Iterate over files and search for a pattern

This script iterates over all XML files in the current directory, searches for the pattern "Name=" and extracts the XML value. Fnally renames the original XML file with the recovered value.

Script

#!/bin/bash

for filename in ./*.xml; do
    echo Checking $filename
    aux1=`grep -oE ' Name=\"(.*)\"' < $filename | cut -f 2 -d '"'`
    cp $filename $aux1.xml
done

echo Done!

Remarks

• grep -oE searches ONLY for a pattern
• grep -oE < $fileName is more efficient than cat $filename | grep -oE
