Conditional File Movement script scheduled using CRON job
Hi All,
i am trying to automate a process and have to create a unix script like wise. I have a scenario in which i need to automate a file movement. Below are the steps i need to automate.
1. Check whether a file (Not Fixed name-Pattern search of file say 'E*.dat') is present in a directory /hm/srcfiles. In this directory, there will be files placed by a JSP on adhoc basis like E1.dat,E2.dat,E3.dat ......
2. A script/Job keeps sniffing this directory for files of this kind.... the moment it finds one, it should transfer the file to other directory say /hm/tgt but with renaming it to 'FILE.dat'. This transfer is conditional, the file movement should happen only if the /hm/tgt directory does not contain 'FILE.dat', and if 'FILE.dat' is present, it should wait and try to move the file again untill succeded.
3.The cleanup of file 'FILE.dat' from /hm/tgt/FILE.dat happens by another shell script called by a different application. I am kind of able to write that (I have not worked with unix scripting much
)
4.I guess CRON job scheduling should be used for triggering the file movement script, correct me if i am wrong.
5.This CRON job should run contineously and trigger the script when ever the
file named like 'E*.dat' arrives. Also if many files are present in /hm/src directory, all the files should be processed sequentially
Thanks for the patience to read the explaination. I do not know scripting much OR have used CRON job scheduling before. Can someone help me in this regard. I a sound too naive with UNIX, it is because i am

load_datafile
load_datafile(3alleg4) Allegro manual load_datafile(3alleg4) NAME
load_datafile - Loads a datafile into memory. Allegro game programming library. SYNOPSIS
#include <allegro.h> DATAFILE *load_datafile(const char *filename); DESCRIPTION
Loads a datafile into memory in one go. If the datafile has been encrypted, you must first call packfile_password() to set the appropriate key. If the datafile contains truecolor graphics, you must set the video mode or call set_color_conversion() before loading it. Example: /* Load the resources for our game. */ DATAFILE *dat = load_datafile("game.dat"); if (!dat) abort_on_error("Couldn't load sound resources!"); /* Use resources. */ ... /* Destroy them when we don't need them any more. */ unload_datafile(dat); RETURN VALUE
Returns a pointer to the DATAFILE, or NULL on error. Remember to free this DATAFILE later to avoid memory leaks. SEE ALSO
