在启动cygwin,会显示
-bash: $'\r': command not found
-bash: $'\r': command not found
-bash: $'\r': command not found
-bash: $'\r': command not found
-bash: $'\r': command not found
-bash: $'\r': command not found
-bash: $'\r': command not found
-bash: /home/lenovo/.bash_profile: line 47: syntax error: unexpected end of file
解决方法:在cygwin中输入:dos2unix -n .bash_profile .bash_profile
关闭重新打开cygwin,ok了。所以再一次提醒,不要用window里的记事本或者写字本打开修改,使用UltraEdit不要转化格式,因为在window下和linux中回车符是不相同的。
