UNIX for Dummies Questions & Answers

Hi,

I'm a complete noobie at UNIX and have hit a problem.
I'm using the 'Talend' ETL tool to try and extract flat files from UNIX on a weekly basis.
The dates are maintained in a control table and the appropriate folder has been mounted.

I am using a component in 'Talend' which enable you to write a UNIX script to do this (I've been told this is the best approach!?).
So far I'm trying to use 'find' and access a folder which is held in context to get the files which are between EXTRACT_START_DATE and EXTRACT_END_DATE like this -

Code:

"find ./" + context.Dir_Data_Load_Files + "/  \
-mtime -" + String.valueOf((((new Date()).getTime()+(1000 * 60 * 60 * 24)-TalendDate.parseDate("yyyy-MM-dd", System.getProperty(jobName+"_EXTRACT_START_DATE")).getTime())/(1000 * 60 * 60 * 24))) + "\
-mtime +" + String.valueOf((((new Date()).getTime()-(1000 * 60 * 60 * 24)-TalendDate.parseDate("yyyy-MM-dd", System.getProperty(jobName+"_EXTRACT_END_DATE")).getTime())
/(1000 * 60 * 60 * 24))) + " -print"

The tool tells me that the find command is in an incorrect format.

Can anyone shed any light on this for me please?

Thanks

Say you want a start of 15 Apr 2010 and an end of 20 Apr 2010

Code:

touch -t 201004150000 dummy1
touch -t 201004202359 dummy2
find /path -type f  \( -newer dummy1  -a ! -newer dummy2 \)
