andynic has asked for the wisdom of the Perl Monks concerning the following question:
Section 1: the code
Section 2: what is in the directory using ls -l
Section 3: what the code outputs.
Section 1: =========================================================
use strict; use gfrmGlobals; my @files = (); my $flNm = ""; opendir (DIR, $GCdfltDBexpPrmPthNm) || die "can't open directory\n"; @files = readdir(DIR); closedir (DIR); foreach $flNm (@files) { if ( -f $flNm) { print "is a file: $flNm\n"; } elsif ( -d $flNm) { print "is a dir: $flNm\n"; } else { print "neither file nor dir: $flNm\n"; } }
Section 2: From a terminal window =========================================================
gfrmDev$ cd DBexportFiles gfrmDev$ ls -l total 1536 -rw-r--r-- 1 andynic staff 66192 17 Feb 17:43 export_of_gfrm_20110217_ +174314.zip -rw-r--r-- 1 andynic staff 66192 17 Feb 17:51 export_of_gfrm_20110217_ +175005.zip -rw-r--r-- 1 andynic staff 66193 17 Feb 18:30 export_of_gfrm_20110217_ +183048.zip -rw-r--r-- 1 andynic staff 66193 17 Feb 22:08 export_of_gfrm_20110217_ +220832.zip -rw-r--r-- 1 andynic staff 505830 17 Feb 20:27 importLogOf_export_of_g +frm_20110217_183048.log drwxr-xr-x 7 andynic staff 238 18 Feb 12:52 xxxx
Section 3: The code output; ========================================================= (I would have expected 5 files (*.zip, and *.log) and 3 directories (., .., xxxx), but instead:
gfrmDev$ perl -w x.pl is a dir: . is a dir: .. is a file: .DS_Store neither file nor dir: export_of_gfrm_20110217_174314.zip neither file nor dir: export_of_gfrm_20110217_175005.zip neither file nor dir: export_of_gfrm_20110217_183048.zip neither file nor dir: export_of_gfrm_20110217_220832.zip neither file nor dir: importLogOf_export_of_gfrm_20110217_183048.log neither file nor dir: xxxx
Am I doing something weird that I don't see?
perl version 5.10
Mac OS X 10.6
Thanks,
Andynic
