pbputs
pbput(1) bikeshed pbput(1) 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.

$ pbput /sbin/init http://pastebin.com/BstNzasK $ pbget http://pastebin.com/BstNzasK sbin/init INFO: Output is in [/tmp/pbget.bG67DwY6Zl] $ cat /etc/lsb-release | pbput http://pastebin.com/p43gJv6Z $ pbget http://pastebin.com/p43gJv6Z DISTRIB_ID=Ubuntu DISTRIB_RELEASE=11.04 DISTRIB_CODENAME=natty DISTRIB_DESCRIPTION="Ubuntu 11.04" $ pbputs /etc/shadow Enter passphrase: http://pastebin.com/t2ZaCYr3 $ pbget http://pastebin.com/t2ZaCYr3 Enter passphrase: root:09cc6d2d9d63371a425076e217f77698:15096:0:99999:7::: daemon:*:15089:0:99999:7::: bin:*:15089:0:99999:7::: sys:*:15089:0:99999:7::: ....
