Top Forums Shell Programming and Scripting How to select all files added to a directory in the past 5 mins (HP-UX)? Post 302935502 by rbatte1 on Tuesday 17th of February 2015 06:31:59 AM

I would use perl too, but to get the required start time. We can then create a reference file and use find based on that to select files.

Assuming you can't just use "date +%s", something like:-
Code:
#!/bin/ksh


date '+%Y %m %d %H %M %S' | read in_Y in_m in_d in_H in_M in_S                                   # Get current time values 
((in_m=$in_m-1))                                                                                 # Reduce month by one as epoch counts from 1/1/1970 as month zero

perl -e "use Time::Local; print timelocal($in_S,$in_M,$in_H,$in_d,$in_m,$in_Y), ;" | read cur_S  # Get current time in seconds since epoch
((old_S=$cur_S-300))                                                                             # Go back five minutes (in seconds)

perl -e 'use POSIX qw(strftime);\
print scalar(strftime "%Y %m %d %H %M %S", localtime $ARGV[0]), "\n";' $old_S | read Y m d H M S # Display answer in required format to be read in

touch -mt ${Y}${m}${d}${H}${M}.${S} /tmp/ref_file                                                # Create reference file

find . -type f -newer /tmp/ref_file                                                              # Find required files

It's a bit messy, but I hope you can see what is being done and why.


Does this help?

This module provides routines to format dates. They correspond to the libc routines. &strftime() supports a pretty good set of coversions -- more than most C libraries. strftime supports a pretty good set of conversions. The POSIX module has very similar functionality. You should consider using it instead if you do not have allergic reactions to system libraries. GENESIS
