It is troublesome to mark the long parameter option of "--color=auto" when grep grabs data, so you can modify the bashrc file in the home directory and add an alias to grep so that it automatically marks the color just like ls. Modify it as follows:

# of course, if you want the global settings of the system, you can put it in the if judgment in the bashrc file Of course, you can also put it directly under the if judgment # by the way, add [root@localhost] # echo-e "alias grep='grep-- color=auto'\ nalias egrep='egrep-- color=auto'" > > ~ / .bashrc [root@localhost] # vim ~ / .bashrc # User specific aliases and functionsalias rm='rm-i'alias cp='cp-i'alias mv='mv-iTunes # Source global definitionsif [- f / etc/bashrc] Then. / etc/bashrc alias grep='grep-color=auto' alias egrep='egrep-color=auto'fi
