This collection of command-line odds and ends was put together by Adrian Smith, mostly in 1988. They are written in Zortech C, and pre-date all known viruses, so they should be safe to run. Check them anyway!
This is what you have - they all have built-in help:
say.exe 10429 ... coloured text from prompts
bb.exe 12892 ... batch build from file list
cat.exe 14938 ... catenate files, optionally in PostScript
qd.exe 13940 ... like DIR only prettier
ss.exe 14388 ... fast string search, like grep only simpler
ty.exe 14488 ... type files, optionally in hex
wc.exe 10776 ... count words, lines, chars
