File Flags Metadata

chflags(2) (st_flags) metadata support. Per-file settable attributes. Typically implemented on BSD platforms.

Metadata supported

For platforms that support them:

• User No Dump
• User Immutable
• User Append
• User Opaque
• System Archived
• System Immutable

Implementation status

Implemented since repository revision 92 (2007-01-29).

Notes

• Note that some flags have overlap and may be duplicated with other metadata support. Most notably this happens with Linux EXT2 file attributes.
• Archival of flags is implemented using the st_flags struct member of the stat metadata on platforms that support it.
• Extraction of flags is implemented using the chflags(2) APIs on platforms that support it.
