Test, validate and match regular expressions
Matches any entire line containing the path /home/virtfs or /net/dba anywhere within it, anchored to line boundaries via the multiline flag. Commonly used in Zenoss monitoring to filter out cPanel's virtual filesystem mounts (/home/virtfs) and autofs/network DBA mounts (/net/dba), which often duplicate underlying storage in filesystem inventories. Applied with global multiline flags to scan logs or command output line by line.
