  • Why would you need to create a tar archive? Would it not be eough to just compress it with e.g. gzip? Commented May 5, 2019 at 11:40
  • I need to put multiple files into the archive which is not possible with gzip, but with tar and 7zip it is. Commented May 5, 2019 at 11:56
  • But if the data is coming in over the standard input stream, how would you distinguish the individual files? Or are you adding a file at a time by running the pipeline multiple times? What's the actual command at the start of your pipeline? Commented May 5, 2019 at 12:02

    The actual command is a python script which uses convert and outputs a png to stdout. Yes, I wish to run the command several times, each time specifying a different filename. Commented May 5, 2019 at 12:32
  • How about just writing a shell script which wraps around tar and appends to the tar file? Or create a temporary file yourself. tar cannot append from stdin. Commented May 5, 2019 at 15:09
