Let’s say that you work under your current home directory where you have created a file and you want to extract the full path in order to share it with someone else or to use it in another script. An easy way to do that is using the readlink or the realpath:
readlink
For example:
readlink -f myfile.csv
And we get the full path:
/home/gpipis/my_projects/2021/project_a/myfile.csv
realpath
Another option is to use the realpath.
realpath myfile.csv
And we get the full path:
/home/gpipis/my_projects/2021/project_a/myfile.csv
