问题 I'm taking this course from cs50.tv, which is Harvard extension school and in the course they are using a library they made called cs50 , on this link its available for download https://manual.cs50.net/CS50_Library#Mac_OS I downloaded the zip file and unzipped it, and then I open the terminal and cd my way to the library directory, but every time I follow the steps in the manual.

问题 I can't use my zsh shortcuts to move the caret by word in PhpStorm's integrated terminal window using i.e. ⌥ → like I use in Terminal App on my Mac. I have tried to use zsh as shell path in PhpStorm but my default zsh color scheme is not showing well inside of PhpStorm. Seems that also Mac Terminal->Settings shortcuts are not being enabled inside PhpStorm terminal. 回答1: I have found out that it work only if I bind the shortcuts directly in my ~/.bash_profile , by adding this at the bottom:

问题 I am trying to use sed in a script but it keeps failing. The commands on their own seem to work so I am not sure what I am doing wrong: This is in Terminal in OS X (bash) NOTE: file1.txt contains multiple lines of text N=1 sed -n $Np < file1.txt > file2.txt CONTENT=$(cat file2.txt) echo $CONTENT If I change $N to 1, it works perfectly sed -n 1p <file1.txt >file2.txt CONTENT=$(cat file2.txt) echo $CONTENT gives me content of file2.txt So basically, I am trying to copy the text from line 1 of a

问题 To replace all occurrences of a word with another in all files with a particular extension in the current directory I use this command: find . -type f -name '*.zz' -exec sed -i '' "s/replace_this/with_this/" {} + The problem is that it adds \n to the end of files that do not end in \n . Now don't get me wrong, I love \n terminated files as much as the next person. But I don't want all those changes in my git diff. What's a command to run that does the same thing but without touching file

问题 I'm writing a terminal game build on ncurses . I should ensure the window in suitable size. How to adjust terminal window display 20 lines when running the process?

I then use C-h k C-S-DEL to check what happened when I press this hotkey. It says that, only DEL key is recognised other than Ctrl + Shift + DEL . I install this emacs (version 24.5.1) via Homebrew and run it in iTerm2. It does't have a GUI version (I prefer to use in terminal), and is launched simply via emacs command. How
