# Backup Regular files to archive/timestamp
#
NOW=$(date +"%Y-%m-%d-%H-%M-%S")
#
#
if [[ -z $1 ]]
  then
  BACKUPDIR=archive/$NOW
else
  BACKUPDIR=$1/$NOW
fi
mkdir -p $BACKUPDIR
#
for file in $(ls -p | grep -v /$)
do
  cp -p $file $BACKUPDIR/
done
#
exit 0
</code>


===== File =====
<code bash>
#!/bin/bash
#
if [[ ! ("$#" == 1) ]]; then
  echo "File name required!"
  exit 1
fi
filename=$1
#
NOW=$(date +"%Y-%m-%d-%H-%M-%S")
mkdir -p archive
cp -p $filename archive/$filename.${NOW}
</code>
