Check These Out
Shows all block devices in a tree with descruptions of what they are.
Lists out all classes used in all *.html files in the currect directory. usefull for checking if you have left out any style definitions, or accidentally given a different name than you intended. ( I have an ugly habit of accidentally substituting camelCase instead of using under_scores: i would name soemthing counterBox instead of counter_box)
WARNING: assumes you give classnames in between double quotes, and that you apply only one class per element.
if you haven't already done so, install lame and flac:
sudo apt-get install lame flac
To sort hidden files first, simply switch the two inner `ls` commands.
I have this aliased to `dira`
`dir` is aliased to the simpler version with no hidden files:
$ ls -l --color=always | less -R
A bitcoin "brainwallet" is a secret passphrase you carry in your brain.
The Bitcoin Brainwallet Private Key Base58 Encoder is the third of three functions needed to calculate a bitcoin PRIVATE key from your "brainwallet" passphrase.
This base58 encoder uses the obase parameter of the amazing bc utility to convert from ASCII-hex to base58. Tech note: bc inserts line continuation backslashes, but the "read s" command automatically strips them out.
I hope that one day base58 will, like base64, be added to the amazing openssl utility.
Finds all files in the current directory and deletes them besides file called "abc"
Most distributions alias cp to 'cp -i', which means when you attempt to copy into a directory that already contains the file, cp will prompt to overwrite. A great default to have, but when you mean to overwrite thousands of files, you don't want to sit there hitting [y] then [enter] thousands of times.
Enter the backslash. It runs the command unaliased, so as in the example, cp will happily overwrite existing files much in the way mv works.
-R, -r, --recursive
Read all files under each directory, recursively; this is equivalent to the -d recurse option.
