#!/bin/bash
# Move files older than 6 months to another directory

## Cronjob for this command:
##Move old irclogs at first day of the month.
#0 0 1 * * /path/to/move-old-irclogs.sh > /dev/null 2>&1
# Moveold function parameters:
# $1 = since date that is in filename
# $2 = original path
# $3 = destination path
# $4 = log of successfully moved files
# $5 = log or files that did not copy successfully, so original file not removed
function moveold {
# Create destination directory if it does not exist yet
mkdir -p "$3"
# List original files
for file in `ls -1 --color=none $2`
do
# If filename string value is smaller than 6 months ago
if [[ "$file" < "$1" ]]
then
# Preserve file date when copying
cp -p "$2$file" "$3$file"
# Check if files are the same.
# In awk part, $1 means result hash of sha256sum command.

else
