lsattr - list file attributes on a Linux second extended file system
lsattr [ -RVadv ] [ files... ]
lsattr lists the file attributes on a second extended file system. See chattr(1) for a description of the attributes and what they mean.
-R Recursively list attributes of directories and their contents. -V Display the program version. -a List all files in directories, including files that start with `.'. -d List directories like other files, rather than listing their contents. -v List the file's version/generation number.
