Documentation Parameter references

[thorstenwagner]

Hi,

the page about parameter references references in the beginning to an previous example that does not really exist? At least I couldnt find it?

"In a previous example, we extracted a file using the “tar” program. However, that example was very limited because it assumed that the file we were interested in was called “hello.txt"

A link to the previous example would be helpful.

Best, Thorsten
