Echoing a variable or other expression without quoting it will remove any leading and trailing whitespace.

Code:
echo `wc -l <profile.ksh`

Usually echo `backticks` is mainly seen in really horrible newbie code, but the whitespace normalization is a useful and in this case desired side effect which makes this a legitimate use IMHO.

Note the use of redirection to avoid the Useless Use of Cat.

Are you sure about the AIX spacing issue, though? The situation where you usually see this is when you use wc -l file instead of wc -l <file (but then of course you get the file name also).
