I have two files:



~/Pulpit/kot$ find . -name "*jpg" -printf "%fn"
1.jpg
`[~!($%^_&*).___"`]`1.jpg


I want to change their name to:



_home_pic_Pulpit_kot_1.jpg

_home_pic_Pulpit_kot_`[~!($%^_&*).___"`]`1.jpg


I use this command:



~/Pulpit/kot$ find $PWD -name "*.jpg" | mawk 'c=$0; gsub("/", "_", c)system("echo mv -v " $0 " " c)'
mv -v /home/pic/Pulpit/kot/1.jpg _home_pic_Pulpit_kot_1.jpg
/bin/sh: Syntax error: word unexpected (expecting ")")


EDIT:



This command works.



find $PWD -name "*.jpg" -exec bash -c 'mv "$0" "$0////_"' ;


How to do the same with mawk?



EDIT- 1:



This solution works:



find $PWD -name "*.jpg" | mawk 'a=$0gsub("/", "_")system("mv -v '"'"'" a "'"'"' '"'"'" $0 "'"'"'")'


find $PWD -name "*.jpg" | mawk 'a=$0gsub("/", "_")system("mv -v '''" a "''' '''" $0 "''' ")'


find $PWD -name "*.jpg" | mawk 'a=$0gsub("/", "_")system("mv -v 47" a "47 47" $0 "47 ")'

    Do you really have a file named ./`[~!($%^_&*).___"`]`1.jpg? I am utterly horrified. I generally stick to the POSIX Portable Filename Character Set. What are you trying to do?

    Are you sure / is in file name? Like in your output seems ./ is just added by find. Try find . -name "*jpg" -printf "%fn" instead to output it without ./ in the begin.

    @nowy I'm a bit confused by what you are doing. / is never a valid character in a file name because it is the path separator. Replacing / in a path means moving the files to a completely directory, not just a simple file name transformation. Whereas ./file is rather ordinary, ._file is a dotfile / hidden file, whereas dir/file becomes dir_file. Is that really what you intend?

You probably just need to put single quotes around the filename arguments to mv. It's ugly but...



change



system("echo mv -v " $0 " " c)


to 



system("echo mv -v '"'"'" $0 "'"'"' '"'"'" c "'"'"'")

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
