Alternatives to sig

Search streaming text interactively in your terminal. The listings below can replace it for an important use case. Each note says what changes if you switch.

Replacements

Listings that take over the same core job as sig.

  • fzf

    A fuzzy filter for any list: files, command history, processes, branches, anything you can pipe into it.

    FreeOpen sourceWindowsmacOSLinuxAndroidCommand line

    fzf filters any list piped on standard input and adds shell history integration, preview windows and Vim plugins, though it does not advertise rerunning a source command as sig does.

  • Television

    Search files and other data through a terminal fuzzy finder.

    FreeOpen sourceWindowsmacOSLinuxCommand line

    Television searches files and other data through configurable channels for each source, rather than matching live streaming text or rerunning a source command.

  • peco

    An interactive command-line filter that narrows piped input as you type and returns the selection.

    FreeOpen sourceCommand line

    peco narrows piped input interactively and returns the selection, with fewer integrations and no stated support for rerunning a source command.

Also worth comparing

These listings name sig as their own alternative, so the relationship runs both ways.

  • fzy

    A fast, simple fuzzy text selector for the terminal with an advanced scoring algorithm.

    FreeOpen sourcemacOSLinuxCommand line

    sig searches streaming text interactively as data arrives and can rerun a source command, a narrower focus than fzy's general list selection.
