Homework and Emergencies Emergency UNIX and Linux Support Waiting for wildcard filename to exists in while loop Post 302917000 by RudiC on Saturday 13th of September 2014 04:17:01 AM

The while doesn't - it couldn't care less. The test -f does - and has to. It needs exactly one single file, or it will issue an error msg. Don't use the double quotes as they prevent the shell from evaluating the wild card.

ksh(!93) for loop with wildcard and empty directory

I'm sure this is by design, but using something like for f in dir/* do echo $f done produces unexpected (to me) results if run against an empty directory. I'd have expected it to not execute the loop, but it actually calls it with f set to 'dir/*'. Now I know that I'm trying to protect... (2 Replies)

Perl::Critic::Policy::ValuesAndExpressions::ProhibitQuotPerl::Critic::Policy::ValuesAndExpressions::ProhibitQuotesAsQuotelikeOperatorDelimiters(3)

NAME
Perl::Critic::Policy::ValuesAndExpressions::ProhibitQuotesAsQuotelikeOperatorDelimiters - Don't use quotes ("'", """, "`") as delimiters for the quote-like operators. AFFILIATION
This Policy is part of the core Perl::Critic distribution. DESCRIPTION
With the obvious exception of using single-quotes to prevent interpolation, using quotes with the quote-like operators kind of defeats the purpose of them and produces obfuscated code, causing problems for future maintainers and their editors/IDEs. $x = q"q"; #not ok $x = q'q'; #not ok $x = q`q`; #not ok $x = qq"q"; #not ok $x = qr"r"; #not ok $x = qw"w"; #not ok $x = qx`date`; #not ok $x =~ m"m"; #not ok $x =~ s"s"x"; #not ok $x =~ tr"t"r"; #not ok $x =~ y"x"y"; #not ok $x =~ m'$x'; #ok $x =~ s'$x'y'; #ok $x = qr'$x'm; #ok $x = qx'finger foo@bar'; #ok CONFIGURATION
This policy has three options: "single_quote_allowed_operators", "double_quote_allowed_operators", and "back_quote_allowed_operators", which control which operators are allowed to use each of "'", """, "`" as delimiters, respectively. The values allowed for these options are a whitespace delimited selection of the "m", "q", "qq", "qr", "qw", "qx", "s", "tr", and "y" operators. By default, double quotes and back quotes (backticks) are not allowed as delimiters for any operators and single quotes are allowed as delimiters for the "m", "qr", "qx", and "s" operators. These defaults are equivalent to having the following in your .perlcriticrc: [ValuesAndExpressions::ProhibitQuotesAsQuotelikeOperatorDelimiters] single_quote_allowed_operators = m s qr qx double_quote_allowed_operators = back_quote_allowed_operators = SUGGESTED BY
