Full Discussion: Delete all files created in specific year
Top Forums UNIX for Beginners Questions & Answers Delete all files created in specific year Post 303036589 by Don Cragun on Wednesday 3rd of July 2019 11:45:09 PM

Note that using:
Code:
find /path/to/files -type f -newermt 2017-01-01 \! -newermt 2018-01-01 -exec rm -fv \{\} \;

will invoke the rm utility once for each of the 200K files you want to remove. That is always going to be relatively slow. If you change that command to:
Code:
find /path/to/files -type f -newermt 2017-01-01 \! -newermt 2018-01-01 -exec rm -fv '{}' +

then the find utility will group together a large number of files to be processed by each invocation of the rm utility and run considerably faster.

And, as stated before but not told how, don't use rm live until you have verified that find is correctly selecting the files you want to process. I would suggest using:
Code:
find /path/to/files -type f -newermt 2017-01-01 \! -newermt 2018-01-01 -exec echo rm -fv '{}' +

first, and, if that produces commands that have correctly identified the files you want to remove, rerun the command without the echo.

shar

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

NAME

     shar -- create a shell archive of files

SYNOPSIS

     shar file ...

DESCRIPTION

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

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

SEE ALSO

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

BUGS

     shar makes no provisions for special types of files or files containing magic characters.

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

HISTORY

     The shar command appears in 4.4BSD.

SECURITY CONSIDERATIONS

     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
