Re: quotes around a variable

[Alex fxmbsw7 Ratchev]

i have figured as such.. quotes are when defining vars ( var=foo ) not
needed, where quotes overall, usually, are needed are when using vars as
arguments, eg ./app "$var" and also arr=( "$1" "$var" )

then when u need to preserve data, such as not interpreting $var in args (
./app '$foo is a var' )

then doublequotes u need where $var must get expanded

simply shortly so.. theres more to say anyway

greets
