Looking on how to write Unix shell script for filename pattern matching? There’s several way you can write it using regular expression technique in scripting.

Let’s say you have a scenario where you want to perform certain command execution e.g file processing if certain filename exist in certain folder.

Here’s the example of a simple Unix shell script you can use to accommodate your file processing scenario.

#!/bin/bash
 
V_SOURCE_PATH=/export/home/oracle
 
cd $V_SOURCE_PATH
 
for file in ./*_new.txt ; do
 
        if [ -e "$file" ] # Make sure file exists and isn't an empty match
        then
        echo "Filename with pattern _new.txt exist"
        else
        echo "Filename with pattern _new.txt not exist"
        fi
 
done
