I'm trying to customize the prompt in tcsh shell.
for instance say if I were at a directory which is 7 levels deep from the home/user, the prompt displays as below
home/user/L1/L2/L3/L4/L5/L6/L7 >



but I want the prompt to be like this (home/user and the last two directories only )
home/user/.../L6/L7 >




linux prompt tcsh csh

  • FYI csh/tcsh is a terrible shell for interactive use, and even worse for programming. See CSH PROGRAMMING CONSIDERED HARMFUL (note: tcsh fixes some but not all of the bugs of csh, but still has the same design flaws). It is highly recommended to use bash, ksh, or zsh instead...and limit your scripts to using only POSIX sh features if you want to write portable scripts.

  • You can limit the expansion of the CWD to n trailing directories by replacing ~ by c0n or C0n in your prompt - but I don't know a way to trim intermediate directories in the way you are asking. See for example Customizing your shell prompt

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...
