rhel4中装IC610环境变量设置后遇到问题

错误显示为：
bash: ./etc/bashrc: No such file or directory
bash-3.00$ su
但查看etc下有bashrc文件的啊，很郁闷,报警信息如下：
E325: ATTENTION
Found a swap file by the name ".bashrc.swp"
owned by: rootdated: Mon Aug 20 06:13:00 2012

NEWER than swap file！
(1) Another program may be editing the same file.
If this is the case, be careful not to end up with two
different instances of the same file when making changes.
Quit, or continue with caution.
(2) An edit session for this file crashed.
If this is the case, use ":recover" or "vim -r .bashrc"
to recover the changes (see ":help recovery").
If you did this already, delete the swap file ".bashrc.swp"
to avoid this message.
".bashrc" 19L, 611C
求助啊
