====== Archive and remove files older than a specified date ======

This small script realizes the routine task of finding and archiving files older than a given date from a directory structure.

<code bash>
#!/bin/bash

if [ ! -d "$2" ]; then
    echo "usage: $0 <timestamp> <directory>"
    exit 0
fi

ts="$1"
dir="$2"

tmpdir=`mktemp -d`
trap "rm -rf '$tmpdir'" exit

touch -d "$ts" "$tmpdir/tsfile" || exit

echo "+ finding files older than $ts in $dir"
find "$dir" -type f -not -cnewer "$tmpdir/tsfile" > "$tmpdir/filelist"

archive="archive-$ts-"`date +%s`".tgz"

echo "+ packing contents to $archive"
tar -czf "$archive" --files-from "$tmpdir/filelist" && { echo "+ removing files" ; cat "$tmpdir/filelist" | xargs -n1 rm -f ;}

echo "+ done"
