I have this shell file which is supposed to extract data from a different directory, but it tries to extract files from current directory with "$pwd". How can I specify a folder to extract these files from, such that it comes from /home/gnssb/Desktop/Data instead of /home/gnssb/Desktop/Data/shell_scripts
#!/bin/sh
ORIG_DIR=$(pwd)
basedir="../"
year=2016;
init_month=01;
end_month=01;
init_date=01;
end_date=26;
casesinp="${ORIG_DIR}/./cases-inp"
