So the second pattern matches any line that contains a *literal* 's' followed by zero or more control chars, which is any line because of the newline at the end which is a control char. Since you did not ask for perl regex (-P) grep uses basic POSIX regex instead; at least I *think* you want perl syntax given that '\s' is only valid in PCRE, IIRC. Also [:cntrl:] is not the correct char class for white space, why not [:space:] or [:blank:]? Your first pattern just happens to match the literal space in it *and* any following string of zero or more control chars.

Turns out that last part is not true, sorry. I was going by the grep(1) man page instead of `info grep`, which does say that '\s' is shorthand for '[[:space:]]'. Still, the 2nd pattern is incorrect. IIUC this is what it should look like: # '-i' is bogus since there is no upper/lower case whitespace grep --color=never -sHn '[[:blank:]][[:cntrl:]]*$' [:blank:] is the more correct char class because '\s' matches anything in the ASCII range 0-31 (plus [127]) and as it so happens is in that range. DOS files have the in front of (a.k.a. '$'), which is why the original pattern did match *correctly*. Contrary to the claim in the OP I could only reproduce the "false" behavior with DOS and not UNIX files. And now I understand why '[[:cntrl:]]' is in the pattern (sorry for my initial misunderstanding). DOS, the gift that keeps on giving. :P Also note the '--color=never'. I don't know how relevant this is on Windows but on my terminal emulator (with --color=auto) the at the end of a line in DOS files would be printed as a match and the terminal obeyed with all the ensuing consequences, leaving empty lines without match text. Another "gift", I guess.

IIRC even Cygwin dropped Windows text handling in coreutils, findutils, grep, sed, etc. about 2018 to be consistent with other POSIX platforms. Use d2u/dos2unix or u2d/unix2dos in pipes to convert, or equivalent, such as tr -d '\r', sed -e 's/\r//g', awk -e '{gsub(/\r/,"")'. Cygwin users may be able to compensate by remounting the filesystem with a "text" mount option -o text or the equivalent in an /etc/fstab entry, but I am unsure if anyone has tested using that option nowadays. -- Take care.
