### Discovering Helpful Terminal Commands for Mac Users
The Terminal is a robust utility for Mac users, providing a variety of commands that can boost efficiency and facilitate tasks. Below are some lesser-known commands that can enrich your macOS experience.
#### Set an Alarm in Terminal
If you struggle to take breaks while working in Terminal, you can directly set alarms from the command line. Use the command:
“`bash
leave [time]
“`
For instance, to set an alarm for 6:46 PM, type:
“`bash
leave 1846
“`
This command can also accommodate local time formats.
#### Comprehensive Battery Details
To ensure optimal battery health of your Apple devices, you can access detailed battery information using the following command:
“`bash
system_profiler SPPowerDataType
“`
This command reveals details about battery condition, cycle count, and additional information.
#### Retrieve Saved Passwords
You can easily find saved Wi-Fi passwords via Terminal. Input the following command:
“`bash
Security find-generic-password -wa [Wi-Fi Network]
“`
Substitute `[Wi-Fi Network]` with the actual name of the network to obtain the password.
#### Clear Hidden Downloads
To remove your download history, utilize these commands:
1. Display hidden downloads:
“`bash
sqlite3 ~/Library/Preferences/com.apple.LaunchServices.QuarantineEventsV* ‘select LSQuarantineDataURLString from LSQuarantineEvent’
“`
2. Delete the log:
“`bash
sqlite3 ~/Library/Preferences/com.apple.LaunchServices.QuarantineEventsV* ‘delete from LSQuarantineEvent’
“`
#### Alter Default Screenshot File Name
To modify the default file name for screenshots, execute:
“`bash
defaults write com.apple.screencapture name
“`
Replace “ with your chosen title, such as “Security Bite.”
#### Modify Default Screenshot File Format
You can also change the default format for screenshots. For instance, to save screenshots as PDFs, type:
“`bash
defaults write com.apple.screencapture type pdf
“`
Available formats include PNG, JPG, PDF, GIF, and TIFF.
#### Bonus: ASCII Aquarium
For a bit of amusement, you can create an ASCII aquarium in Terminal. First, install Homebrew if you haven’t yet:
“`bash
/bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)”
“`
Then, install Asciiquarium:
“`bash
brew install asciiquarium
“`
Finally, start it with:
“`bash
asciiquarium
“`
