# Useful shortcut to quickly open .bashrc and source it
alias bashrc="vi ~/.bashrc; source ~/.bashrc"

# Make a patch file between two source trees
alias make_patch="diff -uNr"

# Clear the screen of your clutter
alias c="clear"
alias cl="clear;ls;pwd"

# Make grep use color by default, and make a shortcut to using perl regex
alias grep="grep --color"
alias grepp="grep -P --color"

# Shortcuts for various ls options.  All of these add colors, ignore files
# ending with '~', and add '/' to the end of folders.  Shortcuts ending
# with 'a' show hidden files as well, except the redundant '.' and '..'.
alias ls="ls -pB --color"
alias la="ls -pA --color"
alias ll="ls -phl --color"      # long-form list
alias lla="ls -phlA --color"   
alias lz="ls -pshS --color"     # sort by file size
alias lza="ls -pshSA --color"
alias lt="ls -pghotr --color"   # long-form, sort by modification date
alias lta="ls -pghotrA --color"
alias lx="ls -pghoX --color"    # sort by file extention
alias lxa="ls -pghoXA --color"
alias lr="ls -ARpsh --color"    # recursive list (watch out!  It will fill your screen!)

# Make some of the file manipulation programs verbose
alias mv="mv -v"
alias rm="rm -v"
alias cp="cp -v"

# Prints disk usage in human readable form
alias d="du -sh"

# Removes transparency when displaying an image
alias show="display -flatten"

Thanks for sharing! I'll be putting many of these useful things into my own bashrc. I'm glad I'm not the only one who made myself a "bashrc" alias!
