Artikel ini cukup ringkas dan padat, sangat berguna bagi kamu yang sedang membuat script custom dengan Bash. Silakan search pada web ini untuk tutorial khusus dengan Bash. Secara umum sintaks Date pada Shell Script adalah: [sourcecode]date +FORMAT[/sourcecode] atau [sourcecode]date +"%FORMAT"[/sourcecode] atau [sourcecode]date +"%FORMAT%FORMAT"[/sourcecode] dan, misalnya untuk menampilkan tanggal dengan output 02-27-16 sintaksnya: [sourcecode]date +"%m-%d-%y"[/sourcecode] untuk menampilkan waktu tambahkan sintaks %T, outputnya 19:56:23. Jika ingin tampil dalam format jam 12-an, silakan gunakan sintaks: %r. Tabel lengkap sintaks:
