Two short details,
ll is an alias commonly used on unix/linux/cygwin
most often standing for "ls -l" in its simplest form.
Mine does a few other things

alias llg='ls -l'         #long listing

alias ll='llg -gG'        # same with user+group turned off

lsacl is a shell script I use to get a more convenient and
compact form of acl's on linux; laster ported it to cygwin to do the same:


Here it is -- feel free to pass it along:
