I've given you all the pieces. Have you tried anything with them?

You need a [[CC]YY]MMDDhhmm[.ss] date. How do you make a [[CC]YY]MMDDhhmm[.ss] date?

man date would be a good start. What do those % things you're putting into date mean?

Code:
...
       %d     day of month (e.g., 01)
       %H     hour (00..23)
       %m     month (01..12)
       %M     minute (00..59)
       %S     second (00..60)
       %Y     year
...

So you can make a date of the form required by giving it the right format string.

So that'd be touch -t $(date -d "2012-07-24 + $i day" "+%Y%m%d%H%M%S") filename

TZ Specifies the timezone, unless overridden by command line parameters. If neither is specified, the setting from /etc/localtime is used. AUTHOR
