RMEXTATTR(8) BSD System Manager's Manual RMEXTATTR(8) NAME getextattr, lsextattr, rmextattr, setextattr -- manipulate extended at- tributes SYNOPSIS getextattr [-fhqsx] attrnamespace attrname filename ... lsextattr [-fhq] attrnamespace filename ... rmextattr [-fhq] attrnamespace attrname filename ... setextattr [-fhnq] attrnamespace attrname attrvalue filename ... setextattr -i [-fhnq] attrnamespace attrname filename ... DESCRIPTION These utilities are user tools to manipulate the named extended at- tributes on files and directories. The attrnamespace argument should be the namespace of the attribute to retrieve: legal values are user and system. The attrname argument should be the name of the attribute, filename the name of the target file or directory, attrvalue a string to store in the attribute. The following options are available: -f (Force.) Ignore errors on individual filenames and continue with the remaining arguments. -h (No follow.) If the file is a symbolic link, perform the opera- tion on the link itself rather than the file that the link points to. -i (From stdin.) Read attribute data from stdin instead of as an argument. -n (NUL-terminate.) NUL-terminate the extent content written out. -q (Quiet.) Do not print out the pathname and suppress error mes- sages. When given twice, print only the attribute value, with no trailing newline. -s (Stringify.) Escape nonprinting characters and put quotes around the output. -x (Hex.) Print the output in hexadecimal.
