Re^2: The "<" in the grep block

This statement allows to use glob in cmd (Win32). Without this line the script if run as:

C:\perl\bin>perl script.pl N:/TEMP/*
[download]

throws the following message:

Use of uninitialized value in numeric lt (<) at script.pl
line 8.
        N:/TMP/*
[download]

I have found this line by BrowserUK some time ago (cannot find the original node now) and I am very grateful for it.

Update: Did not see the post from BrowserUK before I sent my message.

I agree that `@ARGV = map{glob} @ARGV; ....` [download] does work, however, I think since "glob" can do the expansion, why not use `my @smaller_than_1000 = grep { -s $_ < 1000 } glob("@ARGV"); ....` [download] see glob for detail.

That works for this application, but wouldn't for the more common uses: `BEGIN{ @ARGV = map glob, @ARGV } while( <> ) { ... }` [download] And `perl -eBEGIN{@ARGV=map{glob}@ARGV} -nle"1" a.pl b.pl` [download] With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
