Hi guys,

I've been trying to investigate why these two scriptlets give different results:

1.

obcy:~ kor$ for file in "an example"; do echo $file; done
an example

2.

obcy:~ kor$ for file in `echo \"an example\"`; do echo "["$file"]"; done
["an]
[example"]

i'd be gratefull for any hints

Greetings,
Radek.

It seems that adds a \n character in the middle for some odd reason. I'm not sure why it's doing it. But since you print $file with [] on both sides, and those [] appear around both words in the second example. It makes me thing tha t there is a newline character added somewhere.

Hi and thanks for your answer,

in fact it doesn't need to be a new line since list separators are, as far as I know, any blank characters which are not escaped. The question really is why the quotes are passed to the output without being interpreted by the outer shell (which explains line-break)

Greeting,

well \" is the escape for " as is \\ the escape for \ etc etc etc so you are telling the compiler to ignroe the queotes as normal programming and include them as the string.
