linux - Cutting the column including size -

-

i want cut column include size of files . use ls -l view info files in current localization . save info file in txt file ls -l > info.txt , , want cut column including size . cat info.txt | cut -d'' -f6 don't work . wrong ?

this include info.txt :

-rwx------ 1 s10891 domain users   2188 may  4 14:51 info.txt -rwx------ 1 s10891 domain users   1640 mar 10 07:43 code.txt -rwx------ 1 s10891 domain users     68 mar  4 11:59 sorted.txt drwx------ 1 s10891 domain users      0 jan 11 09:48 ppj drwx------ 1 s10891 domain users      0 sep  7  2012 public_html drwx------ 1 s10891 domain users      0 apr 15 11:16 rbd drwx------ 1 s10891 domain users      0 jan  7 09:45 rdb drwx------ 1 s10891 domain users      0 apr 15 12:00 sop drwx------ 1 s10891 domain users      0 apr  8 12:53 sop_ex3 -rwx------ 1 s10891 domain users    122 feb 25 11:48 sop_info.txt drwx------ 1 s10891 domain users  0 jan 14 09:41 windowsformsapplicati drwx------ 1 s10891 domain users      0 jan 14 09:41 windowsformsapplicati drwx------ 1 s10891 domain users      0 jan 14 09:41 windowsformsapplicati

and want : 

2188 1640 68 0 0 0 0 0 0 122 0 0 0

most cuts count literal characters, -f 6 work, data has in same columns. not sure if 3rd last line typo or exact reproduction of output, illustrates problem cut perfectly.

for case, people use awk solution:

 ls -l | awk '{print $6}'

will produce output have listed

the beauty of awk field 6 determined value of awk fs variable (field separator), defaults "multiple white space values" (space or tab) (this not exact description, close enough needs).

c++ - Function signature as a function template parameter -

-
i'd use function signature template argument. works great classes, when try same trick function templates, msvc throws error: error c2768: 'func' : illegal use of explicit template arguments here's code: template <typename signature> void func(); template <typename r, typename a1> void func<r(a1)>(); what should make work? you cannot partially specialize function template, not supported language. can create partially specialized class template static member function, , possibly trampoline function instantiate class template , invoke static function. something this: namespace detail { template<typename signature> struct helper; template<typename r, typename a1> struct helper<r(a1)> { static void call() { // stuff r , a1... } }; } template<typename signature> void func() { detail::helper<signature>::call(); }

algorithm - What are some ways to combine a number of (potentially incompatible) sorted sub-sets of a total set into a (partial) ordering of the total set? -

-
i have sorting problem i'm pretty sure doesn't have canonical "answer" - has number of different approaches, each pros/cons. i'm interested in hearing different approaches. suppose bunch of people {p_i | i=1,...,m} ranking favorite ice cream flavors. in total there n different flavors, single person p_i ranks n_i << n flavors or familiar with. i'm interested in combining these sub-rankings plausible overall ranking of n flavors. for concrete situation: m , n both 1000 (by coincidence), , each n_i 20 . can assume there's enough overlap in flavors people rank such no flavor "isolated". again, i'm interested in hearing different ways approach this, if there isn't single clear answer. thanks! one way approach problem construct directed cyclic graph representing of constraints on ordering of elements. nodes in graph represent different elements compared , have edge first node second node if had ranked first e...

-
there's function on page want call after loads. not own page, can't insert html it. can please provide specific examples how chrome extension or greasemonkey?
