It requires no installation, Homebrew, or dependencies, and supports files, clipboard output, windows, regions, timers, displays, silent captures, and automation. ## Why use the terminal for screenshots? Keyboard shortcuts suit one-off captures, but the command line supports repeated captures, naming conventions, precise coordinates, and CI integration. ## Basic usage ```bash screencapture screenshot.png ``` This saves `screenshot.png` in the current working directory. Use any path: ```bash screencapture ~/Desktop/capture.png ``` The extension determines the format: ```bash screencapture capture.jpg screencapture capture.pdf screencapture capture.tiff ``` PNG is described as lossless, JPG as smaller, and PDF as vector-friendly. ## Interactive selection mode ```bash screencapture -i selection.png ``` `-i` works like **Cmd+Shift+4**. Press **Space** during selection to switch to window capture. Add `-o` to remove the window shadow: ```bash screencapture -i -o clean-window.png ``` ## Window capture ```bash screencapture -w window.png screencapture -w -o window-no-shadow.png ``` `-w` prompts you to click a window; `-o` removes its drop shadow. ## Capture a specific region by coordinates ```bash screencapture -R 100,200,800,600 region.png ``` `-R` takes an **800×600-pixel** rectangle beginning at **(100, 200)** from the screen's top-left corner, without manual selection. ## Clipboard output ```bash screencapture -c ``` Combine `-c` with other modes: ```bash screencapture -c -i # Interactive selection to clipboard screencapture -c -w # Window capture to clipboard screencapture -c -R 0,0,500,400 # Region to clipboard ``` Paste with **Cmd+V** into Slack, GitHub, or an AI coding assistant. ## Timed captures ```bash screencapture -T 5 delayed.png ``` `-T` waits five seconds before capturing, allowing time to trigger dropdowns, tooltips, or hover states in another app. ## Capture specific displays ```bash screencapture -D 1 main-display.png # Main display screencapture -D 2 second-display.png # Second display ``` Without `-D`, `screencapture` captures all screens in one image or creates separate files when given multiple filenames: ```bash screencapture screen1.png screen2.png ``` ## Useful flag combinations | Command | What it does | | --- | --- | | `screencapture -i -o file.png` | Interactive selection, no window shadow | | `screencapture -c -i` | Interactive selection to clipboard | | `screencapture -T 3 -i file.png` | 3-second delay, then interactive selection | | `screencapture -R 0,0,1920,1080 file.png` | Capture a specific 1080p rectangle | | `screencapture -t jpg -x file.jpg` | JPEG format, no capture sound | | `screencapture -x file.png` | Full-screen capture, silent | `-x` suppresses the shutter sound. `-t` explicitly sets the image format. ## Scripting: automated screenshot capture ### Time-lapse screenshots ```bash #!/bin/bash mkdir -p ~/Screenshots/timelapse while true; do filename="capture-$(date +%Y%m%d-%H%M%S).png" screencapture -x ~/Screenshots/timelapse/"$filename" sleep 30 done ``` This captures every 30 seconds for monitoring, time tracking, or documenting a multi-step procedure. ### Capture with automatic naming Add this to `~/.zshrc`: ```bash # Add to ~/.zshrc ss() { local dir=~/Screenshots mkdir -p "$dir" local file="$dir/$(date +%Y-%m-%d_%H-%M-%S).png" screencapture -i -o "$file" echo "Saved: $file" } ``` Run `ss`, select a region, and save a name such as `2026-04-01_14-30-22.png`. ### Capture and open in Preview ```bash screencapture -i /tmp/quick-capture.png && open /tmp/quick-capture.png ``` ### Capture and copy file path ```bash ss-path() { local file="/tmp/screenshot-$(date +%s).png" screencapture -i "$file" echo "$file" | pbcopy echo "Path copied: $file" } ``` ## Integration with other tools ### Pipe to ImageMagick Requires ImageMagick: ```bash # Capture and resize to 50% screencapture -i /tmp/cap.png && magick /tmp/cap.png -resize 50% output.png # Capture and convert to WebP screencapture -i /tmp/cap.png && magick /tmp/cap.png output.webp ``` ### Capture and upload via curl The example uses a placeholder endpoint from the source: ```bash # Capture and upload to a file hosting API screencapture -i /tmp/upload.png && \ curl -F "file=@/tmp/upload.png" https://your-upload-endpoint.com/api/upload ``` ### Git commit with screenshot evidence ```bash # Capture UI state and commit alongside code changes screencapture -i docs/screenshots/feature-state.png git add docs/screenshots/feature-state.png git commit -m "docs: add screenshot of feature state" ``` ## Troubleshooting - **Permission denied or blank captures:** In **System Settings → Privacy & Security → Screen Recording**, enable Terminal or your terminal app such as iTerm2. Restart the terminal if necessary. - **Low resolution:** Retina displays capture at native resolution by default, for example **3024×1964** on a 14-inch MacBook Pro. To resize to display-resolution pixels such as **1512×982**, use ImageMagick or: ```bash sips --resampleWidth 1512 screenshot.png ``` - **No sound:** `-x` suppresses the sound. Remove it to restore the shutter sound. ## When the terminal isn't enough `screencapture` does not annotate; it cannot add arrows, highlights, text, or blur before saving or sharing. We handle those annotation and sharing steps in one keystroke and auto-paste captures into Claude, Cursor, and ChatGPT. **$29 one-time.** [Try LazyScreenshots — $29 one-time](https://www.lazyscreenshots.com/) ## Related - [Screenshot to Clipboard on Mac: The Fastest Developer Workflow](https://www.lazyscreenshots.com/blog/screenshot-clipboard-workflow-mac/) - [Mac Screenshot Keyboard Shortcuts: The Complete Cheat Sheet](https://www.lazyscreenshots.com/blog/mac-screenshot-keyboard-shortcuts/) --- ## Ask www.lazyscreenshots.com about this page Public sources, cited, no account or API key.
