powershell - Script to organize folders -


i need organize many folders, folders must have kind of format in names. need rename them , put them this:

parent folder 2nd name + "_" + 2 digits + "_" + folder name

this needs happen every folder .ps1 executed.

here better explanations, here have folders:

 00_00_master folder +- 00_01_activities `- 00_02_schedules    +- 02_00_dir1    `- 02_01_dir2

as can see, subfolders inside 00_02_schedules start 2nd "name".

etc, folders (never files). better explanation, added (it happen lot) 3 more folders inside 00_02_schedules. should (before , after executing .ps1)

before:

 ... `- 00_02 schedules    +- 02_00_dir1    +- 02_01_dir2    +- dir3    +- 12345dir4    `- 01_01_dir5

after:

 ... `- 00_02 schedules    +- 02_00_dir1    +- 02_01_dir2    +- 02_02_dir3    +- 02_03_dir4    `- 02_04_dir5

i try explain little (i put code had, when think useless now)

$var1 = 0 $var2 = 0 # has work in same place, never fixed path # c:\users\etc\etc $arr1 = get-childitem -path .\ -directory  $arr2 = new-object system.collections.arraylist [string]$dir = get-location  $ruta = $dir | split-path -leaf  # did these 2 things because needed folder's name, didn't know how  # better  # think can following code useless now, think tried # array of arrays cleave name   foreach ($name in $arr1) {     [void]$arr2.add($name) }  foreach ($directory in $arr1) {     if ($directory -match '^[0-9].*') {         rename-item \$directory -newname { [string]($_.name).substring(5) }           # part i've being having problems with. may         # code works...as long folder's name doesn't start number,         # because enters inside loop , many error logs pops out.         # renames folders renamed 00_01_00_01, when it's         # supposed delete before rename them.          # also, think won't work if numeric extension isn't equal 5.     } }  $arr3 = $ruta -split '_' $foldername = $arr3[1] # works, splits , give me second "piece" between 2 "_"  foreach ($directory in $arr1) {     rename-item "$directory" -newname $("$foldername" + "_" + "$var1" + "$var2" + "_" + $directory.name)      # think should have been: (i put way before)      # $("$foldername" + "_" + "$var2" + "$var1" + "_" + $directory.name)     # if did way, renamed them 10,20,30 instead of 01,02,03 etc.      $var++      if ($var1 = 9) {         $var1 = 0         $var2++         # suppose not fancy, in result output can see 2 numbers, not 1     } }

one more thing, possible transform (fixed) code work in folders in recursive way? (would save lot of work , executions).

with initial situation:

> tree └───00_00_master folder     ├──00_01_activities     └──00_02_schedules        ├──01_01_dir5        ├──02_00_dir1        ├──02_01_dir2        ├──12345dir4        └──dir3

this script (adapt set-location fit environment):

## q:\test\2017\08\18\so_45750567.ps1 function test-dirschema ($dirname) {     # assume parent processed , complies schema     $thisdir = gi $dirname     # parent's second number our first     $first = $thisdir.parent.name.split('_')[1]     if ($thisdir.name -match "^$($first)_\d{2}_.*") {         "{0} : {1} complies schema" -f $first,$thisdir.name     } else {         $highest = (gci "$($thisdir.parent)\$($first)_??_*"|sort|select -last 1).name         $second = [int]($highest -replace('^\d{2}_(\d{2})_.*','$1'))         $second = ($second + 1).tostring('00')         "{0} : {1} not comply schema" -f $first,$thisdir.name         $newname = "{0}_{1}_{2}" -f $first, $second,$thisdir.name.trimstart('0123456789_')         "new: {0}" -f $newname         $thisdir | rename-item -newname $newname     }     "----" } set-location "a:\00_00_master folder"  get-childitem "[0-9][0-9]_*" -rec |     where-object {$_.psiscontainer} |         foreach-object {test-dirschema $_.fullname}

with output:

>  q:\test\2017\08\18\so_45750567.ps1 02 : 01_01_dir5 not comply schema new: 02_02_dir5 ---- 02 : 02_00_dir1 complies schema ---- 02 : 02_01_dir2 complies schema ---- 02 : 12345dir4 not comply schema new: 02_03_dir4 ---- 02 : dir3 not comply schema new: 02_04_dir3 ----

will have end situation:

> tree └───00_00_master folder     ├──00_01_activities     └──00_02_schedules        ├──02_00_dir1        ├──02_01_dir2        ├──02_02_dir5        ├──02_03_dir4        └──02_04_dir3

the order is, due different sorting, not yours. if there no previous number start 01.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
