How can I pastebin 2 commands?

Question

When I try to pastebin 2 command like this:

echo Merry && echo Christmas | pastebinit

It only pastebins the second command, and gives the first as output:

Merry
http://paste.ubuntu.com/9605648/

Now I could just do:

echo Merry Christmas | pastebinit

And that would work, but I want to run 2 separate commands, and pipe the output to pastebinit, I can't:

sudo apt-get install christmas && sudo apt-get update | pastebinit

does not seem to work.

Does `sudo apt-get install christmas && sudo apt-get update | tee output.txt && pastebinit -f output.txt` work? — Seth, Dec 23 '14 at 19:50
That's what I was afraid of.. Muru's solution seems to work though! — Seth, Dec 23 '14 at 20:27
Yes, and I believe your command just made my computer hang :p could have been coincidence, but the command never ended, I forgot to stop it and then I had to force restart... — Tim, Dec 23 '14 at 20:36

Wrap it to make a compound command:

{ echo Merry && echo Christmas;} | pastebinit

In general, to pipe the output of multiple commands in sequence to another command, do:

{ cmd1; cmd2; ...;} | cmd

or

(cmd1; ... ) | cmd

@Tim As I understand it, for the case of pipes, no. Braces are usually used to run commands in the current shell and parentheses for running in a subshell, but pipes force the usage of a subshell anyway. But I could be wrong. It looks like a good question for [unix.se]. – muru Dec 23 '14 at 20:22

Okay - I believe that edit is needed btw. – Tim Dec 23 '14 at 20:23

Is there a reason you couldn't first redirect the output of the two commands into a file (using append for the output of the second command), and then pipe that to pastebinit?

echo Merry > out.txt && echo Christmas >> out.txt && cat out.txt | pastebinit

Maybe redirect stderr to the out file also.

If you're going to `cat` anyway, avoid manually creating a file: `cat <(echo Merry) <(echo Christmas) | pastebinit` – muru Dec 24 '14 at 06:09
OP doesn't want the second command executed if the first one returns an error condition. Unfortunately, your edit omits that requirement. Perhaps this: cat <(echo Merry && echo Christmas) | pastebinit – Stephen Davison Dec 24 '14 at 21:30

Here follows a work-around to answer the question of "how do I grab complex output on the CLI?"

Should be useful:

thufir@dur:~$ 
thufir@dur:~$ script xmas
Script started, file is xmas
thufir@dur:~$ 
thufir@dur:~$ echo Merry && echo Christmas
Merry
Christmas
thufir@dur:~$ 
thufir@dur:~$ exit
exit
Script done, file is xmas
thufir@dur:~$ 
thufir@dur:~$ cat xmas 
Script started on 2017-10-27 06:37:59-0700
thufir@dur:~$ 
thufir@dur:~$ echo Merry && echo Christmas
Merry
Christmas
thufir@dur:~$ 
thufir@dur:~$ exit
exit

Script done on 2017-10-27 06:38:23-0700
thufir@dur:~$ 
thufir@dur:~$ pastebinit xmas
http://paste.ubuntu.com/25830406/
thufir@dur:~$

Here's the pastebin file on ubuntu, as above. Reference man script for how to use typescript.

Note that you can execute scripts, interact, etc. The script command just logs everything into a file. Not quite sure how to make it more readable without futzing with the console/shell configuration...

Basically, if you turn off all colors, etc, it looks better.
