Ya itu benar-benar -14 di Edmonton dan terasa seperti -23. Waktu yang tepat untuk menghabiskan akhir pekan panjang di dalam bermain Tomb Raider 2013 yang baru tiba! Mungkin memoles Resume untuk pindah ke Vancouver atau Montreal ...

Simpan perubahan file `~ / .bashrc".

Untuk menampilkan informasi Ubuntu yang Anda butuhkan screenfetch:

sudo apt install screenfetch

Ada paket tampilan serupa untuk screenfetchjadi berbelanja!

Jika Anda ingin prompt perintah yang sama dengan "─────────" membagi garis antara perintah, ubah baris ini:

if [ "$color_prompt" = yes ]; then
    PS1='───────────────────────────────────────────────────────────────────────────────────────────
${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
else
    PS1='───────────────────────────────────────────────────────────────────────────────────────────
${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
fi
unset color_prompt force_color_prompt

Perhatikan panjang garis pemisah bertepatan dengan lebar screenfetchkeluaran. Dalam hal ini lebarnya 92 karakter dan gnome-terminalpreferensi diatur sesuai.

@ WinEunuuchs2Unix dapatkah Anda membuat bash scrip sebagai tempat penyimpanan github? saya punya beberapa saran untuk membuatnya lebih tangguh terhadap ukuran jendela terminal (pada hard endline wraping temins seperti wsl) dan beberapa saran bagaimana meningkatkan kalender untuk menyertakan suport untuk beberapa bahasa versi saya yang dimodifikasi sedikit berbeda tetapi dapat diukur: D
