Merge script

I needed to combine all the files in two different directories. The challenge was that in two different directories, two different files had the same name. So I wrote a merge script to rename the file from the source directory if the name already existed in the target directory. It appears below:

#!/bin/bash

# Merge the contents of two directories, renaming duplicate files so that no files are overwritten

# usage merge.sh destdir

SRC1="$1"

DEST="$2"

for FILE in $( ls "$SRC1" ); do

let "i = 0"

FN="$DEST/${FILE/%.jpg/-$i.jpg}"

while [[ -e "$FN" ]]; do

let "i += 1"

FN="$DEST/${FILE/%.jpg/-$i.jpg}"

done

ln -v "$SRC1/$FILE" "$FN"

done

It worked for my purposes.
