All paths to directories with Linux commands are stored within a variable called $PATH. Once a command is being called its path is stored additionally in a notebook called hash to speed up the look up next time.
The hash is a shell builtin command and
help hash gives a very short description. One option -t is described as printing all paths collected within the hash, and so I typed:
being sure I would get a listing of the hash's content.
However I got this:
bash: hash: -t: option requires an argument
What argument does it require?
What am I doing wrong?
How to show the content of the hash table?
