UNIX for Dummies Questions & Answers

i had this scenario where i need to delete a file that is 6 months old which is no longer needed. basically the filename is in the format of PCARDDAILYmmddyyyy.txt where the mm is the month, dd is the day, and yyyy is the year.

Code:

e.g.
  PCARDDAILY05262009.txt 
  PCARDDAILY05252009.txt

assuming that there is PCARDDAILY05262009.txt and PCARDDAILY07252009.txt files. these files are more than 6 months and needs to be deleted. is there a single command that will delete these files? the reason why i need a single line of command is that i will put this command on a scheduler tool called TIDAL Enterprise Scheduler.

thanks,

you can make use of find command if you wanna delete them on the basis of creation date rather than filename basis..

please provide an example. thanks.

I mean if you file PCARDDAILY05262009.txt PCARDDAILY05252009.txt
created 6 months back then you can delete them, using find command..

Code:

find . -mtime +180 -exec rm -rf {} \;

great thanks. assuming that i have other files that are not in PCARDDAILYmmddyyyy.txt such as EATVDAILmmddyyyy.txt and i am only restricted to delete files that starts with PCARDDAILY*.txt. are other files that resides on the same directory will be deleted with this command:

Code:

find . -mtime +180 -exec rm -rf {} \;

i guess that will delete other files other than PCARDDAILYmmddyyyy.txt ...
so try this...

Code:

find . -type f -name "PCARDDAILY*.txt" -mtime +180 -exec rm -rf {} \;

that works thanks so much.
