The line set lang to do shell script "defaults read NSGlobalDomain AppleLanguages" returns an string, which looks like ( en, de, ja, fr, es, it, pt, "pt-PT", nl, sv, nb, da, fi, ru, pl, "zh-Hans", "zh-Hant", ko, ar, cs, hu, tr ) returns the users languages, but how can I get the first one of this 'array'?

问题 I have a special application (8051 simulator from ucsim) on a local server that transmits and expects non-printable characters on only one port. Essentially, I'm defining my own data format. Telnet would have been the perfect program if I can see the hex codes of each character returned back in 30 columns as well as being able to type hex codes of characters going out.

问题 Duplicate Unable to remove everything else in a folder except FileA I guess that it is slightly similar to this: delete [^Music] However, it does not work. 回答1: Put the following command to your ~/.bashrc shopt -s extglob You can now delete everything else in the folder except the Music folder by rm -r !(Music) Please, be careful with the command. It is powerful, but dangerous too. I recommend to test it always with the command echo rm -r !(Music) 回答2: The command rm (ls | grep -v '^Music$')

问题 I'm trying to run source /Users/alastair/.rvm/scripts/rvm , but keep getting: Bad : modifier in $ ("). Where would the problem be? Happy to paste other files in if these would help. 回答1: Are you in any case running a shell that is not Bash or ZSH ? Bash >= 3.2.25 or ZSH >= 4.3.10 is required. Your problem looks like you were using minimalistic shell sh which is not supported by RVM . You can check user shell in /etc/passwd and change it with chsh -s /path/to/new/shell - list of allowed shells

问题 I am trying to create a file in OS X that is essentially a package that has files in it, similar to how a Logic project is a single file but contains all of the audio files within it (when you right-click the file it has the "Show Package Contents" option). Doing this in Swift would be great, but also curious just in general how this is done? I haven't had much luck. 回答1: You need to define a "Document Package" type. Basically these "packages" are just a directory with a file extension

问题 I am trying to run a very simple tmux shell script called "split.sh" which splits the terminal windows. split.sh: #!/bin/bash ~/build/tmux-1.5/tmux split-window -h ~/build/tmux-1.5/tmux split-window -v ~/build/tmux-1.5/tmux split-window -h When I type the command "sh ~/build/tmux-1.5/split.sh", this shell script runs fine, splitting the terminal windows.

问题 I want to use setfillstyle() and textcolor() in UBUNTU(terminal) . But I found on internet that it is store in conio.h library which cannot be used in UBUNTU . So what should I do ? 回答1: The de facto way to do these things on unixy terminals today is to use some Curses libray, which on Ubuntu is Ncurses library developed by GNU Project. Google for "ncurses tutorial" to get started. It is different from conio.h , so just learn it from scratch. 回答2: That's true. setfillstyle and textcolor are
