Useful scripts

This is a collection of scripts that I find useful but are not worthy of having their own repository each.

256colors

Prints out the xterm 256 color chart.

git-alias

Prints git aliases. The name argument can be used to filter the results.

$ git alias
co      checkout
diffc   diff --cached
diffw   diff --color-words
k       !sh -c 'gitk "$@" &' git-k

$ git alias k
k       !sh -c 'gitk "$@" &' git-k

git-recent-branches

Lists branches and their ages, sorted by last commit timestamp.

$ git recent-branches
  feature                        3 weeks ago
  other-branch                   4 days ago
* master                         8 minutes ago

git-reparent

This is a symlink to git-reparent, assuming it is contained in the same parent directory.

git-sed

Similar to git grep, git sed runs sed on the files generated by git ls-files. This way, you can do something like

git sed -i 's/foo/bar/g'

without having to list files explicitly.

Requires GNU sed since it uses long options.

git-zmv / git-mmv

Uses zsh's zmv module with git mv. For example, to rename all ".markdown" extensions to ".md", use one of the following:

$ git zmv '(*).markdown' '$1.md'
$ git mmv '*.markdown' '*.md'

gping

Simple graphical wrapper around ping.

$ ./gping 192.168.1.1
   1    4 ms +
   2    3 ms +
   3    7 ms +
   4  102 ms +++++++++++
   5  445 ms +++++++++++++++++++++++++++++++++++++++++++++
   6    3 ms +
   7         dropped
   8         dropped
   9    5 ms +

parsetime

Parse a human-readable time and print it in normalized form, including POSIX timestamp (or any other format). Can also be used to convert timezones.

$ parsetime now
Thu 2015-04-30 00:31:46 -0400 EDT (1430368306)
$ parsetime apr 1 2015 pdt
Wed 2015-04-01 00:00:00 -0700 PDT (1427871600)
$ parsetime 1427871600 -f '%c %z' -z EDT
Wed Apr  1 03:00:00 2015 -0400

pithos-control

A script to control Pithos. This is easier to use than raw dbus-send, and it also includes discrete play and pause commands, which are not available directly via dbus. Examples:

$ pithos-control play
$ pithos-control skip

I originally wrote this for use with LIRC, as described in my blog post.

risk

Prints the number of armies needed to perform a march in the game of Risk. For example, to compute the number of armies to safely attack three countries, one occupied by two defenders and two occupied by one each:

$ risk 2 1 1
Total armies expected needed: 11.5781570709 + extra for safety

Defender      Loss  Inc. Loss  (not counting 2 army to occupy)
========  ========  =========
       2  1.546578   1.030789
       1  0.515789   0.515789
       1  0.515789   0.515789
