基于欧拉openEuler 2203sp1的H3C Linux相关系统SDN/UIS/CAS/iMC正确设置alias和tab自动补全(bash_completion)的方法

系统自动屏蔽了vi/cp/rm等命令，并且按下TAB键后自动补全功能无法使用

第一步:

/usr/bin/vi ~/.bashrc
用#注释掉如下内容(Esc后i编辑)，然后Esc后:wq!保存退出

#if [[ "$0" == "-bash"  ]]; then
#alias rm='echo "-bash: rm: command not found"'
#alias rpm='echo "-bash: rpm: command not found"'
#alias which='echo "-bash: which: command not found"'
#alias grep='echo "-bash: grep: command not found"'
#alias mv='echo "-bash: mv: command not found"'
#alias vi='echo "-bash: vi: command not found"'
#alias vim='echo "-bash: vim: command not found"'
#alias ps='echo "-bash: ps: command not found"'
#alias top='echo "-bash: top: command not found"'
#alias bash='echo "-bash: bash: command not found"'
#alias sh='echo "-bash: sh: command not found"'
#alias find='echo "-bash: find: command not found"'
#alias yum='echo "-bash: yum: command not found"'
#alias dd='echo "-bash: dd: command not found"'
#alias chmod='echo "-bash: chmod: command not found"'
#fi

第二步: 

/usr/bin/vi ~/.inputrc

或者做完第一步后直接vi ~/.inputrc
on改为off，修改完成后，exit或logout重新登录即可使用tab自动补全功能。
