DESCRIPTION
|
||
|
|
Upload data and fetch URL from the pastebin http://sprunge.us
|
||
|
|
|
||
|
|
USAGE
|
||
|
|
$0 filename.txt
|
||
|
|
$0 text string
|
||
|
|
$0 < filename.txt
|
||
|
|
piped_data | $0
|
||
|
|
|
||
|
|
NOTES
|
||
|
|
Input Methods:
|
||
|
|
$0 can accept piped data, STDIN redirection [< filename.txt], text strings following the command as arguments, or filenames as arguments. Only one of these methods can be used at a time, so please see the note on precedence. Also, note that using a pipe or STDIN redirection will treat tabs as spaces, or disregard them entirely (if they appear at the beginning of a line). So I suggest using a filename as an argument if tabs are important either to the function or readability of the code.
|
||
|
|
|
||
|
|
Precedence:
|
||
|
|
STDIN redirection has precedence, then piped input, then a filename as an argument, and finally text strings as arguments. For example:
|
||
|
|
|
||
|
|
echo piped | $0 arguments.txt < stdin_redirection.txt
|
||
|
|
|
||
|
|
In this example, the contents of file_as_stdin_redirection.txt would be uploaded. Both the piped_text and the file_as_argument.txt are ignored. If there is piped input and arguments, the arguments will be ignored, and the piped input uploaded.
|
||
|
|
|
||
|
|
Filenames:
|
||
|
|
If a filename is misspelled or doesn't have the necessary path description, it will NOT generate an error, but will instead treat it as a text string and upload it.
