There are two kinds of regular expressions, "basic" and "extended". sed, ed, and grep speak BRE syntax, whereas awk and egrep speak ERE syntax. + is special only in ERE syntax. (And then there's GNU, where the difference between BRE and ERE is that some things use a preceding backslash in BRE and don't in ERE, and vice versa, so GNU sed does what you want if you use \+ instead of +.) -- brandon s. allbery [linux,solaris,freebsd,perl] allbery_at_kf8nh.com system administrator [WAY too many hats] allbery_at_ece.cmu.edu electrical and computer engineering, carnegie mellon univ.
