  • Hey Bruno! I am actually interested in doing in non-bash situations. Essentially interested in running a single command using variables. In the current case, due to limitations, I cannot use a bash script, solely the commands. Commented Mar 30, 2017 at 13:57
  • You know, this answer be a lot more useful if it didn't rely on only the link but e.g. gave an example relevant to this situation. Answers with only links also have the risk that the link will rot, making the answer pretty much useless. Commented Mar 30, 2017 at 14:12
  • @ilkkachu You are generally right, but I suspect that tldp.org will outlive the SO stack (it is official documentation, not some blog). I also think that OP need to be pointed to some quality bash documentation. Commented Mar 30, 2017 at 14:22
  • @Bruno9779, I was under the impression that as a GNU program, Bash's official documentation would be maintained by the GNU project. In any case, a document from 2000 might not be the best reference, and this answer does not contain the actual answer, just a pointer. Commented Mar 30, 2017 at 14:31
