diff two css files to create an overriding css (e.g. for wordpress child themes)

This will extract the differing CSS entries of two files. I've left the initial character (plus or space) in output to show the real differing line, remove the initial character to get a working CSS file. The output CSS file is usable by either adding it in a below the to original.css, or by only using the output but adding @import url("original.css"); in the beginning.

This is very useful for converting Wordpress theme copies into real Wordpress child themes.

Could exclude common lines within entries too, I guess, but that might not be worth the complexity.

for f in $(ls -A ./dir); do echo -n $f && diff original.txt ./dir/$f | wc -l ; done | perl -ne 'my $h={}; while (<>) { chomp; if (/^(\S+?)\s*(\d+?)$/){$h->{$1}=$2;} }; for my $k (sort { $h->{$a} $h->{$b} } keys %$h ){ print "$k\t$h->{$k}\n"}'

Probably, most frequent use of diff

This form is used in patches, svn, git etc. And I've created an alias for it:

alias diff='diff -Naur --strip-trailing-cr'

The latter option is especially useful, when somebody in team works in Windows; could be also used in commands like

svn diff --diff-cmd 'diff --strip-trailing-cr'...

svn diff --diff-cmd="colordiff"

svn diff colorized

If colordiff utility installed, it is sometimes handy to call this command. Of course, you should create an alias for it. E.g. svndiff.

diff files while disregarding indentation and trailing white space

**NOTE** Tekhne's alternative is much more succinct and its output conforms to the files actual contents rather than with white space removed

My command on the other hand uses bash process substitution (and "Minimal" Perl), instead of files, to first remove leading and trailing white space from lines, before diff'ing the streams. Very useful when differences in indentation, such as in programming source code files, may be irrelevant
