Package: grep Version: 3.8-5 PATH_TEST="../../dir/dir/dir/dir/@#$%^&*()-_=+\\|;:'\",<.>/?/"; echo "$PATH_TEST" | grep "^\.\?\.\?\([a-zA-Z0-9@#$%^&*()-_=+\|;:'",<>/?]\+\)\+/\?$";
. is not within the character set portion of the match specification provided to grep. ../../ is matched; I expect it to match only '../', therefore no match for the line. . is also matched in the ,<.> portion toward the end of the path. SOURCE="[[]]"; echo "$SOURCE" | grep "[[]]\+" The very first [ is not matched in this string. grep "[\[\]]\+" does not match it either. Regards, sunny
