How to use pastebin from shell script? - http

Question

Is it possible to use pastebin (may be via their "API" functionality) inside bash shell scripts? How do I send http-post? How do I get back the URL?

Answer 1

As pastebin.com closed their public api, I was looking for alternatives.
Sprunge is great. Usage:
<command> | curl -F 'sprunge=<-' http://sprunge.us
or, as I use it:
alias paste="curl -F 'sprunge=<-' http://sprunge.us"
<command> | paste

Answer 2

The documentation says that you need to submit a POST request to
http://pastebin.com/api_public.php
and the only mandatory parameter is paste_code, of type string is the paste that you want to make.
On success a new pastebin URL will be returned.
You can easily do this from your bash shell using the command curl.
curl uses the -d option to send the POST data to the specified URL.
Demo:
This demo will create a new paste with the code:
printf("Hello..I am Codaddict");
From your shell:
$ curl -d 'paste_code=printf("Hello..I am Codaddict");' 'http://pastebin.com/api_public.php'
http://pastebin.com/598VLDZp
$
Now if you see the URL http://pastebin.com/598VLDZp, you'll see my paste :)
Alternatively you can do it using the wget command which uses the option --post-data to sent POST values.
I've tried this command it works fine:
wget --post-data 'paste_code=printf("Hello..I am Codaddict");' 'http://pastebin.com/api_public.php'

Put the following in your .bashrc:
sprunge() {
if [[ $1 ]]; then
curl -F 'sprunge=<-' "http://sprunge.us" <"$1"
else
curl -F 'sprunge=<-' "http://sprunge.us"
fi
}
...and then you can run:
sprunge filename # post file to sprunge
...or...
some_command | sprunge # pipe output to sprunge

Answer 4

The API for posting to pastebin has changed, since posted by codaddict.
Details can be found at this link: https://pastebin.com/api
Example:
curl -d 'api_paste_code=printf("Hello..\n I am Codaddict");' \
-d 'api_dev_key=<get_your_own>' \
-d 'api_option=paste' 'http://pastebin.com/api/api_post.php'
There are three essential fields as of now:
api_dev_key -> You need to create a login on pastebin.com in order to get that
api_option -> Format in which to post
api_paste_code -> Text you want to post

Answer 5

Two other answers (from circa 2014) point to http://sprunge.us, which is designed to be used like this...
curl --form 'sprunge=#yourfile.txt' sprunge.us
However, as of 2018, sprunge.us has a tendency to be overloaded and return 500 Internal Server Error to every request. For files up to at least 300 KB but not as high as 2.8 MB, I have had good luck with the very similar service at http://ix.io:
curl --form 'f:1=#yourfile.txt' ix.io
For files up to at least 2.8 MB (and maybe higher, I don't know), I've found the more highly polished https://transfer.sh. It recommends a slightly different and simpler command line, and requires https (it won't work without it):
curl --upload-file yourfile.txt https://transfer.sh

Answer 6

I have found that Sprunge is currently down, but dpaste.com has a simple API.
To post from STDIN
curl -s -F "content=<-" http://dpaste.com/api/v2/
from a file foo.txt
cat foo.txt | curl -s -F "content=<-" http://dpaste.com/api/v2/
to post a string
curl -s -F "content=string" http://dpaste.com/api/v2/
The response will be a plain text URL to the paste.
Nb: the trailing / in the URL http://dpaste.com/api/v2/ seems necessary

Answer 7

https://paste.c-net.org/ has a simpler API than all of them. Simply "POST" to it.
From the website:
Upload text using curl:
$ curl -s --data 'Hello World!' 'https://paste.c-net.org/'
Upload text using wget:
$ wget --quiet -O- --post-data='Hello World!' 'https://paste.c-net.org/'
Upload a file using curl:
$ curl --upload-file #'/tmp/file' 'https://paste.c-net.org/'
Upload a file using wget:
$ wget --quiet -O- --post-file='/tmp/file' 'https://paste.c-net.org/'
Upload the output of a command or script using curl:
$ ls / | curl --upload-file - 'https://paste.c-net.org/'
$ ./bin/hello_world | curl -s --data-binary #- 'https://paste.c-net.org/'
You can also simply use netcat. Unlike termbin, paste.c-net.org won't time out if your script takes more than 5 seconds to produce its output.
$ { sleep 10; ls /; } | nc termbin.com 9999
$ { sleep 10; ls /; } | nc paste.c-net.org 9999

Answer 8

Easiest way to post to pastebin
echo 'your message' | sed '1s/^/api_paste_code=/g' | sed 's/$/\%0A/g' | curl -d #- -d 'api_dev_key=<your_api_key>' -d 'api_option=paste' 'http://pastebin.com/api/api_post.php'
Just change the <your_api_key> part and pipe whatever you want into it.
The sed invocations add the api_paste_code parameter to beginning of the message and add a newline at the end of each line so it can handle multiline input. The #- tells curl to read from stdin.
A Bash Function You Can Paste
For easy reuse, make it a bash function (copy and paste this into your terminal and set the API_KEY field appropriately:
pastebin () {
API_KEY='<your_api_key>'
if [ -z $1 ]
then
cat - | sed '1s/^/api_paste_code=/g' | sed 's/$/\%0A/g' | curl -d #- -d 'api_dev_key='"$API_KEY"'' -d 'api_option=paste' 'http://pastebin.com/api/api_post.php'
else
echo "$1" | sed '1s/^/api_paste_code=/g' | sed 's/$/\%0A/g' | curl -d #- -d 'api_dev_key='"$API_KEY"'' -d 'api_option=paste' 'http://pastebin.com/api/api_post.php'
fi
printf '\n'
}
You can run it with either:
pastebin 'your message'
or if you need to pipe a file into it:
cat your_file.txt | pastebin

Answer 9

To built upon Vishal's answer, pastebin has upgraded to only use HTTPS now:
curl -d 'api_paste_code=printf("Hello World");' \
-d 'api_dev_key=<your_key>' \
-d 'api_option=paste' 'https://pastebin.com/api/api_post.php'
You don't have to specify the -X POST parameter

Answer 10

Based on another answer on this page, I wrote the following script which reads from STDIN (or assumes output it piped into it).
This version allows for arbitrary data which is URI escaped (by jq).
#!/bin/bash
api_key=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
curl -d "api_paste_code=$(jq -sRr #uri)" \
-d "api_dev_key=$api_key" \
-d 'api_option=paste' 'https://pastebin.com/api/api_post.php'
echo # By default, there's no newline

I am a bit late to this post, but I created a little tool to help with this.
