(SVN) Howto list all the file extension types in an SVN log dump

Thu, 11 Feb 2010 14:59:31 GMT

Note that on Windows you will want to double-quote the string argument to `perl -ne` rather than single-quoting it. Otherwise this works on Windows (with Cygwin) as well.

(Perl) grep with Perl

Thu, 05 Feb 2009 13:29:59 GMT

A combination of the instructions in the book _Minimal Perl_ and [this Perl one-liners page](http://sial.org/howto/perl/one-liner/) The general form of the one-liner is: > perl -wnl -e '/REGEX/ and print $ARGV." $.: $_"; close ARGV if eof' The example below shows how to print the hex colors that are defined in a [Sass](http://haml.hamptoncatlin.com/docs/rdoc/classes/Sass.html) source tree.

This one-liner counts how many of the links to onemorebug.com there are on http://delicous.com/tag/noahsussman. Basically it prints a number, and that number is the percentage of the top 100 links for that tag in delicious that point to your URL. Requires Grep, Lynx and Wc.

(Bash) Exclude some directories from grep

The following command will grep for a string in HTML files, but will skip the directories dirFoo and dirBar. (Thanks Jeff)

(Bash) Find/Grep for a string across multiple files with different extensions

Sun, 28 Jan 2007 07:43:53 GMT

Search many files for a string. This example finds the string "thingy." This is useful when I want to find, say, a CSS class name that has changed, and update it in all of my .js, .jsp and .jspf files. The -niP argument to grep is optional. -n prints line numbers, -i makes search case-insensitive, and -P toggles Perl regular expression syntax. (I'm not sure that -P works under Cygwin.)
