If they are all in the same folder then what's wrong with

Code:

cp folder/*.txt folder/*.csv otherlocation/

As far as that hideous find command line is concerned, is it really not more elegant to say

Code:

find . \( -name "*.csv" -o -name "*.txt" \) ...

(You have to escape the parens from the shell, something the find manual page doesn't typically stress enough.)

Thanks all. I had one lat thing i need to schedule it through cron to run every first wednesday of the month.

I know crontab -e will take me to cron and editing it in Vi editor:

50 23 * * 0-5 /usr/sandeep/TestAutomate.sh


how can we get this thing run every first wednesday of the month?

Thanks,
Sandeep

Add the following lines at the beginning of your script:

eval "date '+MM=%m'"
[ -f $HOME/TestAutomate.M$MM ] && exit
rm -f $HOME/TestAutomate.M??; touch $HOME/TestAutomate.M$MM

and schedule it to run on Wednesdays ONLY!!

can you please explain this a bit? Will be helpfull

Thanks,
Sandeep

Tthe traditional solution would be a self-scheduling at job. Then you can use arbitrary commands to specify the scheduling.

Code:

#!/bin/sh
: ... commands
when=`date -d "4 weeks"`
# code to figure out when to wait 5 weeks left as an exercise
echo "$0" "$@" | at $when

Unilover's solution relies on finding a file with this month's month number, and not doing the copying if it already exists. An alternative would be to compare the day number to 7, and only run if it is less. (Not having any external state would seem to me like an advantage.)

The first line saves the two-digit Current-Month number in the MM variable (e.g. MM=03 for March).

The second line checks to see if there is a file named AutoTester.M$MM (e.g. AutoTester.M03) in the user's Home-Directory, exits the script. So, for all subsequent Wednezdays (i.e. the second, third, ... ) in the month, it would exit without doing anything.

The third line, which will only be reached and executed when there is NO AutoTester.M$MM file (i.e. THE FIRST WEDNEZDAY OF EACH MONTH), first removes all previous such files (for previous months) and then creates that file for the CURRENT MONTH (which will cause the second line to sense it and exit for all subsequent executions on other Wednezdays) and then continues to the rest of the script.
