Zsh Docker Plugin not Working

阅读更多关于 Zsh Docker Plugin not Working

问题 I have been using oh-my-zsh for a while now and the docker plugin as recently stopped working for me for some reason. I checked my ~/.zshrc file and the plugin is included plugins=(git colored-man colorize github jira vagrant virtualenv pip python brew osx zsh-syntax-highlighting docker) I checked the ~/.oh-my-zsh/plugins/docker directory and there is a _docker file in there. Yet when I type docker and press Tab, I get none of the autocomplete shortcuts that I used to get. I can confirm that

amended line ending with Vagrant & ZSH

阅读更多关于 amended line ending with Vagrant & ZSH

问题 I have a vagrant box where I change the default Ubuntu shell to oh-my-zsh . I have a shared folder containing a .zshrc that I copy to the vagrant home folder during provisioning. At some point the line ending for one line in the .zshrc has ^M appended to it so I get the following error when I vagrant ssh : /home/vagrant/.zshrc:source:4: no such file or directory: /home/vagrant/.oh-my-zsh/oh-my-zsh.sh^M The ^M is not visible in the .zshrc file. If I use vim in the vagrant box and re-write the

How to treat 2 Directories as one in the command line

阅读更多关于 How to treat 2 Directories as one in the command line

问题 I have a script, which takes a list of directories and compares their number of files. What I would like is to sometimes group two or more directories to be treated as one by the script. Of course I could modify the script but I would prefer to do this grouping in the command line. $ ./myscript.sh {dir1 dir2} dir3 dir4 ... should be treated as if {dir1 dir2} was the (mathematical) union of the elements of both directories. How to achieve this? 回答1: You can use an array of directories for this

draw grid with cells of specific size over an image

阅读更多关于 draw grid with cells of specific size over an image

问题 How can I draw a grid, 1px black borders no fill, over an image? Each section of the grid should be 480x360px. E.g., given this 1440x1080px solid white input: It should have a 3x3 grid drawn onto it (because 9 480x360px rectangles fit into it) to make an output kind of like this: That's not as accurate as I'd like the command to be (I was just drawing rectangles by eye), but I hope it illustrates what I'm after. 回答1: Here is a command that will read an input image, create a 480x360

Portable array indexing in both bash and zsh

阅读更多关于 Portable array indexing in both bash and zsh

问题 Array indexing is 0 -based in bash , and 1 -based in zsh (unless option KSH_ARRAYS is set). As an example: To access the first element of an array, is there something nicer than: if [ -n $BASH_VERSION ]; then echo ${array[0]} else echo ${array[1]} fi 回答1: TL;DR: To always get consistent behaviour, use: ${array[@]:offset:length} Explanation For code which works in both bash and zsh , you need to use the offset:length syntax rather than the [subscript] syntax. Even for zsh -only code, you'll

“Pipe stderr, and not stdout” not working in Zsh

阅读更多关于 “Pipe stderr, and not stdout” not working in Zsh

问题 How to pipe stderr, and not stdout? perfecly captures my problem, and the first answer is exactly how I initially tried to solve it: (echo stdout; echo 1>&2 stderr) 2>&1 >/dev/null | less (The subshell command with echos is a minimal placeholder thanks to user1934428 to demonstrate the issue; my actual problem has a more useful command, but one that everyone else can't run.) However, it doesn't work: It's showing both stdout and stderr together. If I remove the pipe, it works as expected,
