<html> <head> <style></style> </head> <body class='hmmessage'> Dear all, According to instructions_for_linux_installer.txt,If you are running the bash shell then you would look for an entry in the .profile file something like: export PATH=/usr/local/bin:/usr/esru/bin:/usr/esru/esp-r/bin:/home/fred/bin:$PATH   But I don't know how to edit it.File /etc/profile is as follows:   # /etc/profile: system-wide .profile file for the Bourne shell (sh(1)) # and Bourne compatible shells (bash(1), ksh(1), ash(1), ...). if [ -d /etc/profile.d ]; then   for i in /etc/profile.d/*.sh; do     if [ -r $i ]; then       . $i     fi   done   unset i fi if [ "$PS1" ]; then   if [ "$BASH" ]; then     PS1='\u@\h:\w\$ '     if [ -f /etc/bash.bashrc ]; then  . /etc/bash.bashrc     fi   else     if [ "`id -u`" -eq 0 ]; then       PS1='# '     else       PS1='$ '     fi   fi fi umask 022   I try to add  export PATH=/usr/local/bin:/usr/esru/bin:/usr/esru/esp-r/bin:/home/fred/bin:$PATH  at the end of file profile.But it didn't work after I restarted Ubuntu.Look forward to your answers.Grateful thanks! <hr />使用Messenger保护盾2.0，支持多账号登录！ <a href='http://www.windowslive.cn/safe/' target='_new'>现在就下载！</a></body> </html>
