Re: how to search for commands

Re: how to search for commands
hmm. but can I use a wildcard with any of them. For example search for all commands which contain the word nice. Which would bring up ionice.

How do you search for commands? In powershell you have the get-command cmdlet. Is there anything equivalent in unix?
