unexpected EOF

edit

when i run cmd "source ~/.bashrc" i'm getting below error:

bash: /tmp/setup.sh.FUf31G670r: line 38: unexpected EOF while looking for matching `"' bash: /tmp/setup.sh.FUf31G670r: line 39: syntax error: unexpected end of file bash: [: 0: unary operator expected

my /opt/ros/melodic/setup.sh file is:

#!/usr/bin/env sh
# generated from catkin/cmake/template/setup.sh.in

# Sets various environment variables and sources additional environment hooks.
# It tries it's best to undo changes from a previously sourced setup file before.
# Supported command line options:
# --extend: skips the undoing of changes from a previously sourced setup file
# --local: only considers this workspace but not the chained ones
# In plain sh shell which doesn't support arguments for sourced scripts you can
# set the environment variable `CATKIN_SETUP_UTIL_ARGS=--extend/--local` instead.

# since this file is sourced either use the provided _CATKIN_SETUP_DIR
