# Since bash works in the context of a current directory, you might want to
# run your command in some other directory. We have cd for changing location:
cd ~ # change to home directory
cd # also goes to home directory
cd .. # go up one directory
# (^^say, from /home/username/Downloads to /home/username)
cd /home/username/Documents # change to specified directory
cd ~/Documents/.. # still in home directory..isn't it??
cd - # change to last directory
# => /home/username/Documents
# Use subshells to work across directories
(echo "First, I'm here: $PWD") && (cd someDir; echo "Then, I'm here: $PWD")
