Calculate number of days between two days on sun solaris only

[jmarioscs]

Hello!

Must list "n" files from a given directory (exe: / export / home / test /), to recover part of the file names in a variable and then compare the variable with a specific date.

Eg

I have the file TEST-2012-09-18.LOG, just need to assign the value to a particular variable 09.18.2012 and subsequently compare this variable (date) with the current date, if the difference is more than 30 days, I delete the file.

I await return of you!!

The find command I believe will do what you want. below is the command that I use to search for specific files that are older than 30 days and delete them. In my case I am only looking at files in the directory named backup and sub directories for files that start with the letters xln.

find /backup/* -name xln* -mtime +30 -exec rm -f {} \; >/dev/null 2>&1

Tolson's solution assumes the last modification times of the files matches the dates in the filenames; if that is the case then it is the best way to go about it.

Otherwise you may find this ksh function useful for your date calculations.

Personally I usually use perl to do date calculations with the C-like POSIX functions, for example this will return the date 30 days ago:

perl -e 'use POSIX;($d,$m,$y)=(localtime time)[3..5];print strftime "%Y-%m-%d\n",localtime(mktime(0,0,0,$d-30,$m,$y));'

If you choose to use that, I would extract the date from the filename without dashes and just do a numerical comparison, e.g. if (20120913 < 20120917) then delete it.
