bash script to find old files based off date in file name

Question

I\'m developing a bash script that needs to search out files within a single directory that are \"old\" based off a variable that specifies how many days need to pass before the

Answer 1

Create a bash script isOld.sh like this:

#!/bin/bash

fileName=$1
numDays=$2

fileDt=$(echo $fileName | sed 's/^[^-]*-\([^.]*\)\..*$/\1/')
d1=$(date '+%s')
d2=$(date -d $fileDt '+%s')
diff=$((d1-d2))
seconds=$((numDays * 24 * 60 * 60))
[[ diff -ge seconds ]] && echo $fileName

Then give execute permission to above file by running:

chmod +x ./isOld.sh

And finally run this find command from top of your directory to print files older than 7 days as:

find . -name "contents-*" -exec ./isOld.sh {} 7 \;
