Мутаген,

chown права портит:

donner-gms,

find PATH CRITERIA | while read line; do mode=`stat --format=%a "$line"`; chown NEWUSER "$line"; chmod $mode "$line"; done

МутагенСейчас проверил на Solaris 10, не сносит там родной chown suid bit.
Ну и stat в комплекте десятой версии нету.по этому поводу посикс пищет так:POSIXIf the specified file is a regular file, one or more of the S_IXUSR, S_IXGRP, or S_IXOTH bits of the file mode are set, and the process does not have appropriate privileges, the set-user-ID (S_ISUID) and set-group-ID (S_ISGID) bits of the file mode shall be cleared upon successful return from chown(). If the specified file is a regular file, one or more of the S_IXUSR, S_IXGRP, or S_IXOTH bits of the file mode are set, and the process has appropriate privileges, it is implementation-defined whether the set-user-ID and set-group-ID bits are altered. If the chown() function is successfully invoked on a file that is not a regular file and one or more of the S_IXUSR, S_IXGRP, or S_IXOTH bits of the file mode are set, the set-user-ID and set-group-ID bits may be cleared.У HP-UX "implementation-defined" поведение chown описано точно, в опенсорсном Linux вообще ни слова про срезание битов.
