$ dayslash -d --output yyyy/mm/dd 20120304

2012/03/04

$ echo 050607 | dayslash --output H:M:S 1

5:6:7

$ echo 20111201235958 | dayslash --output m/d 1

12/1

$ echo - | dayslash --through - --output yyyy/mm/dd 1

-

$ echo 20111201235958002 | dayslash --output yyyy/mm/dd_HH:MM:SS.sss 1

2011/12/01_23:59:58.002

$ echo 20111201235958002 | dayslash --output yyyy/mm/dd_HH:MM:SS.s 1

2011/12/01_23:59:58.2

Note

Data consistency of input is not checked.

"dayslash" command sees only number of digit of input data.

Description for --input

output to yyyymmddHHMMSSsss or yyyymmddHHMMSS or

yyyymmdd or HHMMSS in this order.

If you designate --output <format>, output format follows

the desinated format.

Example

$ echo 2012/03/04 | dayslash --input yyyy/mm/dd 1

20120304

$ echo 5:6:7 | dayslash --input H:M:S 1

050607

$ echo 2011/12/1_23:59:10 | dayslash --input yyyy/m/d_HH:MM:SS 1

20111201235910

$ echo 2011/12/1_23:59:10.0 | dayslash --input yyyy/m/d_HH:MM:SS.s 1

20111201235910000
