Find: missing argument to '-exec & #39;, argument-exec

Find: missing argument to '-exec', argument-exec

When you use the find command to find and delete a file today, the following error occurs because a space is required between {} And \. Otherwise, the preceding error is reported. I have not noticed this detail before, so I would like to record it.

 

[Root @ DB-Server full] # find.-maxdepth 1-type d-mtime + 3-exec rm-rf {}\;
Find: missing argument to '-exec'
[Root @ DB-Server full] # find.-maxdepth 1-type d-mtime + 3-exec rm-rf {}\;
