Question

Write a bash shell script that emulates the basic functionality of the ls command for the present working directory. Specifically for each object in the directory your script must:

determine & display whether it is a directory, file, or other

determine & display the file owner's permissions for directories and files

utilize one or more Linux functions to minimize redundancy.

add error handling for SIGINT

hint - Use test commands for testing files within the loop (man test)

Example of the script output:

[jalcorn@blanca]$ ./quiz1
/home/jalcorn/hwfile is a file with owner permissions: rw-
/home/jalcorn/hwscript is a file with owner permissions: rwx
/home/jalcorn/testdir is a directory with owner permissions: r—
