incorrect syntax when using mkpath

steph_bow has asked for the wisdom of the Perl Monks concerning the following question:

Dea Monks,

I have an incorrect syntax when using mkpath but I cannot correct my error. I want to create the directories but it does not seem to work. Could you help me ? Thanks

Here is my code :

#! usr/bin/perl -w
use strict;


use File::Copy;
use File::Path;

my $date = $ARGV[0];

my $comptage = $ARGV[1];
my $C = $comptage;

# index : input ou output
my $index = $ARGV[2];
my $I = $index;

my $week = $ARGV[3];
my $W = $week;

print STDOUT "the week is ${W}\n";


my $cmda=qq{mkpath('M1_fa_${W}/M1_${W}_comptage_${C}_${I}_first_action
+')};
my $cmdb=qq{mkpath('M2_fa_${W}/M2_${W}_comptage_${C}_${I}_first_action
+')};
my $cmdc=qq{mkpath('M3_fa_${W}/M3_${W}_comptage_${C}_${I}_first_action
+')};
system($cmda);
system($cmdb);
system($cmdc);

I get the error message

sh -c: line 0: syntax error near unexpected token ' 'M3_fa_W42/M3_W42_
+comptage_60_output_first_action' '

`mkpath` is not a command on your system, but a perl function: `use File::Path qw(mkpath); ... mkpath("M1_fa_$W/M1_${W}__comptage_${C}_${I}_first_action"); ...` [download] If you want to use system for some other reason (usually not recommended), the unix equivalent is `mkdir -p`. (BTW you might want to use sprintf to create the file names, that could be much easier than your interpolation).	[reply] [d/l] [select]

The syntax is OK: X:\>perl -c tmp.pl tmp.pl syntax OK X:\>type tmp.pl #! usr/bin/perl -w use strict; use File::Copy; use File::Path; my $date = $ARGV[0]; my $comptage = $ARGV[1]; my $C = $comptage; # index : input ou output my $index = $ARGV[2]; my $I = $index; my $week = $ARGV[3]; my $W = $week; print STDOUT "the week is ${W}\n"; my $cmda=qq{mkpath('M1_fa_${W}/M1_${W}_comptage_${C}_${I}_first_action +')}; my $cmdb=qq{mkpath('M2_fa_${W}/M2_${W}_comptage_${C}_${I}_first_action +')}; my $cmdc=qq{mkpath('M3_fa_${W}/M3_${W}_comptage_${C}_${I}_first_action +')}; [download] Maybe you want to be more explicit about where your problem is, that is, what your program should do, what it does, and how that differs from what you expect. Maybe it is already enough for you to read the quotes section in perlop, Quote and Quote-like Operators.	[reply] [d/l]

... and to add to Moritz comment, to form the path in a way that is more portable see the File::Spec module in CPAN, specifically the catfile method... Finally, you probably have this module already, depending on what version of Perl you are running. Pancho	[reply]
