Some notes on find and xargs

nguyenduytho — Mon, 04 Jan 2010 07:43:57 +0000

Invoke multiple commands with find

#find ./ -type f -name '*.txt' -exec cmd1 {} \; -exec cmd2 {} \;

Use xargs with file contains spaces

#find ./ -type f |xargs -0  cmd

Replace {} with a name ‘file’

# find ./ -type f |xargs -0 -I file cmd file

Erlang-mode with Emacs on Cygwin

nguyenduytho — Mon, 27 Jul 2009 08:41:00 +0000

Run setup.exe of Cygwin then select the package emacs. Once the install of emacs done, edit your $HOME/.emacs with the following content

(setq load-path (cons “/cygdrive/c/erl/lib/tools-2.6.4/emacs” load-path))
(setq erlang-root-dir “/cygdrive/c/erl”)
(setq exec-path (cons “/cygdrive/c/erl/bin/” exec-path))
(require ‘erlang-start)

where Erlang is installed under c:/erl

Now load your emacs with an erlang source code file.

Rxvt: a better console for win32

nguyenduytho — Fri, 24 Jul 2009 04:13:18 +0000

Using cygwin is a good complement for people used to live with Unix-world but the default DOS-console is terrible. Install rxvt for a better console on Windows. I do the following steps to setup rxvt

Launch your cygwin setup.exe then select the rxvt package.
Create a shortcut on your desktop or your toolbar with

"C:\cygwin\bin\rxvt.exe -display :0 -fn "Monaco-18" -tn rxvt-cygwin-native -e /bin/bash --login"
Edit your $HOME/.Xdefaults

Rxvt.reverseVideo: true Rxvt.saveLines: 2000 Rxvt.font: "Monaco-18" Rxvt.geometry: 85x27
Add the following lines to your $HOME/.inputrc

"\e[3~": delete-char "\e[1~": beginning-of-line "\e[4~": end-of-line "\e[H": beginning-of-line "\e[F": end-of-line "\e[7~": beginning-of-line "\e[8~": end-of-line

You now have a shiny console for your Windows.
