All words of the filenames except "a", "of", "that" and "to" are capitalized.
To also match words which begin with a specific string, you can use this:
rename 's/\b((?!hello\b|t)[a-z]+)/\u$1/g' *
This will capitalize all words except "hello" and words beginning with "t".
Anyone know how to avoid title casing some words, like 'to', 'of', 'that', etc.?
Just a quick hack to give reasonable filenames to TrueType and OpenType fonts.
I'd accumulated a big bunch of bizarrely and inconsistently named font files in my ~/.fonts directory. I wanted to copy some, but not all, of them over to my new machine, but I had no idea what many of them were. This script renames .ttf files based on the name embedded inside the font. It will also work for .otf files, but make sure you change the mv part so it gives them the proper extension.
REQUIREMENTS: Bash (for extended pattern globbing), showttf (Debian has it in the fontforge-extras package), GNU grep (for context), and rev (because it's hilarious).
BUGS: Well, like I said, this is a quick hack. It grew piece by piece on the command line. I only needed to do this once and spent hardly any time on it, so it's a bit goofy. For example, I find 'rev | cut -f1 | rev' pleasantly amusing --- it seems so clearly wrong, and yet it works to print the last argument. I think flexibility in expressiveness like this is part of the beauty of Unix shell scripting. One-off tasks can be be written quickly, built-up as a person is "thinking aloud" at the command line. That's why Unix is such a huge boost to productivity: it allows each person to think their own way instead of enforcing some "right way".
On a tangent: One of the things I wish commandlinefu would show is the command line HISTORY of the person as they developed the script. I think it's that conversation between programmer and computer, as the pipeline is built piece-by-piece, that is the more valuable lesson than any canned script.
This command is useful for renaming a clipart, pic gallery or your photo collection. It will only change the big caps to small ones (on the extension).
The simplest way I know.
Use 'mmv' for mass renames. The globbing syntax is intuitive.
Replace 'SHOWNAME' with the name of the TV show.
Add -n to test the command without renaming files.
Check the 'sample output'.
Best to try first with -n flag, to preview
Useful if non-ascii characters in filenames have been improperly encoded. Replace "PROBLEM" with the incorrect characters (e.g. 'é'), and "FIX" with the correct ones (e.g. '?').
A powerfull way to rename file using sed groups.
& stand for the matched expression.
\1 referes to the first group between parenthesis. \2 to the second.
