Re: [bug-gawk] Gawk feature request - file list

[Manuel Collado]

Can you use wildcards? Most windows ports of gawk do not expand 
wildcards in the shell, but inside the gawk executable. Quick test 
(warning, long line wrapped):

H:\WINDOWS\system32>gawk "{print ARGIND, FILENAME; 
len+=length(FILENAME)+1; nextfile} END{print len}" * * *
1 $winnt$.inf
...
7269 zipfldr.dll
84951

So the equivalent command line length, with wilcards expanded, would be 
84951 characters.

HTH.
