Last touched file by a specific program ?
i have a directory where all .csv files are available. i have 3 perl programs(ex: a.pl,b.pl,c.pl) which continuously runs every 1 minute to scan all files in that directory. now i have 2 questions
1) how can i write an app lock on that particular folder to make sure only one program will scan that folder to get files so that other program will not catch same files ?
2) how to know if one perl program already touched a particular file ?
ex:
a.pl program scanned a folder and accessing 1.csv, 2.csv and 3.csv 3 files. Now it released app lock, now b.pl program accessing same folder but it should not read 1.csv, 2.csv and 3.csv files since a.pl already reading or accessed those folders.
Note: i don't want to rename any files in this process. How to do this ?
any help would be appreciated

bb-csvinfo.cgi
BB-CSVINFO.CGI(1) General Commands Manual BB-CSVINFO.CGI(1)
NAME
bb-csvinfo.cgi - CGI program to show host information from a CSV file
SYNOPSIS
bb-csvinfo.cgi
DESCRIPTION
bb-csvinfo.cgi is invoked as a CGI script via the bb-csvinfo.sh CGI wrapper. Based on the parameters it receives, it searches a comma-
separated file for the matching host, and presents the information found as a table.
bb-csvinfo.cgi is passed a QUERY_STRING environment variable with the following parameters:
key (string to search for, typically hostname)
column (columnnumber to search - default 0)
db (name of the CSV database file in $BBHOME/etc/, default hostinfo.csv)
delimiter (delimiter character for columns, default semi-colon)
CSV files are easily created from e.g. spreadsheets, by exporting them in CSV format. You should have one host per line, with the first
line containing the column headings. Despite their name, the default delimiter for CSV files is the semi-colon - if you need a different
delimiter, invoke bb-csvinfo.cgi with the "delimiter=<character>" in the query string.
Example usage
This example shows how you can use the bb-csvinfo CGI. It assumes you have a CSV-formatted file with information about the hosts stored as
$BBHOME/etc/hostinfo.csv, and the hostname is in the first column of the file.
Use with the bbgen --docurl
The --docurl option to bbgen(1) sets up all of the hostnames on your Xymon webpages to act as links to a CGI script. To invoke the
bb-csvinfo CGI script, run bbgen with the option
--docurl=/cgi-bin/bb-csvinfo.sh?db=hostinfo.csv&key=%s
