This is a cheat sheet for how to perform various actions to ZSH, which can be tricky to find on the web as the syntax is not intuitive and it is generally not very well-documented.
| Description | Syntax |
|---|---|
| Get the length of a string | ${#VARNAME} |
| Get a single character | ${VARNAME[index]} |

| setopt auto_cd # if a command isn't valid, but is a directory, cd to that dir | |
| setopt auto_pushd # make cd push the old directory onto the directory stack | |
| setopt pushd_ignore_dups # don’t push multiple copies of the same directory onto the directory stack | |
| setopt pushd_minus # exchanges the meanings of ‘+’ and ‘-’ when specifying a directory in the stack |
