncheck try.log in /tmp/ , it should be there...

哦，直接用root用户登录，好像对了，\r\n\r\n但是我用普通用户登录后su 到root 不行吗？

dradhzn

paste your result \r\n# grep root /etc/passwd \r\nas root user \r\n# cat ~/.profile

dradhzn

moreover, \r\nwhat is your su command ?  \r\n# su root   \r\nor \r\n#su - root \r\nPS.  if you want root env , have to use \"su - root \" \r\nand , next time please please remember paste all you command you have tried . else people might feel they are fooled .

我直接用的su \r\n\r\n好了，谢谢各位！
