shell - Trying to move a file to another directory with the inode number attached -


so have slight issue code. trying move file users wants in deleted directory. situation file needs have inode attached within deleted directory in form $filename_$inode. instance, in home directory have file named good.txt. want move deleted directory , file should in format of good.txt_12234. should do? tried using brace expressions here reason keep getting errors. i've attached part of code below. once solve issue, rest of code work. everyone!

   echo "safe_rm cannot remove '$1' : directory"  38       exit 1  39       fi  40   }  41 error_checking $1  42  43 ## test 3 error conditions based on file given.  44  45 ##5.  46  47 file_inode(){  48  49 filename="$1"  50 inode=$(ls -i "$1"| cut -d" " -f1)  51 mv $1 $home/deleted  52 }  53  54 file_inode $1

update: able kind of figure out problem. did following: mv $1 $home/deleted/$1_$inode. file able move deleted directory. however, when try .restore.info, keeps showing message ls: cannot find "$1"- no such file or directory? did wrong on part? i'll attach code better analysis. thank again everyone.

 error_checking(){  25  26 filename=$1  27   if [ ! -e "$1" ] ;  28        29       echo "safe_rm :cannot remove '$1' : no such file or directory"  30     exit 1 #will stop script if there no file or directory  31   elif [ $# -eq 0 ] ;  32        33       echo "safe_rm : missing operand"  34       exit 1  35   elif [ -d "$1" ] ;  36      37       echo "safe_rm cannot remove '$1' : directory"  38       exit 1  39       fi  40   }  41 error_checking $1  42  43 ## test 3 error conditions based on file given.  44  45 ##5.  46  47 file_inode(){  48  49 filename="$1" 50 inode=$(ls -i "$1"| cut -d" " -f1)  51 mv "$1" $home/deleted/$1_$inode  52 }  53  54 file_inode $1  55  56 ##this move file recycle bin , format filena    me_inode.  57  58 ##6  59  60 movefile(){  61  62 filename=$1  63 inode=$(ls -i $1| cut -d" " -f1)  64 touch $home/.restore.info  65 readlink=$home/deleted/$1_$inode  66 path=$(readlink -m $1)  67 echo "$1_$inode:$path">> $home/.restore.info

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

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
