under /home/scrript , we have 187 bash scripts
all the scripts have the following line:



kill -PIPE $PID


we want to add the following words before this line on all the scripts as the following



[[ $KILL_STATUS = YES ]] && kill -PIPE $PID


the reason for that is to avoid editing of each script , and use Linux commands as sed to do in one shoot on all the scripts,






linux text-processing awk sed perl

$ for i in /home/scrript/*; do sed -i 's/kill -PIPE $PID/[[ $KILL_STATUS = YES ]] && kill -PIPE $PID/' "$i"; done


Explanation




  • for i in /home/scrript/*; do FOO; done: repeat for all files in /home/scrript. N.B. depending on your shell configuration this might skip dot files.


  • sed -i 's/kill -PIPE $PID/[[ $KILL_STATUS = YES ]] && kill -PIPE $PID/' "$i": for each file ("$i"), replace "in-place" (sed -i), replacing kill -PIPE $PID with [[ $KILL_STATUS = YES ]] && kill -PIPE $PID. (N.B. you need to escape the & as they have a special meaning otherwise.

            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...
