I think you're right. Since you are executing this from a .bat file, Windows
doesn't know that the ' character should quote a >. Only Cygwin recognizes
' as a quoting character and by the time cygwin gets the command line, it is
too late because Windows has mangled it.
Can you either change the outer quotes to be ", which Windows does
recognize, or just put everything in a nice shell script and execute it
as "sh foo", i.e.
#/bin/sh
exec awk 'BEGIN {FIELDWIDTHS = "31 8 41"} $1 ~ "^5" {seqid[NR - 2] = $2}
END {for (i = NR - 4; i > 0; i-- ) print seqid[i] }' $1
?
