environment-variables

问题 In Bash (or other shells) how can I print an environment variable which has a multi-line value? text='line1 line2' I know a simple usual echo $text won't work out of the box. Would some $IFS tweak help? My current workaround is something like ruby -e 'print ENV["text"]' . Can this be done in pure shell? I was wondering if env command would take an unresolved var name but it does not seem to. 回答1: Same solution as always. echo "$text" 回答2: export TEST="A\nB\nC" echo $TEST gives output: A\nB\nC

问题 Problem: I have recently upgraded from macOS Mojave 10.14.6 to macOS Catalina 10.5.5. Now that zsh is the default shell, I migrated my .bashrc to .zshrc : Aliases work fine. But for some unexplainable reason, my custom user scripts in ~/bin/my/ and ~/bin/dev/ are not completed by autocompletion cannot be evoked when typed entirely, I then get zsh: command not found: myScript.sh Investigation & Troubleshooting: When changing the shell back to bash, everything still works, so data-loss

问题 I would like to test whether GNUPlot is installed on the system on which my program is running. For that, I figured I'll test for the existence of the gnuplot executable in the user's install locations through stat() call. However, I don't know how to read the $PATH environment variable in C so I can test for the existence of the file in those locations. 回答1: To read the PATH environment variable, use getenv("PATH") . However, if you just want to run gnuplot if it's available, and perform

问题 I am trying to use slack to notify when a build is complete or if a build fails on GitlabCI.

问题 I have created a .env file in my project root but I'm new to working with environments / variables and so I'm unsure how to integrate the file so I can override the stock, non-ejected react-app eslint settings. // My .env file has just this EXTEND_ESLINT = "true" The c-r-a docs explain what the variable is, but not now to set it to true. Also, the section on 'Extending the ESLint config' is helpful only for once the var is set to true. // stock create-react-app package.json "scripts": {
