Linuxlike Ctrl-C (KeyboardInterrupt) for the Windows cmd line?

ぃ、小莉子 提交于 2019-12-18 14:17:32
问题 I've been forced into using a command line in windows and wondered if there were Linux-like keyboard shortcuts? I googled and didn't find what I was looking for. Things like ^C, ^Z and such? Thanks all! 回答1: You can trap ^C on Windows with SIGINT, just like Linux. The Windows shell, such as it is, doesn't support Unix style job control (at least not in a way analogous to Unix shells), and ^Z is actually the ^D analog for Windows. 回答2: Try Ctrl + Break : some programs respond to it instead of

How to manually symbolicate a crash log with atos

一个人想着一个人 提交于 2019-12-18 13:38:44
问题 After searching all over the internet to find a way to symbolicate my crash logs I received from Apple, I finally figured out how to use the atos command in terminal to symbolicate the crash logs. I have the dSYM file, the .app file and the crash logs in the same folder, and using atos -arch armv7 -o APPNAME I have been able to enter memory addresses, and sometimes (but quite rarely) a method name has come up. To be perfectly honest, I don't have much experience with terminal, or crash logs.

问题 I have this code to color my terminal: export PS1="\e[1;30m\][\e[\e[1;30m\]\e[1;33m\] \u@\H \[\e[1;32m\]\w\[\e[0m\] \e[1;30m\]]\n[\[ \e[1;31m\]\T\[\e[0m\]\e[1;30m\] ] > \e[37m\]" But I have one problem, when text should be in the new line it overwrites the first line. Example: 回答1: In order for bash to figure out how much screen space your prompt takes up (and therefore where the actual command line starts), you have to enclose the non-printing parts of the prompt in \[...\] .

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 7 years ago . I know it's been asked but what I've found has not worked out so far. The closet I came is this : rename -n 'y[A-Z]/[a-z]/' * which works for the current directory. I'm not too good at Linux terminal so what should I add to this command to apply it to all of the files in all the sub-directories from which I am
