Nothing says that the other process that removed, moved, or deleted that file was being run by another find command nor that it had been started by cron. Anybody logged on to your network with write access to the directory in question could remove a file. And, by the time you see the error message, that process could already be gone. There might not be a running process left to find. If you have process accounting running, you might be able to find who was running another process at the time find reported the error.

Of course if you were running the two copies of the same script at the same time, you could easily see several errors like that as they fight with each other trying to be the first one to find and process the selected files. But, if you have only seen this once, it is more likely that someone manually removed a file while your cron job was running.

shar

SHAR(1) 						    BSD General Commands Manual 						   SHAR(1)

NAME

     shar -- create a shell archive of files

SYNOPSIS

     shar file ...

DESCRIPTION

     The shar command writes a sh(1) shell script to the standard output which will recreate the file hierarchy specified by the command line op-
     erands.  Directories will be recreated and must be specified before the files they contain (the find(1) utility does this correctly).

     The shar command is normally used for distributing files by ftp(1) or mail(1).

EXAMPLES

     To create a shell archive of the program ls(1) and mail it to Rick:

	   cd ls
	   shar `find . -print` | mail -s "ls source" rick

     To recreate the program directory:

	   mkdir ls
	   cd ls
	   ...
	   <delete header lines and examine mailed archive>
	   ...
	   sh archive

SEE ALSO

     compress(1), mail(1), tar(1), uuencode(1)

HISTORY

     The shar command appeared in 4.4BSD.

BUGS

     The shar command makes no provisions for special types of files or files containing magic characters.  The shar command cannot handle files
     without a newline ('
') as the last character.

     It is easy to insert trojan horses into shar files.  It is strongly recommended that all shell archive files be examined before running them
     through sh(1).  Archives produced using this implementation of shar may be easily examined with the command:

	   egrep -v '^[X#]' shar.file
