Top Forums Shell Programming and Scripting Shellscript command to remove files starting with a certain string, and older than 3 days Post 302969936 by jim mcnamara on Wednesday 30th of March 2016 10:24:21 AM

older than 3 days.
The timestamp on a file is the number of seconds since Jan 1 1970. It gets turned into human readable dates using rules in your locale. So, simply subtracting three days from right now may not be what you want - calendar days, not 86400 seconds * 3. One day is 86400 seconds.

Try this: where I am it is Mar 30, 2016
so second "0" of Mar 29 is the cutoff

Code:
cd /path/to/files
touch -t 201603290000 dummy

Two options:
1. just the current directory
Code:
for f in prefix*
do
     if  [ "$f" -ot dummy ] ; then
       rm $f
     fi
done

2. whole directory tree starting from current directory

Code:
find . -type -name 'prefix*'  ! -newer dummy -exec rm {} \;

Name
       uuclean - uucp spool directory clean-up

Syntax
       uuclean -p[pre] [ options ... ]

Description
       The  command  scans the spool directory for files with the specified prefix and deletes all those which are older than the specified number
       of hours.

       The -ppre argument causes the command to scan for files with pre as the file prefix.  You can specify up to 10 arguments.   A  without  any
       pre following causes all files older than the specified time to be deleted.  You must specify at least one argument.

Options
       -ntime	    Delete  all  files	whose age is more than time, in hours, (default is 72 hours) and that have the specified pre as their file
		    prefix.

       -m	    Send mail to the owner of the file when it is deleted.

       -ssystem     Delete files in all directories that are subdirectories of the per system spool directory that exists for system.  If  ALL	is
		    specified, then all system directories are processed.  ALL is the default.

       -ddirectory  Delete files that reside in the named directory.  The default directory is The option over rides the option.

       The  command typically starts the program.  In earlier versions, a deleted work file (C.file) would result in mail to the owner of the work
       file, regardless of the option.	Now, notification of deleted work files is sent to the user ID "uucp".	If the option  is  used,  mail	is
       also sent to the owner.

Examples
       Here are some example command lines:
       # uuclean -pLTMP. -pLOG. -n4 -d/usr/spool/uucp
       # uuclean -d/usr/spool/uucp/.XQTDIR -p -n
       # uuclean -smarkie -p -n84
       The third example deletes all files for the system that are older than 84 hours.

Files
       Directory with commands used by uuclean internally
