how to reduce one day from this
Jan013.gz ---> it should be Jan012.gz

thanks

 

[CALYAN]

I used this to extract somepart of the date
FILENAME=$(date +%b%d)
printf $FILENAME

It generates output like this.?
Jan13(example)

But I need Jan13.gz

how to add this?

print $FILENAME

The ';' can be omited :

FILENAME=$(TZ=TZ+23 date +%b%d).gr
print $FILENAME

The command works fine on my aix box (with ksh):

set -vx
FILENAME=$(TZ=TZ+23 date +%b%d).gr
print $FILENAME


FILENAME=$(TZ=TZ+23 date +%b%d).gr
+ + date +%b%d
+ TZ=TZ+23
FILENAME=jan13.gr
print $FILENAME
+ print jan13.gr
jan13.gr
