NAME
pbput - compress and encode arbitrary files to pastebin.com
pbputs - compress, encrypt, encode arbitrary files to pastebin.com
pbget - decode and decompress arbitrary files from pastebin.com
SYNOPSIS
pbput [FILENAME]
cat foo | pbput
pbputs [FILENAME] [GPG_USER]
cat foo | pbputs [GPG_USER]
pbget URL [DIRECTORY]
DESCRIPTION
pbput is a program that can upload text files, binary files or entire directory structures to a pastebin, such as pastebin.com.
pbget is a program that be used to retrieve content uploaded to a pastebin by pbput.
pbputs operates exactly like pbput, except it encrypts the data. An optional GPG_USER argument is allowed, which will sign and encrypt the
data to the target user in one's keyring (which could be oneself!). Otherwise, the user is prompted for a symmetric passphrase for
encrypting the content with gpg(1) before uploading. pbget will automatically prompt the receiving user for the pre-shared passphrase.
pbput and pbputs can take its input either on STDIN, or as a FILENAME argument.
- If STDIN is used, then the receiving user's pbget will simply paste the input on STDOUT.
- If a FILENAME or DIRECTORY is passed as an argument, then it is first archived using tar(1) to preserve the file and directory
attributes
pbget takes a URL as its first, mandatory argument. Optionally, it takes a DIRECTORY as a second parameter. If the incoming data is in
fact a file or file structure in a tar(1) archive, then that data will be extracted in the specified DIRECTORY. If no DIRECTORY is speci-
fied, then a temporary directory is created using mktemp(1).
In any case the uploaded/downloaded data is optionally tar(1) archived, always lzma(1) compressed, optionally gpg(1) encrypted, and always
base64(1) encoded. http://pastebin.com is used by default.
EXAMPLES
$ pbput /sbin/init
http://pastebin.com/BstNzasK
$ pbget http://pastebin.com/BstNzasK
