Linux Shell Scripting Cookbook - Third Edition

How it works...

When the -F parameter is used with ls, all entries are appended with some type of file character such as @, *, |, and so on. For directories, entries are appended with the / character. We use grep to filter only entries ending with the /$ end-of-line indicator.

The first character of any line in the ls -l output is the type of file character. For a directory, the type of file character is d. Hence, we use grep to filter lines starting with "d."^ is a start-of-line indicator.

The find command can take the parameter type as directory and maxdepth is set to 1 since we don't want it to search inside the subdirectories.
