About

This project creates symbolic links with the same base filename if the file extension is *.s within the directory that is provided as an argument, and skips the rest of the files. Also, one should know that the symbolic link always ends in *.t extension.

These symbolic links can be tested using a separate script included in this repository.

How it works

start.sh

1. It will check if the directory argument is empty. If yes, it will display the usage and exit (exit 1).
2. If the argument is not empty, the script will start checking if there are files that end in *.s extension inside the provided path, and it will exit if such files do not exist (exit 2).
3. If the files are present, the script will start creating symbolic links and it will write the paths to results.txt.

test.sh

1. It will check if the results.txt exists. If not, it will return Nothing to test here. and exit (exit 1).
2. If the results.txt does exist, the script will parse path by getting the first field using awk and by removing the single quotes globally (') using sed. After parsing, the values will be assigned to FILES variable.
3. Using the FILES variable, the script will check if each file exists and if it is a symbolic link.
4. If it is not a symbolic link, it will display an error that it does not exist.
5. Successful test results will display something like this: /path/to/file is a symlink.
