Re: Re: Test for file(s): glob or -e?

*boggles*

Why grep -e? Does glob make up stuff that doesn't exist in the directory now?

By design, glob only checks for actual existence of files if you include * or ? in that part of the path: `$ echo hi there>foo $ ls foo $ perl -wle'print for glob "{a,b,c,}fo{,}"' afo bfo cfo foo fo` [download] This pattern expands to {afo,bfo,cfo,fo,afo,bfo,cfo,fo}. Only the subpatterns containing a ? or will be restricted to what exists. In the simple case, glob "joe.txt" will always return joe.txt.	[reply] [d/l]
