Chnorm is a simple command line utility for setting the owner, group, and the mode of given files and directories on a per file/per directory basis, recursively. It is especially useful if you often copy files with brain-dead permissions from filesystems not supporting the Unix permission scheme. It detects executables based on their contents and sets their permissions accordingly.
fswalker is an indexer and query tool for large filesystems. On large filesystems it is impossible to run tools such as du and obtain results in a reasonable time. fswalker crawls over a filesystem and populates a SQLite database containing information about each file. The fsq utility can then be used to query the database and obtain information much faster. It is intended that fswalk be run in a periodic manner so the sysadmin can monitor changes in the filesystem and produce reports.
