Data Script That Appends
I am trying to write a bash script that takes a file as an argument and appends my name if this file ends in .txt... I am not sure how to do this though. Any help is greatly appreciated!

Check this
Proabably lengthy and complicated but works

Run this Script

filename=$@
length=`echo $filename | wc -c`
length=`expr $length - 1`
length1=`expr $length - 3`
verify=`echo $filename | cut -b$length1-$length`

if [ "$verify" = ".txt" ]
then
echo "My name" >> $filename
else
echo "Cannot append My name"
fi

Check for file extension of ".txt" Using expr regular expression

Code:
if expr $filename : '^.*\.txt$'
then
   echo "my name" >> $filename
fi

Okay, I actually have figure out how to get this script to append my name to the file. Now I want to figure out how to prepend if the user inputs a "-p" flag and print files that I am appending if the user inputs a "-v" flag. This is my code thus far... The flags do not work.

Code:
if [ $@ = *.txt ] ; then

        mv $@ $@.Name

elif [ $1 = -p ] ; then

        mv $@ Name.$@

elif [ $1 = -v ] ; then

        echo $@

else

        echo "Error - Can Not Append"

fi

Code:
#!/bin/bash
file=$1
case $file in 
 *.txt) newfile=${file%*.txt}"-myname.txt"
esac
mv $file $newfile
