count item seq [option]…

A wrapper around the function cl-count (see Searching Sequences in GNU Emacs Common Lisp Emulation). This command can be used for comparing lists of strings.

expr str [separator] [arg]…

An implementation of expr using the Calc package. See The GNU Emacs Calculator.

ff directory pattern

Shorthand for the function find-name-dired (see Dired and Find in The Emacs Editor).

gf directory regexp

Shorthand for the function find-grep-dired (see Dired and Find in The Emacs Editor).

intersection list1 list2 [option]…

A wrapper around the function cl-intersection (see Lists as Sets in GNU Emacs Common Lisp Emulation). This command can be used for comparing lists of strings.

mismatch seq1 seq2 [option]…

A wrapper around the function cl-mismatch (see Searching Sequences in GNU Emacs Common Lisp Emulation). This command can be used for comparing lists of strings.

set-difference list1 list2 [option]…

A wrapper around the function cl-set-difference (see Lists as Sets in GNU Emacs Common Lisp Emulation). This command can be used for comparing lists of strings.

set-exclusive-or list1 list2 [option]…

A wrapper around the function cl-set-exclusive-or (see Lists as Sets in GNU Emacs Common Lisp Emulation). This command can be used for comparing lists of strings.

substitute new old seq [option]…

A wrapper around the function cl-substitute (see Sequence Functions in GNU Emacs Common Lisp Emulation). This command can be used for comparing lists of strings.

union list1 list2 [option]…

A wrapper around the function cl-union (see Lists as Sets in GNU Emacs Common Lisp Emulation). This command can be used for comparing lists of strings.
