Create an index log that lists the names of desired directories and ID values pulled from .csv file within each directory. This version of the script is depricated and has been replaced by dir_name_indexLogger2.sh, but I still like some of the code from this so I wll keep it around

concatenated_index_log.sh

#!/bin/bash
# save directory names and their associated ID's into an index log

# set the proper permissions for all files created by this script
umask 007 

# make sure that the log file exists
LOG=/filepath/PARENT_DIR/logs/index_log.tsv
touch $LOG

# find the desired directories, they always have  ~PATTERN~ in name
FILES=$(find /filepath/PARENT_DIR/ -maxdepth 1 -type d -name PATTERN)

# append the list of all desired directory names into the log
# also add the ID value, found in the directory's Information_sheet.csv
for i in $FILES; do
echo -e "$(basename $i)\t$(grep "ID" $i/Information_sheet.csv | cut -f 2 -d ,)">> $LOG;
done

# remove the duplicate entries
sort -u $LOG -o $LOG
