  • in other words, EOF in this context means an end-of-file marker, not the actual end of the script file. the text "EOF" is any arbitrary text - whatever you use immediately after the << characters will indicate the end of the here-now document. I typically use EOF because it stands out and is very unlikely to be inside the herenow document if, e.g., i'm programatically-generating the shell script (which i do quite often).

  • Using here-documents like this, I have often changed the ending marker to something much more meaningful (and less likely to be "randomly" matched), like END_OF_WHATEVER_FUNCTION. Sometimes, trying to "save" space/size is actually a waste of effort because it causes ambiguity as to what is actually happening. Commented Jul 8, 2012 at 16:51
