Top Forums Shell Programming and Scripting How to make a script to run everytime a new file is copied into a directory?? Post 302307439 by pludi on Wednesday 15th of April 2009 10:58:31 AM

GNU find supports the -newer option, so you could do this (pseudo code)
Code:
find files with modification time later than reference file
loop over the list
    do whatever you have to do
update reference file

Using this via cron would waste minimal resources if nothing changes.

NAME
find - find files meeting a given condition SYNOPSIS
find directory expression EXAMPLES
find / -name a.out -print # Print all a.out paths find /usr/ast ! -newer f -ok rm {} ; # Ask before removing find /usr -size +20 -exec mv {} /big ; # move files > 20 blks find / -name a.out -o -name '*.o' -exec rm {}; # 2 conds DESCRIPTION
Find descends the file tree starting at the given directory checking each file in that directory and its subdirectories against a predi- cate. If the predicate is true, an action is taken. The predicates may be connected by -a (Boolean and), -o (Boolean or) and ! (Boolean negation). Each predicate is true under the conditions specified below. The integer n may also be +n to mean any value greater than n, -n to mean any value less than n, or just n for exactly n. -name s true if current filename is s (include shell wild cards) -size n true if file size is n blocks -inum n true if the current file's i-node number is n -mtime ntrue if modification time relative to today (in days) is n -links ntrue if the number of links to the file is n -newer ftrue if the file is newer than f -perm n true if the file's permission bits = n (n is in octal) -user u true if the uid = u (a numerical value, not a login name) -group gtrue if the gid = g (a numerical value, not a group name) -type x where x is bcdfug (block, char, dir, regular file, setuid, setgid) -xdev do not cross devices to search mounted file systems Following the expression can be one of the following, telling what to do when a file is found: -print print the file name on standard output -exec execute a MINIX command, {} stands for the file name -ok prompts before executing the command SEE ALSO
