Tambahan pada ~/.bash_aliases

# my personal Aliases list #
# to create the file  nano ~/.bash_aliases

# **** DIRECTORY LISTING in human-readable units ****
alias ll="ls -lhAF"
alias ..="cd .."
alias ...="cd ../../../"
alias back="cd $OLDPWD"

alias lsmount="mount |column -t"

# * Disk Space Usage in human-readable units,  including filesystem type *
alias dfh="df -Tha --total"

alias df="df -h --exclude=squashfs"

# * ALL files in a directory listed,  according their size *
alias du="du -ach | sort -h"

# * listing process table in detail *
alias psa="ps auxf"

alias dmesg="dmesg --human"

# * How to really CLEAR the terminal *
alias clr='printf "\033c"'

alias h="history"

# reload bash config
alias reload="source ~/.bashrc"

Sekarang bisa dieksekusi reloadnya dengan command: . ~/.bashrc pada terminal

Ada spasinya yak, antara titik . dan ~/.bashrc
