What is the difference between the commands test -e path and test -f path?
The test command is used to perform checks and comparisons on files and values. The -e option tests if a given path exists, regardless of its type (file, directory, link, etc.). The -f option tests if a given path exists and is a regular file, not a directory or a special file. For example, if we have a directory named dir and a file named file, we can use the test command as follows:
test -e dir && echo ''dir exists'' dir exists test -f dir && echo ''dir is a regular file'' (no output) test -e file && echo ''file exists'' file exists test -f file && echo ''file is a regular file'' file is a regular file
