是否有“perl”本身的手册页？

概述我想找出perl -T的含义. 男子佩尔说： PERL(1) Perl Programmers Reference Guide PERL(1)NAME perl - The Perl 5 language interpreterSYNOPSIS 我想找出perl -T的含义.

男子佩尔说：

PERL(1)                               Perl Programmers Reference GuIDe                               PERL(1)name       perl - The Perl 5 language interpreterSYnopSIS       perl [ -sTtuUWX ]      [ -hv ] [ -V[:configvar] ]            [ -cw ] [ -d[t][:deBUGger] ] [ -D[number/List] ]            [ -pna ] [ -Fpattern ] [ -l[octal] ] [ -0[octal/hexadecimal] ]            [ -IDir ] [ -m[-]module ] [ -M[-]'module...' ] [ -f ]      [ -C [number/List] ]      [ -S ]            [ -x[dir] ]      [ -i[extension] ]            [ [-e|-E] 'command' ] [ -- ] [ programfile ] [ argument ]...

然后解释这些命令行参数.

在哪里可以找到这些命令行参数的manpage / perldoc？

解决方法 看看perldoc perlrun(“如何执行Perl解释器”)：

-T

forces “taint” checks to be turned on so you can test them.
Ordinarily these checks are done only when running setuID or
setgID. It’s a good IDea to turn them on explicitly for programs
that run on behalf of someone else whom you might not necessarily
trust,such as CGI programs or any internet servers you might
write in Perl. See perlsec for details. For security reasons,
this option must be seen by Perl quite early; usually this means
it must appear early on the command line or in the #! line for systems which support that construct.
