zmv manual is in the
zshcontrib man page.
You can reach it directly with
LESS="$LESS +/^ *zmv *\\[" man zshcontrib
LESS="$LESS +/zmv" man zshcontrib which takes you a few lines further up because
zmv is mentioned in the description of
zcp). You can use
man zshall instead of
man zshcontrib if the
zshall man page is available on your system.
If you use Info, you can reach it by running
info zsh and typing
i then entering
info --index-search=zmv zsh
The zsh guide has a fairly detailed section on
zmv on this stackexchange will turn up several usage examples of varying complexity.
You can perform a dry run with
zmv -n (
-n is a common way of requesting a dry run).
To benefit from
zmv and friends, it helps to have code like the following in your
alias zmv='noglob zmv'
alias zcp='noglob zmv -C'
alias zln='noglob zmv -L'
alias zsy='noglob zmv -Ls'
