I was hoping this would work:



$ find . -type f -exec basename ; | while EFS= read -r f; do echo "$f##[0-9]"; done


But, for example, for files named as:




1foo

11bar




it returns:




foo

1bar




when




foo

bar




is expected.



PS: ultimately, I want to mv "$f" to the modified name (and also do other modifications)

    Your code is telling it , in effect, to remove 0-9 from the beginning of the filename. If there is more than one digit (two, for example) then you need to change [0-9] to [0-99]. For three, you need [0-999] and so on and so forth.

  • The title says "beginning of file" but your code is gathering filenames and then renaming them. Also, unsetting "EFS" appears to be a typo for unsetting "IFS"

  • Your solution necessitates to know in advance the number of digits. Is there not a more general way? Why doesn't ## take care of it in the parameter expansion?

Displaying single band from multi-band raster using QGIS

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...
