Could someone explain the following behaviour for me? Because I sure
do not understand it.
Yes this is confusing but not incorrect.
[EMAIL PROTECTED]:/tmp/foo$ touch 1 2 3 4 5
[EMAIL PROTECTED]:/tmp/foo$ foo=`ls`
$foo will contain the string 1\n2\n3\n4\n5\n
[EMAIL PROTECTED]:/tmp/foo$ /bin/echo $foo
1 2 3 4 5
This will first parse the string into seperate
parameters to pass to echo which it outputs with spaces in between
[EMAIL PROTECTED]:/tmp/foo$ /bin/echo "$foo"
1
2
3
4
5
The quotes stop the parsing of the string into seperate params,
so echo will output the unparsed string containing newlines.
