~/bin scripts

===========

A bunch of ~/bin utilities for Linux (though most will probably work on Mac OS X too). Several of them will need Ruby as well as certain Ruby gems.

This repository is no longer actively maintained for the moment, and certain tools (such as tog) that rely on webscraping, likely no longer work.

age

A CLI Ruby script that returns your (Terran) age in various descriptions, based on your date of birth. To get your own age, configure the script with your date (and possibly even hour!) of birth and call the script without any arguments. You can also pass some date in the past to get the time that has passed since that time, for instance to get someone else's age.

Examples:

$ age
I was born 15786.81 Terran days, or 378883 hours and roughly 32 minutes ago. This makes me about 22733012 minutes (or about 43.22 Terran years) old
$ age 2 November 1981
You were born 11463.82 Terran days, or 275131 hours and roughly 33 minutes ago. This makes you about 16507893 minutes (or about 31.39 Terran years) old

Dependencies:

• Rubygems:
  • chronic

checksums

CLI Ruby script that returns various checksum (MD5, SHAsum, SHA1sum, sha512sum)

Dependencies:

• Commandline tools:
  • md5 and/or md5sum commandline tool
  • shasum and/or sha1sum commandline tool
  • sha512sum commandline tool

convert_units.rb

CLI Ruby script that converts various temperature and other units. Started as a temperature conversion tool to convert degrees Fahrenheit to various other temperature scales and ended up getting a fallback to the ruby-units gem for conversion of various other units.

Dependencies:

• Rubygems:
  • ruby-units

find_larger_than

CLI Bash script that helps you find the large files that are hogging your disk space.

Usage:

find_larger_than MIN_SIZE START_PATH MIN_SIZE supports following suffixes:

• 'b' (512-byte blocks (default))
• 'c' (bytes)
• 'w' (two-byte words)
• 'k' (1024 (kilo) bytes))
• 'M' (1048576 (Mega) bytes)
• 'G' (1073741824 (Giga) bytes) MIN_SIZE defaults to 100M and START_PATH to ~/

Examples:

Find files larger than 200 kilobytes in your bindir and its subdirs:

find_larger_than 200k ~/bin/

Find files larger than 200 megabytes across all your partitions:

sudo find_larger_than 200M /

Find files larger than 100 megabytes in your homedir and its subdirs (the defaults):

find_larger_than

Dependencies:

• find commandline tool.
