sh - Find a file that was created within five days of another file in shell -

i'm still pretty new scripting stick me , if have questions please feel free ask.

okay, so: have file let's file.txt

file.txt exists in directory /this/is/the/directory/file.txt

in separate directory .log files exist tell me happens when file.txt created.

fuubar.log, fuu.log, bar.log, this.log, that.log, some.log, other.log...there unknown number of these logs.

i need gather log files occurred +-5 days of file.txt file being created.

for example: file.txt created on 7 july 2013 (don't pay attention date format) need log files occurred on , between 2 july 2013 , 12 july 2013.

any ideas?

edit: i'm more confused comparing dates of files correct ones, know how copy files.

perl , stat not available me

since on qnx can't use existing posix/linux/unix/bsd scripts off shelf in approach this. if either install programming languages can or install updated system utilities (from qnx 1 hope) or shell tools achieve same thing might easier, realize not possible.

you try following horrid hackish approach quick "works now" solution though:

first use find /path/to/log/file.txt -printf %cj give day of year 1-366 in log file created , -printf %cy give year value. next use expr +/- 5 did before find values $day_of_year_start , $day_of_year_end can use set $start , $end variables in jp's script or variation on it.

now need way epoch time use date -s can convert epoch time format touch -t use. without date can convert , epoch time , no strftime outputs epoch time make easy, need "hack". 1 messy approach set constant epoch time @ beginning of year (say 1356998400 jan 1 2013 ; plus values other years if needed) , add ($day_of_year_start x 86400) , ($day_of_year_end x 86400) seconds constant 2 epoch time values run through date -s on qnx , set date/timestamp $start , $end respectively.

messy might work :-) let know if try this.

cheers, ps: here's start of script you'll need check command arguments , date formats qnx make sure correct. works on bsd boxes have gfind (gnu find) , date -r (instead of date -s qnx).

#!/bin/sh # find files created within 5 days before/after # creation of file on qnx. #  #  ./rangesearch /path/to/logfile.txt #  # nb:  # qnx shell environment lacks posix/gnu features: # 1.

'date' cannot modify dates using day/month/year values convert #    epoch values in roundabout way.
