UNIX for Dummies Questions & Answers

Hi Vino,

Thank you so much.... Its working.
But we need to change the month as

month="jan feb mar apr may jun jul aug sep oct nov dec"

One more thing, I get the following message for the month when it cannot find the file.

cp: Insufficient arguments (0)
Usage: cp [-f] [-i] [-p] f1 f2
cp [-f] [-i] [-p] f1 ... fn d1
cp -r|R [-f] [-i] [-p] d1 ... dn-1 dn

Thanks

Why do you need to change the month ?

You wanted the latest files if available. So you start from back. If there ever is a dec file, use that, else keep going backwards. In your case, if jan is there copy that as well and then do the same with feb etc. and keep going on.

For your second part, there should be a break statement. I forgot to add that

Code:

#! /usr/bin/ksh

YEAR=`date +%y`
month="dec nov oct sep aug jul jun may apr mar feb jan"
for mon in $month
do
file=`ls *"$mon"* 2>/dev/null`
FILE=${file%%_$mon$YEAR}
[[ -f "$file" ]] && cp $file $FILE && break;
done

Let me know if break works. Else try an exit in it place.

Hi Vino,

Thank you so much. The break worked.

If there are many files of different months. The file would not copy the latest but infact it does the opposite.

After changing the month to start from Jan. It will check jan first, next feb & so on...& it will copy the latest file which is present.

You can save the unnecessary calls to the cp command.

Keeping
month="dec nov oct sep aug jul jun may apr mar feb jan",

and changing this line

[[ -f "$file" ]] && cp $file $FILE && break;

to

[[ -f "$file" ]] && cp $file $FILE && exit 0;

Vino

I modified the following lines :-

MONTH=`date +%b`
YEAR=`date +%y`
month=`echo $MONTH | tr '[A-Z]' '[a-z]'`

Hope this works....

Hi Vino,

I changed as mentioned but its not working properly..

I had three months file i.e. sep, jun & may of 2005.

But it came out after copying jun's file instead of sep file.

Thanks

Try changing initial lines to ...

MONTH=`date +%b`
YEAR=`date +%y`
month=`echo $MONTH | tr '[A-Z]' '[a-z]'`

Hope this works...
