appending files
hi i have this very interesting task, and i need some inspiration. i have a directory with say 10 fcgi files (text files): now i would like to have a temp.fcgi file which contains all of the date from the .fcgi files (appended). however, i want my program to update the temp.fcgi file if new .fcgi files are added the directory. i was thinking something like testing the combined size of the .fcgi files compared to temp.fcgi and if it differs then wipe temp.fcgi and generate a new one? how can that be done? -martin -- -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: appending files
Might be better off using a hash with the filename and say last mod time. Then if a new file or the last mod time is different, then rebuild your data.

Re: appending files
interesting, but no. i can download these .fcgi files from a database and they are quite generic (they contains loads of records). all i wanted is to collect all therecords in one big fcgi file for outputting and sorting. but i may download new .fcgi files regularly and i want them included in the big fcgi file as well. however, i dont want to do the include process with each run of the program! :) martin On Mon, Feb 25, 2002 at 07:48:07AM -0800, Wagner-David wrote: Might be better off using a hash with the filename and say last mod time.

RE: appending files
Unless you do some type of check, then on the data, you will not know if you have updated data or not. I can change a H to J in the file and the size of the file has not changed, but it is not the same file. You will have to come up with some way either within your database or on the Perl side to check. Size alone will not guarantee you anything as to what is in the file.

Re: appending files
I would write out a file that gives the files included in the big .fcgi file as well as their checksums. Then you could check against the database to see if it needs to be updated ( if you will never change an old file, then the checksum is not needed, but be sure to plan ahead!)
