This is probably a cheat question (non-central Cygwin issue) but it is about Cygwin's vanilla sed.
AND it is only asked in order eventually to provide anybody interested with the elegant-est possible script for making a portable Cygwin CD. Q1. Querying info sed reveals the expression matcher to be "greedy", matching the longest possible string. Is there a way to make it match the shortest possible, so that echo aaabbbccc | sed 's/^.*b//' (altered but similar) grabs aaab not aaabbb? Q2. Is there a way using the supplied sed without major enhancements to change "abc x def" to "def x abc": that is, to grab two distinct portions and swap them (using $1,$2 or \1,\2 or whatever). Sorry for asking: I know it's a sin: hope the end articulated above justifies the means.
