In a BASH script I'm writing, I need temporary files. Unfortunately, not only some of the used programs don't accept stdin nor stdout, but they also require "extensions" on the input/output file.
As I want to be sure nothing is overwritten, I tried calling mktemp with a modified template: $ mktemp tmp.XXXXXXXXXX.ext mktemp: too few X's in template `tmp.XXXXXXXXXX.ext' Which is just the default template with some more characters appended, that is, the amount of X's is the same. I even tried with more and more X's and it still didn't work, so I gave up, as the problem must be something else. Is this a limitation of mktemp (X's must be on the right)? Or am I missing some parameter? --suffix=.ext (seen on the web) doesn't work. (And the version is 7.5:) $ mktemp --version mktemp (GNU coreutils) 7.5 Copyright (C) 2009 Free Software Foundation, Inc.
