Bash script variable substitution help

[eccapt]

Given the following code I am expecting the variable NewFile to be: myfile.txt.pdf
However my system is returning the following: ".pdfest.txt" without quotes.

                FileName=`head $f -n1 | awk -F/ '{print $NF}' | sed 's/\"//'`
                #this returns "myfile.txt" no quotes
                Ext="${FileName##*.}"
                xPdf=".pdf"
                fn="${FileName}"

                NewFile="${fn}${xPdf}"

Any help is appreciated, please note that I am newb and know little to nothing about linux.

that's strange...


i tried:

#!/bin/bash

# FileName=`head $f -n1 | awk -F/ '{print $NF}' | sed 's/\"//'`
#this returns "myfile.txt" no quotes
FileName=myfile.txt

Ext="${FileName##*.}" # no effect on outcome
xPdf=".pdf"
fn="${FileName}"
NewFile="${fn}${xPdf}"

echo $NewFile
# outputs: myfile.txt.pdf

it does what is expected.
are you sure you're using bash...?
