-# Examples
-
-## File flags
-Show open files with file flags for process:
-```markdown
-lsof +fg -p <pid>
-```
-
-## Open TCP connections
-Show open tcp connections for `$USER`:
-```markdown
-lsof -a -u $USER -i TCP
-```
-**Note**: `-a` _ands_ the results. If `-a` is not given all open files matching
-`$USER` and all tcp connections are listed (_ored_).
-
-## Open connection to specific host
-Show open connections to `localhost` for `$USER`:
-```markdown
-lsof -a -u $USER -i @localhost
-```
-
-## Open connection to specific port
-Show open connections to port `:1234` for `$USER`:
-```markdown
-lsof -a -u $USER -i :1234
-```
-
-## IPv4 TCP connections in `ESTABLISHED` state
-```markdown
-lsof -i 4TCP -s TCP:ESTABLISHED
-```
-## List open files in a mounted directory.
-This may help to find which processes keep devices busy when trying to unmount
-and the device is currently busy.
-```markdown
-# Assuming /proc is a mount point.
-lsof /proc
-```
