- quote-get - Displays a random quote from a remote file. The quote stays the same until the following day. The remote file is cached locally for convenience :smiley_cat:

## cloudsurfer.sh
|
||||
`cloudsurfer.sh` is a new script I'm writing to bring some of the customisations I store here in this repository to terminals on shared machines - where I can't modify `.bashrc`, for example.

‘reflac’ recompresses FLAC files while maintaining tags and file names.
|

|

Usage: reflac [OPTION]... [--] DIRECTORY...
|
||||
|
||||
-h --help Displays this help text
|
||||
-V --version Displays the version of this program
|
||||
-v --verbose Increases the verbosity. Use once to display the FLACs
|
||||
currently being processed, use twice for the full ‘flac’
|
||||
output.
|
||||
-r --recursive Recurse into directories.
|
||||
-n --no-action Do not recompress. With --verbose, displays a list of
|
||||
files that would be processed.
|
||||
-p --preserve Preserve file modification time.
|
||||
-s --no-sync Do not synchronize file data. Will return faster, with
|
||||
the potential danger to lose your files in a system crash.
|
||||
-0 --fast Use the fastest, but worst, compression possible.
|
||||
-1..-7 Adjust FLAC compresion between these standard ranges.
|
||||
The default is -5, the same as for flac itself.
|
||||
-8 --best Use the slowest, but best, compression possible.
|
||||
|
||||
DIRECTORY should point ‘reflac’ to somewhere that contains *.flac
|
||||
files. Optionally terminate the argument list with -- so that any
|
||||
possible directory names don’t get misinterpreted as arguments.
