Tidak peduli berapa banyak saya mengatur HISTSIZE
variabel lingkungan menjadi lebih besar dari 5000, ketika mencetak daftar sejarah dengan history
builtin, itu hanya mencetak 5.000 perintah terakhir. Saya memerlukan itu karena saya sering memiliki yang besar .bash_history
yang melebihi 5000 baris, dan kadang-kadang seseorang perlu mengatasi perintah awal dengan menekan Ctrl-R, tetapi jika perintah itu lebih dari 5000 perintah sebelumnya, saya tidak dapat mengaksesnya menggunakan mekanisme itu. Saya tahu saya bisa menggunakan grep
pada .bash_history
, tapi saya pikir Ctrl-Rmekanismenya akan jauh lebih cepat (dan nyaman). Saya menggunakan gnu bash versi 4.1.
Itu adalah konten lengkap file .bashrc saya:
