添加一个alias,在shell启动时就生效。可以添加到~/.bashrc。
也可以添加到~/.bash_aliases,因为.bashrc会source这个文件。
1 2 3 4 5 6 7 8 9 10 11 | $ cat ~/.bashrc ... # Alias definitions. # You may want to put all your additions into a separate file like # ~/.bash_aliases, instead of adding them here directly. # See /usr/share/doc/bash-doc/examples in the bash-doc package. if [ -f ~/.bash_aliases ]; then . ~/.bash_aliases fi ... |
添加一个greps别名,grep时排除编译产物和cscope数据库。
1 2 | $ cat ~/.bash_aliases alias greps= 'grep --exclude="*.o" --exclude="*.ko" --color=always --exclude="cscope*"' |
