The full specification for the AWK language is 40 pages in the book written by the authors. I sometimes forget the exact syntax for pipes and file open/close, but it's not hard to find in 40 pages. AWK is in busybox, and a lot of other places that Python simply cannot go. The control structure syntax is also the same a C/JavaScript/PHP/C++ etc., so it certainly does not hurt to know it. https://archive.org/download/pdfy-MgN0H1joIoDVoIC7/The_AWK_Programming_Language.pdf https://archive.org/download/pdfy-MgN0H1joIoDVoIC7/The_AWK_P...
