Top Forums Shell Programming and Scripting Extract date from filename and create a new file Post 302501503 by Chubler_XL on Thursday 3rd of March 2011 06:31:13 PM
Old 03-03-2011
Code:
FILENAME="/dprod/informatica/Fuentes/CRED20102009.csv"
DIRNAME=$(dirname $FILENAME)
echo $FILENAME | sed 's/^.*\(..\)\(..\)\(....\)\....$/[Comercial.AACPWM001]\n$$Date = \3\2\1 aaammdd format/' > $DIR/Parameters.txt

The string in your parameters.txt file is just about long enough to fetch the date into another shell var and then cat it out (this also makes it easier to update the parameters format at a later date):

Code:
FILENAME="/dprod/informatica/Fuentes/CRED20102009.csv"
DIRNAME=$(dirname $FILENAME)
DATESTR=$(echo $FILENAME | sed 's/^.*\(..\)\(..\)\(....\)\....$/\3\2\1/')
 
cat <<EOF > $DIR/Parameters.txt
[Comercial.AACPWM001]
\$\$Date = $DATESTR aaammdd format
EOF
