Setting the sticky bit on world writable directories prevents users from deleting or renaming files in that directory that are not owned by them.
This feature prevents the ability to delete or rename files in world writable directories (such as /tmp) that are owned by another user.
df --local -P | awk {'if (NR!=1) print $6'} | xargs -I '{}' find '{}' -xdev -type d \( -perm -0002 -a ! -perm -1000 \) 2>/dev/null
No output should be returned. If any directories are listed, the sticky bit is not set on them.
df --local -P | awk {'if (NR!=1) print $6'} | xargs -I '{}' find '{}' -xdev -type d -perm -0002 2>/dev/null | xargs chmod a+t
By default, the sticky bit is set on /tmp but may not be set on other world-writable directories.
