Syntax standard dari penanggalan adalah :
date +"%d-%m-%y"Output :
14-07-13Untuk membuat tahun menjadi 4 digit :
date +"%d-%m-%Y"Output :
14-07-2013Untuk menampilkan jam saja :
date +"%T"Output :
04:42:42Untuk menampilkan format waktu 12 jam :
date +"%r"Output :
04:44:21 AMUntuk menampilkan waktu dalam format HH:MM :
date +"%H:%M"Output :
04:47Sekarang bagaimana caranya menampilkan tanggal/waktu didalam variabel shell script?
Cukup tambahkan baris dibawah ini kedalam shell script anda
NOW=$(date +"%m-%d-%Y")
Contoh shell script backup dengan penanggalan
#!/bin/shContoh shell script diatas akan menghasilkan file backup dengan format seperti ini :
NOW=`date "+%d.%m.%Y.%H"`
tar -cf /path/storage/backup/anda/fileanda.${NOW}.tar /path/file/yang/akan/anda/backup
gzip /pat/storage/backup/anda/fileanda.${NOW}.tar
