Linux Profile文件配置Jdk出了奇怪的问题...

Question

# /etc/profile

# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc

# It's NOT a good idea to change this file unless you know what you
# are doing. It's much better to create a custom.sh shell script in
# /etc/profile.d/ to make custom changes to your environment, as this
# will prevent the need for merging in future updates.

export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar  
export PATH=$PATH:$JAVA_HOME/bin 

在root账号下

 java 
-bash: /usr/jdk/jdk1.8.0_144/bin/java: Permission denied

尝试 source profile

[root@izbp1bhbv50pqcfhn3002ez etc]# source profile
-bash: $'\r': command not found

尝试java -version

[root@izbp1bhbv50pqcfhn3002ez etc]# source profile
-bash: $'\r': command not found

求解如何解决

楼主使用的是window版本的Cygwin控制的linux服务器吧
建议楼主换一个dos2unix
-bash: '\r': command not found是Cygwin问题
去下载一个dos2unix试一下，估计就好了
