-e：告诉perl在其后的命令行里查找运行代码。当然只能用于输入一行代码执行，如果要运行的代码不止一行，参数就变了。

xk@linux:~/work> perl -e 'print "hello!"n";'

hello!

xk@linux:~/work>

-：告诉perl在其后的命令行里查找运行代码，直到遇到__END__为止。

xk@linux:~/work> perl -

print "hello"n";

print "world!";

__END__

hello

world!xk@linux:~/work>

-c：用来检查脚本的语法而不执行它。

xk@linux:~/work> cat t

#!/usr/bin/perl

print "hello";

xk@linux:~/work> perl -c t

t syntax OK

-h：帮助选项，用来打印perl的全部选项信息。

xk@linux:~/work> perl -h

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)

 -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

 -P              run program through C preprocessor before compilation

 -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, subversion (includes VERY IMPORTANT perl info)

 -V[:variable]   print configuration summary (or a single Config.pm variable)

 -w              enable many useful warnings (RECOMMENDED)

 -W              enable all warnings

 -x[directory]   strip off text before #!perl line and perhaps cd to directory

 -X              disable all warnings

-S：让perl使用PATH环境变量来搜索脚本。

xk@linux:~/work> echo $PATH

/home/xk/bin:/usr/local/bin:/usr/bin:/usr/X11R6/bin:/bin:/usr/games:/opt/gnome/bin:/opt/kde3/bin

xk@linux:~/work> cd ../bin/

xk@linux:~/bin> ls

xk@linux:~/bin> cat >test.pl<<eof

> #!/usr/bin/perl

> print "hello"n";

> eof

xk@linux:~/bin> chmod a+x test.pl

xk@linux:~/bin> cd ../work

xk@linux:~/work> perl -S test.pl

hello

xk@linux:~/work>

-T：强制打开错误检查（数据安全性检查），经常用在CGI中。

-v：打印出perl的版本以及包的级别。

xk@linux:~/work> perl -v
