script to view files based on date
I have a UNIX box where in files are created every 5 minutes. I need to write a shell script which will take in the date as parameter and return me all files created on that day. Also I will like it to show me only files which have a size greater than 0 i.e. non-empty files. how do I go abt this? I am new to UNIX
Thanks in advance, Rahul

Here is a script for you.
Code:
#! /bin/sh # krah.sh [ -z $1 ] && echo "Defaulting to $(date +%F)" && DATE=$(date +%F) || DATE="$1" touch -d "$1" /tmp/OLD touch -r /tmp/OLD -F 86400 /tmp/NEW find . -name '*' -newer /tmp/OLD ! -newer /tmp/NEW ! -size 0 rm -f /tmp/OLD /tmp/NEW Code:

In short RTFM.
From man touch Code:
-d, --date=STRING
parse STRING and use it instead of current time
-F, --forward=SECONDS
Modify the time by going forward SECONDS seconds. For example,
touch -r foo -F 5 bar will make the file bar 5 seconds newer
than file foo.
-r, --reference=FILE
use this file's times instead of current time
And then create /tmp/NEW which is exactly 24 hours newer compared to /tmp/OLD And from man find, Code:
-newer file
File was modified more recently than file. -newer is affected
by -follow only if -follow comes before -newer on the command
line.
-size n[bckw]
File uses n units of space. The units are 512-byte blocks by
default or if `b' follows n, bytes if `c' follows n, kilobytes
if `k' follows n, or 2-byte words if `w' follows n. The size
does not count indirect blocks, but it does count blocks in
sparse files that are not actually allocated.
