I'm executing the following command and the output is not going to the
move.log file. Am I missing something in the command? 



find /db_backups/30_plus_days -type f -mtime +90 -exec mv /db_backups/90_plus_days/ >> /db_backups/move.log 2>&1 ;



linux find mv exec

    mv (without the -v or --verbose option) doesn't usually produce standard output - what are you expecting exactly?

  • The find command, in the way that it is being used here, does nat produce any output.

  • That did it. Thanks. Was trying to just generate a record of what files were getting moved.

Your find command line:



find /db_backups/30_plus_days -type f -mtime +90 -exec mv /db_backups/90_plus_days/ >> /db_backups/move.log 2>&1 ;


is the same as



find /db_backups/30_plus_days -type f -mtime +90 -exec mv /db_backups/90_plus_days/ ; >>/db_backups/move.log 2>&1


The find command, when used in this way, will not produce any output at all and therefore no new data will be written to the move.log file.



If you wanted to store the names of the files that were moved, add -print before the -exec:



find /db_backups/30_plus_days -type f -mtime +90 -print -exec mv /db_backups/90_plus_days/ ; >>/db_backups/move.log 2>&1


or, with nicer line-breaks (only for readability):



find /db_backups/30_plus_days 
 -type f -mtime +90 -print 
 -exec mv /db_backups/90_plus_days/ 2>&1 ; 
 >>/db_backups/move.log

  • Actually, -print -exec mv ... will print the names of the files before the command tries to move them. But doing it the other way around, -exec mv ... ; -print will only print them after the move has successfully completed (and will not print if it fails)

  • @ilkkachu But if it fails I'd assume that mv would say something, which in turn would go into the log.

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
