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.
