copy path

copy STDOUT into clipboard

[!NOTE]

• pbcopy for macOS
• xclip for Linux

$ <cmd> | pbcopy

• example

  $ cat file | pbcopy
  $ pwd | pbcopy
  

Copy path from finder

• right-click(control + left-click) -> option

• Automator -> Quick Action

• Automator -> Apple Script

  on run {input, parameters}
  
    try
      tell application "Finder" to set the clipboard to POSIX path of (target of window 1 as alias)
    on error
      beep
    end try

groovyConsole

[!NOTE|label:expection] case: run groovyConsole from Spolite or Alfred

• reference:
  • Install groovy console on Mac and make it runnable from dock

via Automator.app

[!NOTE|label:tips] Automator.app will create whole bunch of necessary files for app. only need to replace the CFBundleExecutable filename

• Open Automator.app » New » Application

• Select Run Shell Script » save to .app with empty shell script

  

via script

[!NOTE|label:tips:]

• get standalone commands for the script
