SPrawdzamy czy mamy interpreter perla. W konsoli wpisujemy :
perl -help
Otrzymujemy :
<pre>
Usage: perl [switches] [--] [programfile] [arguments]
-0[octal] specify record separator (\0, if no argument)
-a autosplit mode with -n or -p (splits $_ into @F)
-C[number/list] enables the listed Unicode features
-c check syntax only (runs BEGIN and CHECK blocks)
-d[:debugger] run program under debugger
-D[number/list] set debugging flags (argument is a bit mask or alphabets)
-e program one line of program (several -e's allowed, omit programfile)
-E program like -e, but enables all optional features
-f don't do $sitelib/sitecustomize.pl at startup
-F/pattern/ split() pattern for -a switch (//'s are optional)
-i[extension] edit <> files in place (makes backup if extension supplied)
-Idirectory specify @INC/#include directory (several -I's allowed)
-l[octal] enable line ending processing, specifies line terminator
-[mM][-]module execute "use/no module..." before executing program
-n assume "while (<>) { ... }" loop around program
-p assume loop like -n but print line also, like sed
-s enable rudimentary parsing for switches after programfile
-S look for programfile using PATH environment variable
-t enable tainting warnings
-T enable tainting checks
-u dump core after parsing program
-U allow unsafe operations
-v print version, patchlevel and license
-V[:variable] print configuration summary (or a single Config.pm variable)
-w enable many useful warnings
