path-設置PATH時出錯，~/bashrc

設置PATH時出錯，~/bashrc

打開~/.bashrc，添加行：
export PATH=/home/rootliu/linuxc:$PATH

使生效

source .bashrc

之後：
bash: export: `/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/rootliu/linuxc': not a valid identifier
bash: lesspipe: No such file or directory
bash: dircolors: No such file or directory
bash: ls: No such file or directory
rootliu@ubuntu:~$ ls
bash: ls: No such file or directory

最佳回答：

把$PATH放前面，確保你的linuxc目錄存在！
