When I run the following command: parallel --max-procs 4 echo ::: {1..4}in my PC, it produces the expected output, 1, 2, 3, 4 (in different lines). However, when I run the same command on another computer (which has parallel installed), it doesn't produce output. Both PCs have Ubuntu 14.04 installed (the one where the command works has Ubuntu desktop and the other has Ubuntu server). I know this is a broad question, but what could be the problem??Running echo {1..4} produces output in both computers.Additional info: Running help on the console on both computers (the one where parallel works and the one where it doesn't produce output) gives:GNU bash, version 4.3.11(1)-release (x86_64-pc-linux-gnu)on both computers. Running parallel --version gives:GNU parallel 20130922Copyright (C) 2007,2008,2009,2010,2011,2012,2013 Ole Tange and Free Software Foundation, Inc.License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html>This is free software: you are free to change and redistribute it.GNU parallel comes with no warranty.Web site: http://www.gnu.org/software/parallelWhen using GNU Parallel for a publication please cite:O.

parallel --max-procs 4 echo ::: {1..4} produces no output?
gnu parallel
It turns out that I had zero free disk space on the PC that was giving trouble! Maybe this is too specific, but I am going to leave this here anyway, in case someone else runs into a similar problem.
