What is the Significance of '{}' \; in UNIX?
You can read about that with "man find" and -exec option.
FIND-BASED:
{} is used for passing find output to exec as an argument.
; is for terminating the exec part ; its escaped by \ so that bash ignore it or bash would take is as an subsequent command.
example
find /usr -name lib -print -exec ls -l {} \;
