The pattern is composed of the same characters as a glob pattern, but it's treated more like 'grep ^pattern topic' if it doesn't contain any special pattern matching characters. Kind of like the following: $ printf "%s\n" read readonly readarray | grep ^read /dev/stdin read readonly readarray Chet -- ``The lyf so short, the craft so long to lerne.'' - Chaucer ``Ars longa, vita brevis'' - Hippocrates Chet Ramey, ITS, CWRU c...@case.edu http://cnswww.cns.cwru.edu/~chet/
