Patterns

[ryedunn]

I stumbled upon this from a post on SO and this is exactly what I was looking for. Unfortunately, Im a bit confused with some of the functionality.
Patterns for example, if I wanted to remove all 'ls' commands... I thought I could use something like hist d ^ls\s, but this doesnt seem to work as I would have hoped. Although I can confirm your example in the documentation hist d $'*(\n|;)' works just fine.
Any suggestions on what Im doing wrong here?

• The pattern syntax is not regex, but glob expressions. This is the same syntax that's used for the $HISTORY_IGNORE parameter.
• You need to quote the pattern or else zsh will perform filename generation on your argument before passing it to hist.

So, for your case, to remove all lines starting with the word ls, you should use hist d 'ls *'.
