oracle帐号永久生效 [Linux] alias永久生效

[root@oracle6 ~]# alias dfk='df | awk -f /usr/bin/dfb'

[root@oracle6 ~]# alias dfg='df -h | awk -f /usr/bin/dfb'

配置了alias之后，dfk,dfg可以正常使用

但是退出session或者重启系统后

alias定义的会失效

在.bashrc中加入上述内容后，永久生效

[root@oracle6 ~]# more .bashrc

# .bashrc

# User specific aliases and functions

alias rm='rm -i'

alias cp='cp -i'

alias mv='mv -i'

alias dfk='df | awk -f /usr/bin/dfb'

alias dfg='df -h | awk -f /usr/bin/dfb'

# Source global definitions

if [ -f /etc/bashrc ]; then

. /etc/bashrc

fi

[root@oracle6 ~]# alias

alias cp='cp -i'

alias dfg='df -h | awk -f /usr/bin/dfb'

alias dfk='df | awk -f /usr/bin/dfb'

退出session或者重启系统后还可以正常使用alias内容

[root@oracle6 ~]# dfk
